Many idiomatic expressions tested on the exam involve prepositions. There's no overarching grammatical rule that tells you which prepositions go with which verbs. Again, the rules are determined by usage, so you'll have to "listen" to the expression and determine if the verb is followed by the correct preposition.
Be on the lookout for commonly tested prepositions like "of," "at," "by," "in," "from," "to," and "for". If you have difficulty determining whether a usage is correct, try testing out the idiom in a simpler version of the sentence.
Example:
Although he was considered as a leading proponent for the controversial new initiative, the professor nevertheless sought refuge from the media uproar.
The sentence above becomes:
The professor was considered as a proponent.
Does anything sound unusual? Could this sentence be worded differently? In fact, to be, not as, is the correct idiom:
The professor was considered to be a proponent.
Would rather ß present tense if referring to myself and past tense if someone other than the subject is doing the action
Example: Would rather I speak ß present tense
Example: Would rather you spoke ß past tense
General Grammar definitions
So = therefore
So that = in order to/in order that
That = the fact that
Conjunctions that can join two independent clauses are: and, but, yet, for, or, nor
Don't start sentences with "Because"
Words requiring "how" (example: know how)
Know
Teach
Learn
Show
Always choose active over passive voice
Active example: Elaine purchased new software for the company
Passive example: New software was purchased for the company by Elaine
Another frequently tested grammatical error is unnecessary use of the passive voice. It's a good idea to become familiar with this type of error; it appears quite often in the answer choices of sentence correction questions.
As a reminder, the passive voice is in use when the action of the sentence is performed on the subject. The active voice is in use when the subject itself performs the action.
Example:
Active: Allison (subject) went (action) to the store to buy a cake (object).
Passive: The cake (subject) was bought (action) by Allison (object).
Preposition use
"To" or "Of" needs subject + verb NOT object + verb
Examples of subject: she, he, whoever, who, I
Examples of object: her, him, whomever, its, it
Either side of a form "to be" (were, was) must have subjects not objects on either side to agree.
A verb that ends in –ing is a gerund which is a verb acting like a noun. Try not to use gerunds if you can help it.
Adverbs, not adjectives modify verbs
Key identifier: Adverbs end in –ly
Correct example: I sure wish I were rich
Incorrect example: I surely wish I were rich
Word Usage
Some pairs of words, like fewer and less, are often used incorrectly because they're treated as synonyms. In fact, there is a solid rule that determines which one you should use, and the exam will test your ability to decide which is the correct option. The exam tests four such word pairs with particular frequency, so memorize the rules pertaining to them if you don't know them already.
Fewer/Less
Which of the two following sentences is correct?
-
The company fired no less than fifty employees.
-
The company fired no fewer than fifty employees.
The second sentence is correct. Why? Because you use less when you're talking about things you can't count (less pollution, less violence) but fewer when you're talking about things you can count (fewer pollutants, fewer violent acts).
Number/Amount
These words follow the same rule as less and fewer. Number is correct when you can count the thing being described (a number of cars, a number of people) and amount is correct when you cannot (amount of love, amount of pain).
Among/Between
Use between when only two options are available (between the red car and the blue car) and among when more than two options are available (among the five answer choices, among the many books).
If/Whether
Whether is correct when you're discussing two options (whether to get chocolate or strawberry ice cream) and if is correct for more than two options (if she should get ice cream, frozen yogurt, or a cookie).
On the GMAT, whether will (almost) always beat if
Incorrect: Her client didn't tell her if he had sent his payment yet.
Correct: Her client didn't tell her whether he had sent his payment yet.
Compared to v/s. Compared with: To show comparison between unlike things, 'compare to' is used. To show comparison between like things, 'compare with' is used.
e.g.
- He compared her to a summer day.
-
Scientists compare the human brain to a computer. (Unlike thing)
-
The police compared the forged signature with the original. (Like things)
There are two rules which you should consider. First read the usage notes from dictionary.com:
Compare usually takes the preposition to when it refers to the activity of describing the resemblances between unlike things:
He compared her to a summer day.
• Scientists sometimes compare the human brain to a computer.
Compare takes with when it refers to the act of examining two like things in order to discern their similarities or differences:
• The police compared the forged signature with the original.
• The committee will have to compare the Senate's version of the bill with the version that was passed by the House.
When compare is used to mean "to liken" (one) with another, with is traditionally held to be the correct preposition:
That little bauble is not to be compared with (not to) this enormous jewel. But "to" is frequently used in this context and is not incorrect.
Rule 1: Compare to compares unlike things, whereas compare with compares like things.
Rule 2: Compare to is used to stress the resemblance. Compare with can be used to show either similarity or difference but is usually used to stress the difference.
There is a difference between compare to and compare with; the first is to liken one thing to another;
the second is to note the resemblances and differences between two things.
Each
This question tests one use of "each" which most of us ignore. The traditional rule still holds true i.e. "the subject of a sentence beginning with each is grammatically singular".
But there is another rule which says that:
When each follows a plural subject, the verb and subsequent pronouns remain in the plural:
e.g. the apartments each have their own private entrances (not has its own private entrance)
Three cats each eat ...
Three cats, each of which eats ...,
In 1, each is postpositive Adj, whereas in 2, it is distributive determiner.
e.g.
Television can be superficial, as when three major networks each broadcast exactly the same.
Adverb clause of manner with temporal adverb clause:
Television can be superficial, as [TV is superficial] when three networks each broad cast the same.
------------------------------------------------------------------------------------------------------------
quote:
Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.
(A) superficial such as when each of the three major networks
(B) superficial, as can sometimes occur if all of the three major networks
(C) superficial if the three major networks all
(D) superficial whenever each of the three major networks
(E) superficial, as when the three major networks each
First of all, each, if it's a pronoun (as it is in A), is singular. In fact, each is almost always singular, but there's at least one exception, which we will see in just a minute. So, A can be faulted for using a plural verb, broadcast, with a singular subject, each. What I really like about A is that it uses such as, which we use to give examples. All the other incorrect answer choices use words that mean something different from for example.
The best answer, E, maintains the same meaning as A, and corrects the subject/verb agreement problem. Please note that one of the accepted meanings of as is for instance, and with this meaning, as is an adverb and can therefore be followed by parts of speech other than simply nouns.
B is not only awkward, it also incorrectly uses if in the subordinate clause connected with can in the main clause. I think this is the part that is confusing people (it certainly is what has confused TestMagic students in the past), so let's flip the sentence around to see a bit more clearly that it's not correct to use if with can: If all of the three major networks broadcast the same statement, television can be superficial.
This sentence should read:
If all of the three major networks broadcast the same statement, television will be superficial.
In other words, it's not correct to use can after if (in the context of what we've been talking about). Let's look at a simpler example:
If the temperature drops below 0 degrees celsius, distilled water can or will freeze.
Please post back with questions if you need clarification on this. Finally, it's better to use each than it is to use all, since each network is operating independently--all implies that the networks were working together.
That Vs Which
Most often than not, in GMAT, which would be preceded by a comma in the sentence.
e.g. Get me the book, which is mine. Which is used to qualify the book i.e. which is mine. There may be many books in the room, but I want my book.
'Which' should always refer to a noun. E.g. Get me the book, which is mine. So, 'which' here refers to the noun 'book'.
- Which should apply to things
-
The other thing--which must replace a noun, not a sentence or idea.
e.g. Sales of United States manufactured goods to non-industrialized countries rose to $167 billion in 1992, which is 14 percent more than the previous year and largely offsets weak demand from Europe and Japan.
- which is 14 percent more than the previous year
- which is 14 percent higher than it was the previous year
- 14 percent higher than the previous year's figure
- an amount that is 14 percent more than the previous year was
- an amount that is 14 percent higher than the previous year's figure
B is incorrect, because which should refer to a specific noun in the preceding clause. That noun does not exist ( Rise of sales). So, it is replaced by an amount that is 14 percent higher …
So, E is the correct answer (Similar to the UFO example in princeton)
That is a restrictive clause while which is a non restrictive clause.
After people study GMAT sentence correction for a while, they may ask about the difference between that and which.
But first, a testmagic tip: GMAT almost always (I say almost always because I've seen two questions that did not follow this rule, but the rule was violated in all five answer choices) wants you to put a comma before which. In other words, if you see which without a comma before it, it's probably wrong. After this explanation, you should understand why, but for those of you who want only the most important information, this is what you need to know.
An Example
Both of these sentences are correct in GMAT land:
- which is 14 percent more than the previous year
- Please go into the room and get me the big book, which is mine.
-
Please go into the room and get me the big book that is mine.
Yes, in GMATland, these two sentences have two different meanings.
Both of the following sentences would be incorrect in GMAT land:
- X Please go into the room and get me the big book which is mine. X
-
X Please go into the room and get me the big book, that is mine. X
Notice the commas--that's what makes all the difference.
The Explanation
Okay, we have in English this weird idea that we need to use different grammar in an adjective clause (a.k.a. relative clause) depending on whether the information in the adjective clause is necessary to specifically identify which noun we are referring to.
For example, imagine you have one sister, and you are telling a friend that your sister is coming to visit you. Since this person is your friend, we can presume that he knows that you have only one sister.
You utter a sentence like this to your friend in GMATland:
-
"My sister, who just graduated from college, is coming to see me."
In GMATland, since your friend (we presume) knows you well and knows that you have only one sister, this extra bit of information is considered unnecessary to identify which sister it is you are talking about. It is a sort of "by the way" information--"My sister is coming to see me, and oh, by the way, she just graduated from college."
Now imagine you have two, three, or even more sisters. Let's imagine that one is a college professor, another is a webmaster, and this one who is coming to visit you just graduated from college. If you're talking to your friend, and you say only "my sister," and you do not mention her name, your friend might not know which sister you are talking about. So you add that extra bit of information--my sister who just graduated from college--to identify which sister it is you are referring to.
In this situation, we have just correctly employed a very important grammar rule. Read on.
So, if the person you're talking to, or the person who's reading what you've written, needs that extra bit of information to know which noun you're referring to, we say that that extra information is non-restrictive. This word doesn't really describe the function clearly, so many teachers say that this information is "extra."
On the other hand, if you need that information to know which noun you are talking about, we say that the information is restrictive. Again, this word is not really a good choice for clarity, and many teachers use the term "necessary information" instead.
Finally, just to make English a bit more difficult, we have a rule that says we should use a comma before or after "extra information clauses and phrases," but not with "necessary information clauses or phrases." The idea here is that the comma represents the slight pause in speech or change in intonation that a native speaker might use when making such an utterance.
I should point out that both that and which are relative pronouns, i.e., they are grammatically the same, but their meanings are slightly different.
Now, let's return to our original example sentences:
- Please go into the room and get me the big book, which is mine.
In this sentence, the clause which is mine is "extra" because the information "the big book" is enough to identify which book it is that you want. We can assume that there is only one big book in the room.
- Please go into the room and get me the big book that is mine.
In this sentence, the clause that is mine is "necessary" because the information "the big book" is NOT enough to identify which book it is that you want--it is probably the case that there are several big books in the room, so I need to add the information "that is mine" to identify which book it is that I want.
More Examples
A few more examples may help:
-
-
I met with Bill Clinton, who is a lawyer.
The name Bill Clinton is enough to identify which person I'm talking about--who is a lawyer is therefore extra information.
-
I met with the man who is a lawyer.
In this case, "the man" is not enough information to identify which person I'm talking about--who is a lawyer is therefore necessary information.
- The Sun, which is the only star in our solar system, is the source of heat for Earth.
Again, the name "the Sun" already clearly identifies the noun; therefore, the information in the adjective clause "which is the only star in our solar system" is extra.
- The star that is at the center of our solar system is called what?
In this case, since we don't have a name here, we don't know which star it is that we are referring to. Therefore, the information in the adjective clause "that is at the center our solar system" is necessary.
- The Sun, which is the only star in our solar system, is the source of heat for Earth.
A good rule to learn is that which requires a comma before it. If you're not sure about why the comma is necessary, please see this post.
However, GMAT is very tricky at times, and can of course create a question in which this rule does NOT apply. In fact, I've seen a question that used which without a comma, but ALL the answer choices violated the rule. I.e., none of the answer choices used that; they all used which without a comma.
Here's an example of what I mean:
Lucise in San Francisco is a place which anybody can visit.
(A) which anybody can visit
(B) which any person could visit
(C) which no person could not visit
(D) which, if they wanted to, any person could visit
(E) which any person could visit if they so desired
I know some of you will think that this sentence is terrible, but the whole point of GMAT sentence correction is that we must choose the best answer, NOT the perfect answer.
The use of being
People who study for GMAT for a while quickly learn that being is usually wrong.
So I'm guessing you already know that being in an answer choice is wrong more often than it is right.
This is a good strategy to get you started, but to get over 700 on the GMAT, you really need to know some of the finer points of GMAT Sentence Correction that relate to the use of the word being.
There are at least two different situations in which being is often the right answer.
Here is the first example of when being is correct:
-
When the grammar requires it.
Yes, I'm trying to simplify things here, but the idea is this--many ideas can be expressed in more than one way. For example, I can say:
I'm afraid of being late.
I'm afraid that I'll be late.
Each has its own emphasis, but the point is that these two structures exist. (If I know my members here, I know that they will have questions about the difference, but please, let's start a separate thread for this.)
Whether we can express ideas in one or more structures is really related to the word used; in other words, it is idiomatic.
But some idioms allow only one structure. For example:
In addition to being one of the first restaurants to combine Mediterranean and American tastes, Chez Panisse in Berkeley is also one of the Bay Area's most established restaurants.
The idiomatic structure in addition to does not have a counterpart that uses a subject and a verb, so our only option here is to use being, which is grammatically a noun, but is derived from a verb.
-
with + NOUN + being + NOUN COMPLEMENT
The second example of when being is correct is shown in this example:
There are many reasons to get an MBA, with increased career prospects being the most important for many MBA applicants.
Technically this part here:
with increased career prospects being the most important for many MBA applicants
is an absolute phrase, but I think it's also helpful just to memorize the pattern:
Framed by traitorous colleagues, Alfred Dreyfus was imprisoned for twelve years before there was exoneration and his freedom.(A) there was exoneration and his freedom
(B) he was to be exonerated with freedom
(C) being exonerated and freed
(D) exoneration and his freedom(C)
(E) being freed, having been exonerated
C is correct. The main thing here is that we do not have the best option available to us:
before he was exonerated and freed
The second best option would be:
before being exonerated and freed
Because v/s. In That: When ETS puts 'because' and 'in that' in a sentence, more often than not, 'in that' would be correct. 'In that qualifies' the previous sentence, while 'because' is just used to show a simple causal relationship.
Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.
- because they are composed of tissues such as tooth and bone
- because they are composed of tissues like tooth and bone that are
- because they are composed of tissues, like tooth and bone, tissues
- in that their composition , tissues such as tooth and bone, is
- in that they are composed of tissues such as tooth and bone, tissues
E is the correct answer.
Usual v/s. Is Usual: He is faster than is usual for any human being – Is correct.
He is faster than usual today – is correct
A Mercedes is more expensive than usual for a car – Incorrect
A Mercedes is more expensive than is usual for a car – Correct
When something is compared to a subgroup to which it belongs, is usual should be used. When something is compared to itself, usual is fine.
e.g. He is nicer than usual.
Can v/s. Could: If you are just assuming something, 'could' should be used.
e.g. Artificial intelligence emerged during the late 1950's as an academic discipline based on the assumption that computers are able to be programmed to think like people.
(A) are able to be programmed to think like people
(B) were able to be programmed to think as people
(C) can be programmed to think as people can
(D) could be programmed to think like people
(E) are capable of being programmed to think like people do
Could is used for: possibility (John could be the one who stole the money), condition (If I had more time, I could travel around the world), suggestion (You could spend your vacation here), polite request (Could I have something to drink?)
Like vs As
First of all, I should say that just about any GMAT grammar rule will have some exception. For this reason, I prefer not to refer to "English grammar rules" but to "GMAT patterns." As I'm sure you're aware, it's very difficult to give a pattern that applies in every case. I would say that generally speaking, your summary is good, but just to be sure, I want to restate:
Use like when you want to focus on two nouns;
Use as when you want to focus on two nouns doing two actions.
Another little trick is that "just as" can replace "in the same way that..."
Let's compare two very similar sentences that could cause confusion:
My Siamese cat moved across the floor just like a lion stalking its prey.
To me, this sentence stresses how two different cats are similar. I know this is confusing because we have a noun, "lion" and a participle "stalking," which would seem to indicate that we should use "as," but it's just not so. In this sentence, do you think we're tying to say
My Siamese cat moved across the floor in the way that a lion stalks its prey.
I don't think so...
My Siamese cat moved across the floor just as a lion stalks its prey.
This one sounds bad to me, I think because we are not explaining how the cat is moving. Furthermore, at some point, we are going to run into some ambiguity--"as" does also mean "at the same time," and I also think that the sentence above does sound a bit like two things are happening at the same time.
Let's look at a better sentence:
My Siamese cat moved across the floor just as a lion stalking its prey moves.
This one sounds very good to me; it explains how a my cat moved.
Furthermore, it has the same meaning as:
My Siamese cat moved across the floor in the way that a lion stalking its prey moves.
Like vs. Such As
Question: What's the difference between like and such as?
Example of the "mistake" that we make in everyday speech: Can you buy me some fruit like oranges or grapefruit?
How the GMAT Official Guide would explain this mistake: Using like in this answer choice mistakenly suggests that the utterer of the request does in fact not want oranges or grapefruit, but rather some other kind of fruit that is similar to oranges or grapefruit.
In normal English: In GMATLand, like means similar to, and such as means for example. Take a look at these examples:
-
Can you buy me some fruit like oranges or grapefruit?
In GMATLand, this sentence would mean that you do NOT want oranges or grapefruit; instead, you'd prefer some fruit similar to oranges and grapefruit. For example, you may want pomelo, lemons, or limes. Yes, I know this sounds a little crazy, but our goal is to understand what GMAT is looking for, not what is "correct" English.
-
Can you buy me some fruit such as oranges or grapefruit?
Yes, this is what we're supposed to say in GMATLand -- oranges and grapefruit are examples of the type of fruit we want.
- I would like you to buy such fruit as oranges and grapefruit for me, if you don't mind.
This is simply a variation -- notice how such and as are separated. Separating the two elements tends to make this pattern a bit harder to see.
Not/But vs. Rather than
The key here is to realize that not... but... is conjunction. We use conjunctions when we want to join things that are "linguistically equivalent." Help much? No, probably not.
How about some examples?
Pucci is not a dog but a cat.
Not Todd but Taka will be studying with us today.
I not was sad but happy to learn that Megumi was moving to Paris for a better job.
You should notice that the words in bold are "linguistically equivalent," or, as we say in class, "parallel." Now compare one of these sentences if I try to use rather than:
Pucci is a cat rather than a dog.
Doesn't this sentence sound crazy? It should; the meaning is all wrong. Now, let's look at a similar sentence, one in which rather than is okay:
I want a cat rather than a dog.
This sentence is okay because we are expressing a preference for one thing over another thing.
I need X, not Y = I need X but not Y = I need not Y but X
"I need X rather than Y" does not connote "I need not Y", it just tells your preference.
Use of Consider: When 'consider' means 'regard as', 'as' should not be present with 'consider' in the sentence. Consider must directly be followed by the sentence without an infinitive like 'to be' etc.
Example: Some students of literary criticism consider the theories of Blaine to be a huge advance in modern critical thinking and question the need to study the discounted theories of Rauthe and Wilson.
to be a huge advance in modern critical thinking and question
as a huge advance in modern critical thinking and question
as being a huge advance in modern critical thinking and questioned
a huge advance in critical thinking and question (When consider means regard as, no need of as)
are a huge advance in modern critical thinking and questioned
Example 2:
Critics consider correction facilities to be an integral part of communal system. - Incorrect
Critics consider correction facilities an integral part of communal system. – Correct
BECAUSE v/s. ON ACCOUNT OF: On GMAT, 'Because' is preferred over 'on account of'. This is because 'because' can introduce an entire subordinate clause in the sentence (Golden crab is not fished, on account of living… - is not correct). Golden crab is not fished, because it lives… - is correct
CHIEF of WHICH v/s. CHIEF among which:
Jamieson's proposal was rejected for several reasons, the chief among which was cost.
(A) the chief among which was cost
(B) among which the chief was its cost
(C) the main one was cost
(D) the chief reason of which was its cost
(E) the chief of which was cost
chief means main or principal, and all three words mean the top one. And when we refer to a member of a group, we use of. For example, if we want to name our best friend, we'd say He is the best of my friends, but not He is the best among my friends.
Now, run these through your head to see how they sound:
- The main reason of all the reasons.
- The main reason among all the reasons.
I think the first sounds better and is more precise.
PRACTICE v/s. PRACTISE:
Practise is a verb and practice is a noun. I practise piano is correct. Also, I had my piano practice for the day is correct.
The doctor practised for 20 years; his brother a lawyer had a 2 year practice.
EACH v/s. EVERY:
Each refers to '2 times', every refers to 'More than 2 times'
The dog has bitten my younger son twice, and each time, he has had to be sent to his kennel.
each time, he has had to be sent to his
every time, it has had to be sent to his
each time, it has had to be sent to its
every time, it has had to be sent to its
each time, he has had to be sent to its
'Each time' because it has bitten only twice. The use of the pronoun "he" is unclear here - does it refer to the dog or to the son? In fact, tracing our way back along the sentence, we find that we come across the word "son" before we come across the word "dog", which rather implies that it is the son who owns, and is sent to, the kennel.
The way to get round this ambiguity is to use "it" followed by "its" (no apostrophe!). This limits the choices to (C) and (D). The only difference between these options is the fact that one uses the word "every" and the other uses the word "each". Since these refer to the two times that the dog bit the son, we shouldn't use "every" (that refers to three or more times). The correct option is therefore (C).
Economic v/s. Economical:
Economic means "having to do with the economy or the study of economics."
Economical means "careful or prudent in managing finances, money- saving."
The supply of oil being finite has become an economical and political consideration of the first magnitude for all modern industrial nations.
(A) The supply of oil being finite has become an economical
(B) The finite supply of oil has become an economical
(C) That the supply of oil is finite has become an economical
(D) The supply of oil being finite has become an economic(E)
(E) That the supply of oil is finite has become an economic - OA
Due To
"Due to" means "caused by" It should only be used if it can be substituted with "caused by". It does not mean the same thing as "because of."
Incorrect: The game was postponed due to rain.
Correct: The game was postponed because of rain.
Correct: The game's postponement was due to rain.
Neither … Nor
Neither the prosecutor's eloquent closing argument nor the mountains of incriminating evidence were able to convince the jury to find the defendant guilty.
In neither … nor sentences, the verb has to agree with the subject following nor - in this case mountains, which is plural.
Likewise in either .. or sentences, the verb must agree with the subject following or. When you see .. neither .. or .. nor in a sentence, see if it fits this sequence
Neither (A or B), nor C !!! also, not (A or B), nor C is fine too.
So [adjective] as to [verb]
Correct: Her debts are so extreme as to threaten the future of the company
"So as" is never correct on the GMAT
Incorrect: He exercises everyday so as to build his stamina
Correct: He exercises everyday in an effort to build his stamina
Not To Use:
-
Any Sentence construction with 'preposition + noun + participle'
e.g. With child-care facilities included (with – preposition, child-care – noun, included – participle)
Infinitives like 'to include', 'to implement' etc. are wrong on GMAT. Instead use, 'implementing', 'including' (Which are known as Gerunds) etc.
A Gerund is a noun formed from a verb i.e. Overcoming the GMAT is a great achievement. infinitives are usually formed to retain the integrity of the idiom which is used or to keep a sentence in parallel
-
Hopefully, is almost always wrong.
Charlotte Perkins Gilman, a late nineteenth-century feminist, called for urban apartment houses including child-care facilities and clustered suburban houses including communal eating and social facilities.
A) including child-care facilities and clustered suburban houses including communal eating and social facilities
B) that included child-care facilities, and for clustered suburban houses to include communal eating and social facilities
C) with child-care facilities included and for clustered suburban houses to include communal eating and social facilities
D) that included child-care facilities and for clustered suburban houses with communal eating and social facilities
E) to include child-care facilities and for clustered suburban houses with communal eating and social facilities included
First, we can eliminate all the answer choices that use with communal eating and social facilities included or any other structure that follows this pattern:
preposition + noun + participle
This pattern is almost always wrong on the GMAT, and is certainly wrong in this question. This eliminates C) and E).
A) is ambiguous--is clustered suburban houses parallel with child-care facilities or with urban apartment houses? We need to repeat for to be sure that clustered suburban houses is parallel with urban apartment houses.
Now we're left with B) and D).
Now, the only difference between B and D is the infinitive to include, which GMAT considers unidiomatic.
That leaves us with D).
- Watch for the prepositions (to, the, of, at, for, on, in, about, etc.,) changing among the answer choices. This usually implies an Idiomatic problem, if not a Parallel Construction problem.
- Note that Idiomatic problems are often shorter than many of the other types of questions. Not in all cases, but as a general rule, if the problem seems much shorter than other problems, it is probably Idiomatic.
- Check out the verb immediately before the changing preposition. Which verb-preposition combination sounds worst? Eliminate answer choices that sound just awful, ex. He forbids me of going. The correct answer would be He forbids me to go.
- Which verb-preposition combination sounds best? Choose that as your answer.
