Hi!

An idiom is a common expression or grammatical structure in English. You might hear idioms described elsewhere as a “saying”—for example, “as easy as pie”—but on the GMAT, you won’t see these as often. Instead, you’ll encounter more everyday constructions and have to decide which one is correct in English.

For example, which one of these sentences is correctly phrased?

Henry graduated from college.

Henry graduated of college.

The first one is correct: You don’t graduate “of” school. You graduate “from” school. There’s no special grammatical reason that this is the case, other than that that’s simply the way we talk about graduation in English (using the preposition “from” rather than the preposition “of,” that is). This is an example of how you’ll encounter idioms on the GMAT: There’s no specific grammar rule to follow, but an idiomatic expression will need to be corrected simply because it’s not used in English.

Focus on the words in all caps in your quote. Those are the ones that are actually part of the idiom. The verb 'exist' isn't the important part; you could replace it with a different verb, as long as it's in the same form as the verb in the examples.

So if you want to write these examples as a rule, you might start by writing, '(someone) AGREES THAT something happens' = correct.

On the other hand, '(someone) AGREES something happens (no that)' = suspect.
