Hi,
I have started studying the Idioms chapter from the Manhattan SC 4th edition.
I am having some trouble understanding the information given in this chapter.

Firstly, I want to know whether the usage given in this chapter for the words is the considered correct usage for that word.

For example: In the sentence “Her AID IN WALKING the dog was appreciated.”
Can I consider that "Aid in" followed by an "Ing" format will always be correct??

Also the sentence "She provides AID TO victims." is written as correct.
What I understood was that "Aid To" + noun is correct.
If my understanding here is correct then why is the sentence
"Her AID TO WALK the dog was appreciated." wrong?


A similar issue I am facing with "Agree that". I am unable to decipher the correct usage of "Agree that".

I had also seen the idioms list present in the third edition and in that list there were two forms of Agree given, "Agree to" and "Agree with".
But in this edition those forms are missing.

Could you please explain me how should I approach this chapter and overcome these issues so that I can gain maximum knowledge from it.

Thanks,
AS

"For example: In the sentence “Her AID IN WALKING the dog was appreciated.”

It's tricky to say that anything will ALWAYS be the case with idioms, but you should accept this construction as a general rule..

"Also the sentence "She provides AID TO victims." is written as correct.
What I understood was that "Aid To" + noun is correct.
If my understanding here is correct then why is the sentence
"Her AID TO WALK the dog was appreciated." wrong?"

"walk" is not a noun in this sentence..

"A similar issue I am facing with "Agree that". I am unable to decipher the correct usage of "Agree that"."

You would say "i agree that [some clause that indicates a statement you agree with]"..

"I had also seen the idioms list present in the third edition and in that list there were two forms of Agree given, "Agree to" and "Agree with".
But in this edition those forms are missing."

It sounds like you're asking when we use "agree to" and "agree with". You would say "agree to [verb that you are going to do]" and "agree with [some person or idea you agree with]"..

"Could you please explain me how should I approach this chapter and overcome these issues so that I can gain maximum knowledge from it."

Memorize. Make flash cards. Be sure you know how the GMAT uses each idiom correctly and what sort of incorrect versions show up in the wrong answer choices..
