TAKEAWAYS• A possessive antecedent of a pronoun is not preferred. Occasionally that construction is allowed. Do not think in terms of absolutes.
Most of the time, a subject pronoun (she, you, him) or an object pronoun (her, your, his) should not have a possessive noun as an antecedent.
Occasionally, that setup is okay, especially when, as here, there is only one logical noun referent.
Some of you have heard of this "possessive poison" rule.
It is not ironclad.Please read
this post of mine, here, in which I analyze a Manhattan question modeled on an official question.
In both questions, a possessive noun is allowed to be the antecedent of a subject pronoun.
• Idiom #1:
So X as to YCorrect: So [adjective] as toCorrect:
The courage of the Ukrainian people is so inspirational as to move seasoned diplomats to tears and to bring world leaders to their feet. Wrong: As [adjective] as to

I do think that you need to learn idioms; they show up in one-third of questions (or, depending on the volume, nearly one-third).
You do not need to learn 30,000.
Please, do not even try to do so.
I would learn the top 100.
The three I listed above are in that top 100.
MAGOOSH OFFICIAL ANSWER• Split #1: the idiom "so [adjective] as to" is correct, and the construction "as [adjective] as to" is idiomatically incorrect.
Choices (A) & (B) are incorrect on this split, and choices (C) & (D) & (E) are correct.
• Split #2: the idiom "fail to" is correct, and the construction "fail in" is incorrect.
Choices (B) & (E) are incorrect on this split, and choices (A) & (C) & (D) are correct.
• Split #3: there are two acceptable idioms involving the verb "distinguish":
→ one is
to distinguish P from Q (choices A and D have this correct);
→ the other is
to distinguish between P and Q (no choice has this correct).
It is incorrect to use
distinguish between with
from (choices B and E) make this mistake).
It is also incorrect to use "distinguish" + "and" without the word "between" (choice C makes this mistake).
• Split #4: Parallel structure
In either of the forms of the "distinguish" idiom, the P and Q must be parallel in structure.
Both can be gerunds, such as
selling and
collecting (choices C and D have this correct).
Both can be nouns, such as
sale and
profits—no answer choice has that construction.
It violates parallelism to have one gerund [verbING] and one [regular] noun — choices A, B, and E make that mistake.
• Split #5: only one choice has this issue, but notice the mystery pronoun in (E): who is the "he" mentioned in this choice?
Senator Crocker's name appears only in the possessive, and on the GMAT, [although a possessive antecedent is occasionally allowed to be referenced by a subject or object pronoun, if a grammatical and stylistically correct answer exists that does not pair a pronoun with a possessive antecedent, use that answer].
The only possible answer is (D).
