For D and E, you have an clause before it meaning, the -ing form can modify it grammatically. Also, for D, X and Y look parallel. So what is wrong the modifier?

Also, for B, why would you reject it? X and Y are both in the -ING form and thus parallel.

On what grounds are those answers rejected?

(A) a compilation of all medicine after Hippocrates and summarizing as well
Compilation is not parallel with summarizing.
• Medicine cannot be compiled in the way this sentence intends. Medical knowledge can be compiled.
VOCABULARY: The verb "to compile" refers to information, data, scores, computing, etc.
• Idiom is wrong: X . . . and Y as well (NO)


(B) a compilation of all medicine following Hippocrates and also summarizing
Parallelism: Identical to A's problems
• Medicine / medical knowledge: Identical to A's problems
• Idiom is wrong: X . . . and also Y (NO)


(C) a compilation of all medical knowledge since Hippocrates as well as a summary of
CORRECT

(D) compiling all medicine from Hippocrates forward and also a summary of
Parallelism: Compiling is not parallel with summary
• Medicine / medical knowledge: Identical to problems in A and B
• Idiom is wrong: X . . . and also Y (same problem as B has - NO)

Another idiom is wrong: "from Hippocrates forward."
The correct idiom is "from that time forward." (Similar to "from this day forward.")
History moves forward from a time, not from a person.


(E) compiling all the medicine done since Hippocrates as well as his own summary of
Parallelism: Identical to D's problem.
• S/V is not idiomatic: medicine is not "done," and certainly not in this context.
The meaning should convey "medical knowledge since Hippocrates['time]"
• Pronoun phrase redundancy: "his own." The last part of the prompt already tells us "was himself working on."

albertziade , see my explanations above.

In B, which words, X and Y, seem parallel to you?

With respect to D and E, I address your modifier question below.
The decisive issues, however, are parallelism and idiom construction.

Parallelism, Idiom

GMAT writers love to test parallelism.

The correct idiom is X as well as Y or X and Y.

Only Answer C contains the correct idiom plus parallel X and Y

A) Noun (compilation) X . . . Present Participle (summarizing)(Verb-ING) Y as well

B) Noun (compilation) X . . . and also Present Participle (summarizing)(Verb-ING) Y

C) Noun (compilation) X . . . as well as Noun (summary) Y

D) Present Participle(compiling)(Verb-ING) . . . and also Noun (summary) Y

E) Present Participle (compiling)(Verb-ING) . . . as well as . . . Noun (summary) Y

Your question about the modifier

albertziade wrote:

I assume you mean "it" as an acceptable pronoun for the book, such that "compiling" could modify the book?

Here is the sentence I think you imagine:

Pedanius Dioscorides, a first-century physician and botanist, presented detailed information about medicinal materials and practices in his five-volume book De Materia Medica, compiling all medical knowledge since Hippocrates as well as summarizing new experiments that Dioscorides was himself working on.

Does "compiling all medical knowledge . . ." modify the book, or the author?
If this sentence replaced C, and the other answers remained the same, you would choose this one.
Compiling and summarizing are parallel.
The idiom X as well as Y is correct.

If you have to choose between that hypothetical sentence and C, as happens sometimes on very hard questions?
Choose C. A person cannot be a compilation or a summary.
In Answer C, the nouns make it clear that the modifying phrase (after . . . "Medica") modifies the book

Hope that helps. :-)
