Can you explain why you choose B?

I choose E. However, you choose B and I am sure that you thought much about the same. Please share your thoughts with us.

Same thing goes with 'duongthang'. Could you guys please share your thoughts?

i narrowed down to D and E because of idiom "provide...for"
D "by mammals" i think is passive. even in B same problem is there
another problem in D is that "they" does not have clear reference

I haven't hit the chapter of Voice in MGMAT SC yet, but by concision alone, E looks to be the best option.

A: "in addition to how" awkward/wordy
B: "in the determination" (maybe; 2nd choice)
C: "and when they did" fragmented/awkward
D: "and how they were" fragmented/awkward
E: concise, grammatically correct

E

OA?

very hard

I think the idiom is "clue of something" not "clue of doing or in noun"

"to do" is prefered than "for doing"

so, IMO C

B. in the determination of how and when the islands of the West Indies were
colonized by mammals
C. to determine how mammals colonized the islands of the West Indies and when

D. for determining when the islands of the West Indies were colonized by mammals
and how they were
E. for determining how and when mammals colonized the islands of the West Indies
Answer:A/E
IMO E.

A - In addition to how, when - wierd; of determining - wrong
B - In the determination of; passive voice is unnecessary here
C - Even though it has used "to determine" correctly, THEY doesn't have a clear antecedent.
D - Same as above.
E - This should be the correct answer in my opinion.

What is OA?
