    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?

    One more vote for E-Obvious.

    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

    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?

    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
