    Some anthropologists believe that the genetic homogeneity evident in the world's people is the result of a "population bottleneck"-at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.

    A at some time in the past our ancestors suffered an event, greatly reducing their numbers
    B that at some time in the past our ancestors suffered an event that greatly reduced their numbers
    C that sometime in the past our ancestors suffered an event so that their numbers were greatly reduced
    D some time in the past our ancestors suffered an event from which their numbers were greatly reduced
    E some time in the past, that our ancestors suffered an event so as to reduce their numbers greatly,

    D some time in the past our ancestors suffered an event from which their numbers were greatly reduced
    E some time in the past, that our ancestors suffered an event so as to reduce their numbers greatly,
    Option A:
    1.we need a connector 'that' after believe because the sentence is continuing to talk about the belief.
    2.Reducing is a VERB-ing modifier- Clause,Verbing modifies the preceding and makes meaning with subject of the preceding clause.Here "ancestors" is the subject of the preceding clause.Ancestors are reducing --is nonsensical ..Its the event.
    Option B:Correct
    Option C:so that--implies the ancestors suffered the event intentionally--which is wrong
    Option D:
    1.Misses 'at; prepostion before sometime.
    2.Modifier --from which their numbers were greatly reduced..implies that the event was reason..rather intended meaning is the result of event ..
    Option E:
    that incorrectly refers to some time in the past
    also misses prepostion

    Hope it helps!!

    (A) at some time in the past our ancestors suffered an event, greatly reducing their numbers
    (B) that at some time in the past our ancestors suffered an event that greatly reduced their numbers
    (C) that some time in the past our ancestors suffered an event so that their numbers were greatly reduced,
    (D) some time in the past our ancestors suffered an event from which their numbers were greatly reduced
    (E) some time in the past, that our ancestors suffered an event so as to reduce their numbers greatly,
    A COMMA + VERBing modifier is attributed to the SUBJECT of the preceding clause.
    In A, reducing seems to refer to our ancestors, implying that OUR ANCESTORS were greatly reducing their numbers.
    Not the intended meaning: our ancestors did not reduce their own numbers.
    The intended meaning is that an EVENT greatly reduced their numbers.
    Eliminate A.

    So that (in C) and so as (in E) imply PURPOSE.
    The result is a strange meaning: that our ancestors suffered for the PURPOSE of reducing their numbers.
    Not the intended meaning.
    Eliminate C and E.

    In D, which seems to refer to an event, implying that our ancestors' numbers were reduced FROM an event -- a nonsensical meaning.
    Eliminate D.

    The correct answer is B.

    Thanks for the great explanation. But i have a question. How to understand the sentence is continuing to talk about the belief? What does (-) indicate?

    oh another question. Can you please clarify the meaning of "as to"?

    Thanks again Smile

    Some anthropologists believe that the genetic homogeneity evident in the world's people is the result of a "population bottleneck"-at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.

    The highlighted sentence in bold starts with that..blah blah.This is a modifying clause.Remove this and you have the answer Smile

    Thanks a lot,Guru.
    I have 2 question?

    does "as to" indicate purpose?

    I am confused with the use of "The" in option A.

    Would you please explain?

    NB: you didn't see my PM Smile
