    This is a question that can be resolved just on the basis of the beginnings of the options. In the given sentence, you have the introductory phrase Almost like clones in their similarity to one another. The reciprocal pronouns ONE ANOTHER require a plural referent, and in this sentence that plural referent must be the subject. Furthermore, this plural subject must be one that the introductory phrase can logically modify.

    1. In option A, the subject is HOMOGENEITY, which is singular and is not logically modified by the introductory phrase.

    2. In option B, the subject is SPECIES, which can be either singular or plural, but here is singular and is followed by a singular verb. Moreover, there is no logical connection between SPECIES and the introductory phrase.

    3. In options C and D the subject is again HOMOGENEITY, so the objections that apply to option A also apply here.

    4. Since option E refers to plural MEMBERS, and since it is these MEMBERS that are similar TO ONE ANOTHER, this is the correct answer.

    Only LIKE things may be compared.
    APPLES may be compared to other APPLES.
    APPLES may not be compared to COMPUTER KEYBOARDS.

    like means similar to.
    homogeneity is the condition of being similar.

    A: Almost like clones, the...homogeneity
    C: Almost like clones, the homogeneity
    D: Almost like clones, homogeneity
    Conveyed comparison:
    THE CONDITION OF BEING SIMILAR is almost similar to CLONES.
    This comparison is nonsensical.
    Eliminate A, C and D.

    B: in their similarity, the cheetah species is
    Here, their (plural) does not agree with species (singular).
    Eliminate B.

    The correct answer is E.

    gmatguru,
    I don't really get this part...

    I guess,here,the antecedent of pronoun their should be the preceding noun clones -- NOT the following noun species (singular). whereas, the antecedent of pronoun its is the corresponding preceding noun species (singular).

    isn't it ?

    please let me know your thoughts!

    A clone is an exact copy created in a laboratory.
    X and Y exhibit similarities if X and Y are not exact copies of each other but have traits IN COMMON.
    Thus, clones -- which are exact copies of each other -- CANNOT exhibit similarities.

    A pronoun in an introductory modifier can serve to refer to the subject of the following clause.
    SC28 in the OG12:
    Building on civilizations that preceded THEM in coastal Peru, THE MOCHICA developed their own elaborate society.
    Here, them serves to refer not to civilizations (the preceding plural noun) but to the Mochica (the subject of the following clause).

    The OA to SC132 in the OG16:
    Almost like clones in their similarity, members of the cheetah species are especially vulnerable to disease.
    Since clones cannot exhibit similarity, the only logical referent for their is members (the subject of the following clause).
    The portion in red implies the following:
    In THEIR similarity to one another, MEMBERS of the cheetah species are almost like clones.
    Here, their serves to refer to members of the cheetah species.
    Conveyed meaning:
    Members of the cheetah species are so similar to one another that they are almost like exact copies created in a laboratory.

    B implies the following:
    In their similarity to one another, the cheetah species is almost like clones.
    Here, their (plural) does not agree with species (singular).
    Eliminate B.

    gmatguru,
    while I understand your above explanation, but what I don't get is:

    how we can interpret it in this way ?

    because, this complete PHRASE "Almost like clones in their similarity to one another" is followed by comma. so, how we can consider a part of this PHRASE -- in their similarity to one another -- with the portion of the SC after comma ?

    can you please help ?

    p.s: as for ERROR in B, will the following constitute a valid ERROR ?

    CLONES means many individuals, whereas the cheetah species is A GROUP. so we can't compare many individuals with A GROUP. thoughts ?

    Almost like clones in their similarity to one another, members of the cheetah species are especially vulnerable to disease.

    The phrase in red is an ADJECTIVE modifying members of the cheetah species.
    Question:
    What KIND of members?
    Answer:
    Members ALMOST LIKE CLONES.

    The phrase in blue is an ADVERB modifying the phrase in red, expressing HOW members of the cheetah species are almost like clones.
    Question:
    HOW are members of the cheetah species almost like clones?
    Answer:
    In the members' similarity to one another.

    Quote:

    CLONES means many individuals, whereas the cheetah species is A GROUP. so we can't compare many individuals with A GROUP. thoughts ?
    This line of reasoning seems valid.
