Expert's Global Official Explanation:

Comparison + Parallelism + Meaning + Verb Forms

    • Comparison must always be made between similar elements.
    • “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.

A. Trap. This answer choice incorrectly compares the clause “an animal’s immune system deploys antibodies…” to the noun phrase “a police officer who tracks…”; please remember, a comparison must always be made between similar elements. Further, Option A incorrectly uses “like” to compare the clause “an animal’s immune system deploys antibodies…” to the noun phrase “a police officer who tracks…”; please remember, “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.

B. Trap. This answer choice incorrectly compares the clause “an animal’s immune system deploys antibodies…” to the gerund (noun) phrase “the tracking of a criminal…”; please remember, a comparison must always be made between similar elements. Further, Option B incorrectly uses “like” to compare the clause “an animal’s immune system deploys antibodies…” to the gerund (noun) phrase “the tracking of a criminal…”; please remember, “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples

C. This answer choice incorrectly compares the clause “an animal’s immune system deploys antibodies…” to the noun phrase “a police officer who tracks …”; please remember, a comparison must always be made between similar elements.

D. Correct. This answer choice correctly uses “as” to compare the clause “an animal’s immune system deploys antibodies…” with the clause “a police officer tracks fleeing criminals…”.

E. This answer choice incorrectly compares the clause “an animal’s immune system deploys antibodies…” to the noun phrase “a police officer who tracks …”; please remember, a comparison must always be made between similar elements. Further, Option E incorrectly uses “as” to compare the clause “an animal’s immune system deploys antibodies…” to the noun phrase “a police officer who tracks…”; please remember, “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.
