question 8 of 10
which sentence uses parallel structure correctly?

a. animal testing has helped discover medicines, saves lives, and will make people healthy.

b. the death penalty is too expensive, it takes a long time, and criminals arent deterred.

c. texting while driving causes automobile accidents, a person to be distracted, and it is bad.

d. processed foods are bad for your lifestyle, your complexion, and your health.

Explanation:

Parallel structure requires consistent grammatical form for items in a list.

• Option A mixes verb tenses: "helped discover" (past), "saves" (present), "will make" (future), so it is incorrect.
• Option B uses inconsistent clause structures: the first is a predicate adjective phrase, the second is an independent clause, the third is another unrelated clause, so it is incorrect.
• Option C mixes noun phrases, infinitive phrases, and independent clauses, so it is incorrect.
• Option D uses consistent noun phrases ("your lifestyle, your complexion, and your health") to complete the parallel structure, so it is correct.

Answer:

D. Processed foods are bad for your lifestyle, your complexion, and your health.
