Question

read this sentence:
the faster you travel, the more slowly time passes, which means that time moved quickly when you are walking but more slowly when you are flying in an airplane.
which revision of the sentence uses parallel structure?
a. the faster you traveled, the more slowly time passes, which means that time moved quickly when you are walking but more slowly when you are flying in an airplane.
b. the faster you travel, the more slowly time passes, which means that time moves quickly when you are walking but more slowly when you are flying in an airplane.
c. the faster you travel, the more slowly time passing, which means that time moved quickly when you are walking but more slowly when you are flying in an airplane.
d. the faster you travel, the more slowly time passes, which means that time moved quickly when you were walking but more slowly when you are flying in an airplane.

Explanation:

Parallel structure requires consistent verb tenses. In the original sentence, the first part is in present tense ("travel", "passes"). Option B maintains this consistency with "moves" (present tense) for both "when you are walking" and "when you are flying" scenarios. Option A has a tense mismatch ("traveled" vs. "passes"). Option C has incorrect grammar ("time passing" instead of "time passes"). Option D has a tense mismatch ("were walking" vs. "are flying").

Answer:

B. The faster you travel, the more slowly time passes, which means that time moves quickly when you are walking but more slowly when you are flying in an airplane.
