Question

Read the sentence. Most swimmers learn the crawl first because it was easiest. Which revision corrects the error in verb sequence? A. Most swimmers learn the crawl first because it was being easiest. B. Most swimmers learn the crawl first because it had been easiest. C. Most swimmers learn the crawl first because it will have been easiest. D. Most swimmers learn the crawl first because it is easiest.

Answer 1

I'm pretty sure it's D. 

Answer 2

The revision that corrects the error in verb sequence is "Most swimmers learn the crawl first because it is easiest." Option D is correct.

This is the sentence which has the correct verb tense. The first part of the sentence is in present tense so that the second one, in this particular case and context should also be in present tense. All the other options are incorrect because the verb sequence is not proper.
