CHOICES

Choice-A

"Mark slept the entire day; his friend felt that the entire day had been wasted by him."

The sentence lacks parallel structure. The first part is in past tense ("Mark slept the entire day"), but the second part switches to present perfect tense ("had been wasted").

Wrong No change

7

Choice-B

"Mark slept the entire day; his friend felt that he was wasting the entire day."

The sentence is incorrect. "He was wasting" uses the past continuous tense, which shows an action in progress. Here, the sentence needs a completed action, so this tense is not appropriate.

Wrong he was wasting the entire day

8

Choice-C

"Mark slept the entire day; his friend felt that the entire day will have been wasted by him."

The sentence is incorrect because it uses "have been" instead of "had been." This doesn’t maintains the proper past tense consistency.

Wrong the entire day will have been wasted by him

9

Choice-D

"Mark slept the entire day; his friend felt that he had wasted the entire day."

The sentence is correct because it maintains consistency in verb tense. "Slept" and "had wasted" are both in the past tense, creating a coherent timeline. It accurately describes Mark’s action (sleeping) and his friend’s perception (feeling that Mark had wasted the day).

Correct he had wasted the entire day
