Question

Correct the underlined part of the sentence, if necessary:

Diane hasn't been at work yesterday.

• A. didn't be
  
• B. hadn't been
  
• C. wasn't
  
• D. no error
  

Answer 1

Answer: (C)

wasn't

Option D: The underlined part 'hasn't been' is in present perfect tense.

The present perfect tense expresses an action that just happened, and not a past action 'yesterday'. Hence the underlined part is an error and needs to be corrected. Thus option D is wrong.

Option C: 'Wasn't' indicates a past action that happened in the past: 'yesterday'.

It agrees to the given sentence and forms a complete meaning. Hence option C is correct.

Option A: 'Didn't be' is grammatically incorrect. 'Be' does not follow 'do'. 'Do' refers to an action whereas 'be' refers to an existence. Both don't go together. Hence A is wrong.

Option B: 'Hadn't been' is in past perfect tense. It expresses an action that completed in the past, before another action happened in the past. The given sentence does not match this scenario.

Hence option B is wrong.
