Question

The given sentence is divided into four segments. Identify the segment that contains a grammatical error.

When I returned to the office, / no work was left / as my friend Rahul / has done everything.

Accepted Answer

**Solution:**

1. The sentence is in the past tense, indicated by "When I returned to the office".

2. The phrase "has done everything" is in the present perfect tense, which is incorrect here because it refers to an action completed before the past event of returning to the office.

3. According to the sequence of tenses rule, when two actions occur in the past, the earlier action should be in the past perfect tense.

4. Therefore, "has done everything" should be changed to "had done everything" to correctly reflect that the friend's completion of work happened before the speaker returned.

5. The other segments are grammatically correct.

**Correct sentence:**

_When I returned to the office, no work was left as my friend Rahul had done everything._

**Answer:** Segment 3 ("has done everything") contains the grammatical error.
