Question

The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer. I am / cleaning the sofa / when she called me.

• A. cleaning the sofa
• B. when she called me
• C. No error
• D. I am

Answer 1

Answer:

D. I am

• The sentence suffers from a tense mismatch. You are describing two actions that happened at the same time in the past, but the verbs are pointing in different directions: "When she called me" is in the simple past, establishing that the event already happened. "I am" is in the present continuous, which implies the action is happening right now. To fix this, the auxiliary verb needs to be changed to the past continuous to match the timing of the phone call.
