Identify the part of the sentence that contains an error.
The guests from Lucknow / waited on the platform for an hour / because their porter / did not came back with the trolley.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → did not came back with the trolley
The sentence says “did not came”. This is wrong. “Did” already shows the past time. The verb after “did” is always in its base form. So “came” must be come.
Option 1: The guests from Lucknow — No error.
Option 2: waited on the platform for an hour — No error.
Option 3: because their porter — No error.
Option 4: did not came back with the trolley — Error. “did not came” should be “did not come”.
Corrected: The guests from Lucknow waited on the platform for an hour because their porter did not come back with the trolley.
