The following sentence has been divided into four segments. Identify the segment that contains a grammatical error.
After your insistence, / my sister / checked / a mailbox again.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 2 i.e. a mailbox again.
The use of "a" suggests that there could be any mailbox, but the context implies a specific mailbox that is being referred to repeatedly.
"The mailbox" is the appropriate article when referring to something specific, which in this case would be the mailbox the sister is checking
Hence, the correct sentence is:- "After your insistence, my sister checked the mailbox again."
