Question

Which sentence correctly uses the past perfect tense?



Carl bought a ticket three weeks in advance.


Carl has packed three suitcases for his trip.


Carl will have lost his map by the end of the trip.


Carl had asked his mother’s permission before he left town.

Answer 1

"Carl had asked his mother’s permission before he left town."

This correctly uses the past perfect ("had asked") to show an action completed before another past action ("left").
