Choose the option that best completes the gap(s).

Long after everyone _____ the hall, Obi still sat inside.

Answer Details

The best option to complete the sentence is "had left." This is because the sentence is in the past tense and refers to an action that happened earlier than another action in the past. The word "long" also implies that a considerable amount of time had passed, further indicating that the action of leaving took place before Obi's continued sitting in the hall. Therefore, the past perfect tense "had left" is most appropriate to show that the leaving occurred before Obi's continued sitting.
