Fill in the gap with the most appropriate option from the list following the gap.

The president of the union _____ for the airport by the time the riot started?

Answer Details

The most appropriate option to fill in the gap is "was leaving." This is because the sentence is in the past tense, and the phrase "by the time the riot started" indicates that the leaving action had already occurred before the riot. "Was leaving" is the past continuous tense, which fits this context. The other options do not fit because "would have left" is the conditional perfect tense and implies that the leaving action did not actually happen. "Is about leaving" is present continuous tense and does not fit with the past tense of the rest of the sentence. "Has left" is present perfect tense and also does not fit with the past tense context of the sentence.
