Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

In the sentence "When Shakib Khan's movie came to town, all the tickets ---- sold out far in advance," we need to choose the appropriate verb form to indicate the past tense. The options include "had," "have," "were," and "had been," and the correct answer is "were."

The key to selecting "were" lies in understanding the context and the grammatical structure. The phrase "came to town" indicates a specific moment in the past. The subject is "all the tickets," which is plural, and the verb needs to agree with this subject.

Using "were" is appropriate here as it is the simple past tense of the verb "to be," linking the subject to the state of being sold out at the time the movie arrived. This suggests that at that past moment, the tickets were already sold out, conveying a straightforward and direct relationship between the two events.

In contrast, the other options do not fit grammatically or contextually. "Had" and "had been" imply a perfect tense that suggests an action completed before another past action, which is overly complex for this structure. "Have" implies a present tense, which does not align with the past context. Thus, "were" is the clearest and most effective choice to complete the sentence accurately.
