Complete the sentence below by filling in the blank with the grammatically correct form of the verb to show the proper sequence of past events.
Answer:Before the school inspector arrived yesterday, the principal 【had concluded】 the morning assembly.
Answer
had concluded (or had finished / had ended / had dismissed)
The sentence establishes a sequence of two past actions anchored by the time marker 'yesterday'. Because the principal's action was completed prior to the inspector's arrival, the past perfect aspect (auxiliary 'had' followed by the past participle form of the main verb) must be used.
