Explanations:In English grammar, the correct use of verb forms and types is crucial for conveying the intended meaning accurately. The question at hand involves the correct use of the simple past tense to describe a completed action in the past. The sentence "Local police arrested the bank robber yesterday" requires a verb in the simple past tense to match the time frame indicated by "yesterday."
The subject of the sentence is "local police," which is a collective noun. Collective nouns can be treated as singular or plural depending on the context. In this case, "local police" is treated as a singular entity performing a single action, so the verb "arrested" is in the simple past tense and agrees with the singular subject.
Option A, "have been arrested," is incorrect because it uses the present perfect tense, which is used to describe actions that have relevance to the present. Since the sentence specifies "yesterday," the action is completed and does not have ongoing relevance to the present.
Option B, "was arrested," is incorrect because it uses the passive voice. The passive voice is used when the focus is on the receiver of the action rather than the doer. In this sentence, the focus is on the action performed by the local police, so the active voice is more appropriate.
Option C, "arrested," is the correct choice because it uses the simple past tense, which correctly describes a completed action in the past. The verb "arrested" agrees with the singular subject "local police" and matches the time frame indicated by "yesterday."
Option D, "None of the above," is incorrect because one of the other options (Option C) is correct. The sentence requires a simple past tense verb to describe a completed action in the past, and "arrested" fulfills this requirement.
Understanding the correct use of verb tenses and voice is essential for constructing grammatically correct sentences. The simple past tense is used to describe actions that were completed at a specific time in the past, and the active voice is used when the focus is on the doer of the action. In this case, the sentence "Local police arrested the bank robber yesterday" correctly uses the simple past tense and the active voice to describe a completed action in the past.
