The police claim that a number of stolen cars _____ recovered?
Answer Details
The best option to complete the sentence is "have been." This is because the subject of the sentence is "a number of stolen cars," which is plural, and the verb "recovered" should agree with the subject in number. "Have been" is the plural form of the auxiliary verb "have" used with past participle "been" to form the present perfect tense, which is appropriate for the past action that has relevance to the present moment. Therefore, the complete sentence should read, "The police claim that a number of stolen cars have been recovered."
