Complete the sentence with the right verb. Where ... you yesterday?

{"options"=>["was", "were", "visited", "did"], "correct_answer"=>"were", "explanation"=>"This sentence is a question in the past tense. The question word 'where' is followed by the auxiliary verb 'were' because the subject of the question is 'you', which requires the plural form. 'Was' is used for singular subjects like 'I', 'he', 'she', or 'it'. 'Visited' is the main verb, not an auxiliary and doesn't fit the sentence structure. 'Did' is used to form questions in past simple for verbs that are not the verb 'to be'."}
