Question
Who (invent) ______the washing machine?A.inventB.inventsC.InventedD.has invented
Solution
The correct answer is C. "invented"
Here's why:
The question is asking about a past event, specifically, the invention of the washing machine. Therefore, the verb tense that should be used is the simple past tense.
In English, when we form a question about a past event, we use the past tense of the verb. So, "Who invented" is the correct form.
The other options are incorrect because they use different tenses or forms. "Who invent" and "Who invents" are present tense, and "Who has invented" is present perfect tense.
