Hi Andriana, All your answers are wrong for the same reason - the auxiliary verb "do" is missing. e.g. How does Alex go to work? If you look in your grammar books for information about how to form open questions in the present tense, they will explain the use of "do / does". For example, look up page 4 of English Grammar in Use, by R Murphy.

Put the question to each sentence. 1) Alex goes to work by car. How does Alex goes to work? 2)Mary lives in my street. Were does Mary lives? 3)They have dinner at 6. When do they have dinner? 4) My brother plays tennis on Fridays. When does my brother plays tennis? 5)Our mother drinks coffee in the morning. What does our mother drinks in the morning?
