Hi !!
Andrew / have / what hobbies
What hobbies does Andrew have ?
When using the present tense, you must use the auxiliary 'do' or 'does' (3rd pers. sing. ) + the base form of the verb for interrogative and negative forms.
interrogative noun(what, where, when ...) + do/does + subject + base form of the verb + ?
For example in the negative form, it would be ==>
Andrew doesn't (does + not) have hobbies.
Subject + do/does + not + Base Form (don't /doesn't in shortening form)
In the simple present form, ===>
Andrew has hobbies.
