What are these questions called?

“Which Emile Brontë novel…”

Wuthering Heights

“Which Canadian rapper…”

Drake

“Which French mime artist…”

Marcel Marceau

“Which street artist…”

Banksy

There must be a name for that kind of question, where the example given is one of a kind so you know the answer before the rest of the question is read out. What is it?

Edit: seeing as no one has a better idea, I’m going to start calling these “Banksys”
