do i answer?

[nathansphase]

Is this a rhetorical question?

[Vesper99]

It depends on whether you want an answer.
A rhetorical question supplies its own answer:
Would you like a good hiding?
Do you think I'm an idiot?

I believe an Oxford entry paper once asked, as one of its questions, 'Is this a question?'. Top marks went to someone who replied 'If this is an answer'.

Answer:
No, it's a demonstrative pronoun.
