Questions answerable with "this is ..."

[Pau_v]

Hi! If someone would kindly help me with my simple question...

I would like to ask if there are other questions aside from "what is this ____?" that can be answerable with "this is ____."

Sure:

Is this A or B? This is A.
Is the earth flat? This is a stupid question!
Hello, who is this? This is Harry.
etc.

Thank you very much, Mister Micawber!!
I was stuck at the idea that only "what" questions could be answered with "this is".
Very helpful indeed.
And, yes. The question, is the earth flat?, is silly. Haha..
Thanks again!

However, "This is a stupid question!" is not really an answer to the question "Is the earth flat?". It is an exclamation, implying that I will not answer.
