What mean ask

Dear Student,

Your question is not clear and appears to be incomplete. Recheck your question or please be a little specific about the name of the chapter/textbook to which you are referring here so that we can provide you with some meaningful help.
However, I believe this is what your query is:
What is the meaning of ask?

To ask is to say something in order to obtain information.
For example: I asked him if he was going to London.

I hope this solves your query.
Look forward to hearing from you again!
