A rhetorical question is more of a statement. It is not a true question; it is a way of pulling a listener's attention by asking a question and then answering. The signer does not expect the listener to reply.
The attention-catching rhetorical statements are usually accompanied with the raised brows and slightly tilted head.
The rhetorical question words often occur in the middle of the sentences. The common rhetorical question signs are: why, reason, how, what, and where.
Example: last-year, ix-me finally got-into ix-there school /\how/\ my mother poss former classmate work there.
