How to resolve a personal question (3)

I believe the answer is:

who

I'm a little stuck... Click here to teach me more about this clue!

'question' is the definition.
(who is a question word)

'how to resolve a personal' is the wordplay.
'how' can be anagrammed to 'WHO'.
But, I'm not clear how this is indicated.

Can you help me to learn more?

(Other definitions for who that I've seen before include "Doctor --, TV series" , "Unidentified" , "Which person?" , "Alien doctor" , "The - - , rock legends" .)

I've seen this clue in The Globe and Mail.
