The position to ask questions? (4)
I believe the answer is:
pose
This clue might be a double definition.
'the position' is the first definition.
(I've seen this before)
'ask questions?' is the second definition.
'pose' can be an answer for 'ask' (synonyms). I'm not certain of the 'questions?' bit.
'to' is the link.
Can you help me to learn more?
(Other definitions for pose that I've seen before include "Strike an attitude as for photo" , "Attitudinise" , "Sit as model" , "front" , "Sit for a painter" .)
