Choice library area shadowing page (10)

I believe the answer is:

preference

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

'choice' is the definition.
(I know that preference is a type of choice)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for preference that I've seen before include "favourite" , "Bent" , "Choice (of A rather than B)" , "Liking for one thing more than another" , "Partiality" .)

I've seen this clue in the Sydney Morning Herald.
