Introduced the topic of being fostered (7,2)
I believe the answer is:
brought up
This clue could be a double definition.
'introduced the topic of' is the first definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'fostered' is the second definition.

Perhaps you can see a link between them that I can't see?
'being' is the link.
Can you help me to learn more?
(Other definitions for brought up that I've seen before include "Reared" , "Raised" .)
