They may be required to be met (7)
I believe the answer is:
demands
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe there's an association between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for demands that I've seen before include "Requests forcefully" , "Asks peremptorily" , "Insists upon" , "Orders" , "Insistent requests" .)
