Takes test again about society's struggles (7)
I believe the answer is:
resists
'struggles' is the definition.
'takes test again about society's' is the wordplay.
'takes test again' becomes 'resits' (as in resitting an exam).
'about' means one lot of letters goes inside another.
'society' becomes 's' (common abbreviation in names of organisations).
'resits' placed around 's' is 'RESISTS'.
(Other definitions for resists that I've seen before include "Defies" , "Struggles against" , "Opposes, puts up fight" , "Sisters (anag.)" , "Tries to stop" .)
