Passed up again (3)
I believe the answer is:
did
'passed' is the definition.
(doing is a kind of passing)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for did that I've seen before include "Acted" , "Achieved; cheated" , "Performed an action" , "Swindled" , "Carried out an act" .)
