stand up

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

'bear examination' is the definition.
'stand up' can be an answer for 'bear' (thesaurus). I'm not certain of the 'examination' bit.

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for stand up that I've seen before include "sort of routine" , "one has to sit? Not at all" , "Performing solo" , "To wash" , "Remain valid" .)

I've seen this clue in the Evening Standard.
