Examination, trial (4)
I believe the answer is:
test
I believe this is a double definition.
'examination' is the first definition.
(I know that examination can be written as test)
'trial' is the second definition.
(I know that trial can be written as test)
(Other definitions for test that I've seen before include "Experiment" , "criterion" , "Analyse" , "Trial - big match" , "Ward off" .)
