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

'examination' is the definition.
('scrutiny' can be a synonym of 'examination')

(Other definitions for scrutiny that I've seen before include "From close inspection" , "Close, careful examination" , "Close survey" , "City runs (anag.)" , "Close investigation" .)
