State answer solved in a lab (7)
I believe the answer is:
albania
'state' is the definition.
(I know that Albania is or was a European country)
'answer solved in a lab' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'solved' indicates an anagram (the anagram must be solved).
'in'+'a'+'lab'='inalab'
'inalab' is an anagram of 'lbania'.
'a'+'lbania'='ALBANIA'
(Other definitions for albania that I've seen before include "State" , "Balkan country" , "Country in the Balkans" , "One country" , "Country W of Macedonia" .)
