Acceptable in one piece (3,5)
I believe the answer is:
all right
I believe this is a double definition.
'acceptable' is the first definition.
(I've seen this before)
'in one piece' is the second definition.
(in one piece can mean all right or safe)
(Other definitions for all right that I've seen before include "Safe - acceptable" , "100% agreement" , "Very well, everything's ok" , "Very well, as you ask - everything's fine" , "Allowable; fairly well" .)
