Select tool (4)
I believe the answer is:
pick
I believe this is a double definition.
'select' is the first definition.
(picking is a kind of selecting)
'tool' is the second definition.
(pick is a kind of tool)
(Other definitions for pick that I've seen before include "Select - ground breaker" , "Play guitar" , "Choose - best" , "tool - it breaks" , "option" .)
