Take a borderline view? (3,2,3,5)
I believe the answer is:
sit on the fence
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for sit on the fence that I've seen before include "Be indecisive" , "pin down criminal" , "refuse to support either side" , "Vacillate" , "Refuse to commit oneself" .)
