Question

what does the idiom in this text suggest? i walked across an empty land i knew the pathway like the back of my hand. —keane, \somewhere only we know\ the singer has never walked on the path before. the singer has walked the path many times before. the singer is in a strange and frightening place.

Explanation:

The idiom "know the pathway like the back of my hand" means to be extremely familiar with a path, which implies having walked it many times. The first option says the singer never walked the path before (contradicts the idiom), and the third option says the place is strange (also contradicts, as knowing the path well means it's not strange). So the correct interpretation is the singer has walked the path many times.

Answer:

The singer has walked the path many times before.
