what does the idiom in this text suggest?\ni walked across an empty land\ni knew the pathway like the back of my hand.\n—keane, \somewhere only we know\\nthe singer has walked the path many times before.\nthe singer is in a strange and frightening place.\nthe singer has never walked on the path before.
Answer
Brief Explanations:
The idiom "like the back of my hand" means to know something very well, typically from having experience with it. So if the singer knows the pathway like the back of their hand, it implies they have walked it many times before. The second option is incorrect as "knowing like the back of hand" doesn't suggest a strange place, and the third option contradicts the meaning of the idiom.
Answer:
The singer has walked the path many times before.
