The hotel has been built on the ____ of a lake. A. boundary B. front C. edge D. border Note: I thought about “edge,” but the edge of a lake doesn’t have a drop as in “edge of a swimming pool” or “edge of a table.” I have heard the word “waterfront,” so it looks like B is the answer. Is the answer B? If not, is there a way to reason out the best answer? Here is another similar question I did wrong: http://www.italki.com/question/203423Is it correct to say whenever I see a body of water, such as an ocean, a lake, pond, swimming pool, puddle, it would be safe to use "edge." When I am talking about territories or countries, it is almost always "boundary" or "border"?
