The search engine has now compiled what it describes as a top ten of "unanswerables" – the posers where there is no simple answer – based on more than a billion questions it has been asked in the last decade. They include everything from the taxing question "what is love" to "who is the most famous person in the world?"

本次评选的十大难题是从该网站十年来网友提出的十几亿问题中挑选出来的，这些难题无法用简单的语言回答，其中有很多非常抽象难回答的问题，比如“什么是爱情”、“谁是世界上最出名的人”等等。
