填空题 A window cleaner was cleaning windows on the fifteenth floor of a skyscraper when he slipped and fell. He suffered only minor bruising. How was this possible when he was not wearing a safety harness and nothing slowed or interrupted his fall?

【正确答案】

【答案解析】He was inside the building.[解析] 题干中描述了一个正在擦拭摩天楼第十五层的窗户的人滑倒摔了下来，他并没戴安全帽或有其他东西可以减缓或阻止他摔倒，但他却只是轻微擦伤，可知他应该是在楼内擦窗户。
