Which of the following is an entailment of the utterance "Annie broke the window"?
Annie was careless.
Annie was disruptive.
Annie did something to the window.
It is Annie who broke the window.
考查语句之间的蕴涵关系。A is an entailment of B意为“如果B，则A”，即B为真则A为真。题干中”Annie打破了窗户”为真，则“Annie对窗户做了什么”也为真，其他选项都不成立，故选C。
