Inference questions 推理题
推理题的标志是在题干中出现infer/imply/suggest/indicate/most likely 这样的词汇，它和细节题属于同源题目，都需要定位并且根据文中信息来选择答案。与细节题不同的是，推理题在找到原文中定位点之后考察的是学生对于文中信息的总结概括，或者反向推理的能力。我们来看一道例题，

Extinct but, already fully marine cetaceans are known from the fossil record. How was the gap between a walking mammal and a swimming whale bridged?
