参考答案

正确答案：D
解析：细节题。根据是最后一段倒数第二句：Then he turned to Linda and explained that he was not a salesman at all but a store detective．A选项和文中“But when she said she was just looking he did not seem to be listening．He did not even hear her at first．”相矛盾；She noticed that the salesman seemed to be watching another customer in the department all the time因此他并没有attend(招呼)另一名客人, 而是watch(观察), 以及后来的打电话, 因此B选项不正确；文中提到“He did not seem to understand what a detachable lining was”显然暗示他对于雨衣不太了解, 因此不选C。
