问题     Most Americans have at least one credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad. And they also make many banking services available. For many of us the "cashless society" is already here.
    While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made.
    At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customers for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer-aided marketing reports can help to decide which products to emphasize now, which to develop for the future, and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
    Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
From the passage, electronic cash registers are not able to keep record of______.

选项 A、when the goods were sold
B、the exact salesmen who sold the goods
C、what goods were sold
D、when the goods were returned to the suppliers

答案D

解析 细节推理题。题目询问根据文章,电子收款机不能记录什么。本题答案可以从第二段中的“…who sold what,when,and to whom.”得知其中不包括何时退货的记录。该段末句也说明退货给供应商是商家在了解电子收款机的记录之后要做的决定,而不是收款机本身的记录。因此选项D为正确答案。
