Question

　　Believe it or not, American's favorite snack food is the potato chips. There is a story behind how it was first made. One might somewhere a genius thought up the first potato chips, but it didn't happen that way. Picture an elephant restaurant in Saratoga Springs, New York, in 1853. The Moon Lake Restaurant's menu included Frenchfried potatoes, a popular food recipe brought back from France by Thomas Jefferson. There were thickly cut potatoes, fried until golden brown and crisp on the outside. One evening a guest in the dining hall felt that his potatoes were too thick and sent them back to the kitchen. The cook sliced some potatoes thinner than before and prepared them for the complaining guest. He was still not satisfied and sent them back again! By this time the cook was angry and decided to do exactly what the dinner guest wanted：slice the potatoes as thin as possible. When they would be so crisp that the diner wouldn't be able to use his fork to eat them. When the paper-thin browned potatoes arrived, the diner was satisfied. He was so happy with them that other guests started ordering the new potatoes. The cook's plan to stop the dinner guest from complaining did not turn out as he had planned. Soon Saratoga chips appeared on the menu and became so popular that people wanted to take some home. The restaurant started selling all over the United States. But be cause the potatoes had to be peeled（削皮）by hand, it was a timeconsuming（耗时的）chore and potato chips were often out of stock. In the 1920s a mechanical potato peeler was invented and soon there were potato chips in abundance（充足）. They gradually spread all over the world, and have remained popular ever since.

Answer 1

答案：A;D;C
解析：

(1) 从文章最后可知，削土豆的机器发明以后，土豆条的量才充足起来。 (2) 从文章可知，由于一名顾客不断抱怨土豆太厚了，厨师不得已才不断改进的，目的当然是为了平息顾客的怨气。 (3) 根据最后一、二句，可知土豆条是在20世纪20年代逐步普及受欢迎的，距今不到100年，20年代不一定就是1920年，故B项不选。
