问题     Finding enough meat was a problem for primitive(原始的) man and, keeping it for times when it was scarce(缺乏的) was just as hard. Three ways were found to keep meat from spoiling(腐烂): salting(盐), drying and freezing.
    People near salty waters salted their meat. At first they probably put dry salt on it, but this kept only the outside. Later they may have pickled (腌) their meat by putting it in salt water.
    In hot, dry places, men found that they could eat meat that had dried while it was still on the bones (骨头). They later learned to cut meat into thin pieces and put it up to dry in the hot air.
    Men in cold places found that frozen(结冰的) meat didn’t spoil. They could leave their meat outside and eat it when they are pleased to.
It seems true that_____.
选项 A、freezing was the easiest way to keep meat
B、pickling was the best way to keep meat
C、dried meat stayed fresh(新鲜) the longest
D、none of these was a good way to keep meat
答案A
解析 三种方式中，最简单省事的就是办法A。
