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.
Some people learned that they could pickle meat by_____.
选项 A、putting dry salt on it
B、soaking it in salt water
C、cooking it with salt
D、cutting it into pieces
答案B
解析 根据文中意思，B为正确选项。
