And yet, how is it that the peasants were able to choose to expand their economic activity in response to the market opportunities?
■【A】They were able to do so because of our second consideration.■【B】They were relatively freer than they had been half a century earlier.■【C】 Over the course of the Fifth Reign (1868-1910), the ties that bound rural people to the aristocracy and local ruling elites were greatly reduced. Peasants now paid a tax on individuals instead of being required to render labor service to the government.■【D】Under these conditions, it made good sense to thousands of peasant families to in effect work full-time at what they had been able to do only part-time previously because of the requirement to work for the government: grow rice for the market place.

In either case, the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea-level boiling point of 100 centigrade.
Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. ■【A】The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. ■【B】The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.■【C】 By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80° to 180° centigrade. ■【D】Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces.More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.

第一步：仔细阅读待插入的句子，弄清含义，找出其中包含的衔接手段，预测可能存在的 语境。也就是：In either case, the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea-level boiling point of 100 centigrade.
句子中出现“either case”, either表示两者中“或者，任一”，意味着原文必提及两种“case”;
■ The water is usually occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. ■ The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.■ By far the most abundant form of geothermal energy occurs at the relative low temperature of 80 to 180℃entigrade.■
我们发现原文首句提及“The water is usually occurring groundwater that seeps down along fractures in the rock;”一种情况外，还提到了“less typically, the water is artificially introduced by being pumped down from the surface”这种情况，满足了“两种case”的猜测。
