单选题 Years ago, consumers in Finland began paying an energy tax in the form of two Finland pennies for each unit of energy consumed that came from nonrenewable sources. Following the introduction of this energy tax, there was a steady reduction in the total yearly consumption of energy from nonrenewable sources.
If the statements in the passage are true, then which of the following must on the basis of them be true?

A、 There was a steady decline in the yearly revenues generated by the energy tax in Finland.
B、 There was a steady decline in the total amount of energy consumed each year in Finland.
C、 There was a steady increase in the use of renewable energy sources in Finland.
D、 The revenues generated by the energy tax were used to promote the use of energy from renewable sources.
E、 (E) The use of renewable energy sources in Finland greatly increased relative to the use of nonrenewable energy sources.

【正确答案】 A

【答案解析】[解析] 本题属于数学相关类的归纳题型。很明显，对每单位再生资源的能源的消费征收税额既定，而引入此税后，每年对此能源的消费减少，所以稍运用数学思维，即知(A)正确，即由该能源所征的税收不断减少；(B)探讨的是每年消费的能源总量，范围过大；(C)、(D)、(E)中均有新概念“renewable energy”，归纳中必然不对。
