4. Which of the following most logically completes the
argument?
Alivia‘s government has approved funds for an electricity-generation project based on the construction of a pipeline that will carry water from Lake Cylus, in the mountains, to the much smaller Lake Tifele, in a nearby valley. The amount of electricity generated will be insufficient by itself to justify the project‘s cost, even if the price of imported oil-Alivia‘s primary source of electricity-increases sharply. Nonetheless, the pipeline project is worth its cost, because ——

(A) the price of oil, once subject to frequent sharp increases, has fallen significantly and is now fairly stable
(B) the project could restore Lake Tifele, which is currently at risk of drying up and thus of being lost as a source of recreation income for Alivia
(C) the government of Alivia is currently on excellent terms with the governments of most of the countries from which it purchases oil
(D) it would cost less to generate electricity by moving water from Lake Cylus to lake Tifele than to do so by moving water from Lake Cylus to another valley lake
(E) Alivian officials do not expect that the amount of electricity used in Alivia will increase substantially within the next ten years

答案是B是没问题的，但D选项好像也挺有道理的？

……总结一下文章的意思，就是发电项目需要把水从湖C输送到湖T，然而这个项目的成本仍然高于单靠发电所带来的收益。尽管如此，政府还是批准了这个项目，因为……

B对因为，如果不建这个项目，很可能会亏更多钱（湖T带来的旅游收入没了）
D……把水从湖C运到湖T花的比运到其他湖少……so what，依然入不敷出啊，也不能带来额外收益或者减少损失。
