8. If the statement above concerning oil-supply disruptions is true, which of the following policies in an open-market nation is most likely to reduce the long-term economic impact on that nation of sharp and unexpected increases in international oil prices?

(A) Maintaining the quantity of oil imported at constant yearly levels

(B) Increasing the number of oil tankers in its fleet

(C) Suspending diplomatic relations with major oil-producing nations

(D) Decreasing oil consumption through conservation（D）

(E) Decreasing domestic production of oil

不明白阿，为什么不是a呢？减少consume有什么用呢

好象是OG里的题目。

目标：减少不可预期的国际油价增长带来的冲击

对策：减少使用量（使用越少，受到影响越小）。

a中保持定量一样会受到油价冲击，因为题干中说了，open-market nation的油价会根据国际油价的变化而变化，不管是否国内产油，印象中是这样，因为你没有贴全题目：（，因此，只要import就会受到冲击。
