[問題] OG Q24

Q24~25
If there is an oil-supply disruption resulting in higher international oil price,domestic oil price in open-market countries such as the United States will rise as well, wherther such countries import all or none of their oil.

24. If the statement above concerning oil-supply disruption 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 increase in international oil price?

(A) Maintaining the quantity of oil imported at constant yearly levels
(B) Increasing the number of oil tankers in itd fleet.
(C) Suspending diplomatic relations with major oil-producing nations.
(D) Decreasing oil consumption through conservation.
(E) Decreasing domestic production of oil.

答案為(D)

請問各位
選項D 其實是不是沒有辦法真的解決，國內油價被影響。 頂多只是減少被影響的程度而已?
還有我看不太懂OG對於選項A和E的解釋( Choices A and E describes policies that could actually increase the long-term impact of increases in international oil price)， 我知道不管有沒有進口國外的油 ，只要在一個開放的市場，油價都會被影響。但是，實在不了解為什麼要選項A會被解讀為確實會提高油價被影響程度。

真的不好意思!感覺我提的問題很阿呆，但是一直被卡住。我的感覺好像就是在這五個選項中選一個影響比較不大的方法。
先謝謝各位了。

(A) expenditure = price * quantity; if quantity = constant then increased (fluctuated) price = increased (fluctuated) expenditure
(B) if that means increase in demand then price becomes sensitive
(C) that won't help in price negotiation
(E) decrease of supply means increase of price sensitivity

(D) 減少用油 => 降低需求,因此減少油價對本身的衝擊

謝謝你，dibert.
你的意思就是以最終的角度去觀察，各個選項對於持續的油價上漲，最終是否會有影響?

恩!
我懂了! 謝謝! :)
