[問題] 想請問一題吳中東閱讀

[mile ()]

大家好 目前在做一題閱讀時不太瞭解
想問問大家是如何解題的

原文：
As of the late 1980’s. neither theorists nor
large- scale computer climate models could accurately
predict whether cloud systems would help or hurt a warming globe.
Some studies suggested that a four percent increase m
stratocumulus clouds over the ocean could compensate for
a doubling in atmospheric carbon dioxide, preventing a potentially disastrous
planetwide temperature increase. On the other hand,
an increase in cirrus clouds could increase global warming.

That clouds represented the weakest element
in climate models was illustrated by a study of
fourteen such models. Comparing climate forecasts for a world with double
the current amount of carbon dioxide, researchers found
that the models agreed quite well if clouds were riot included. But when
clouds were incorporated, a wide range of forecasts was produced. With such
discrepancies plaguing the models, scientists could not easily
predict how quickly the world’s climate would change, nor could they tell
which regions would face dustier droughts or deadlier monsoons.

題目：
It can be inferred that the primary purpose of the models included in the stud
y discussed in the second paragraph of the passage was to


A predict future changes in the world’s climate
B predict the effects of cloud systems on the world’s climate
C find a way to prevent a disastrous planet wide temperature increase
D assess the percentage of the Earth’s surface covered by cloud systems
E estimate by how much the amount of carbon dioxide in the Earth’s atmosphere
will increase

吳中東的答案： （B)
但我選了 （A), 我在網路上搜尋也找到一個網站在這題的答案也是（A)
我是根據第二段倒數第二和三行選的
不知道我有沒有誤解文章內容或題目？
想請大家幫忙一下
感謝！

推 kaifrankwind:第二段的第一句就是那份研究的主旨了 (A)是從那研究
→ kaifrankwind:延伸出來的結論
