GWD4-Q38

[cuteone]

Q38:Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers. This population’s descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland. Tufe Island is significantly drier than Tufe Peninsula was. So the current average height of Tufe’s Turfil sunflowers is undoubtedly at least partially attributable to changes in Tufe’s environmental conditions.
Which of the following is an assumption on which the argument depends?
A.There are no types of vegetation on Tufe Island that are known to benefit from dry conditions.
B.There were about as many Turfil sunflowers on Tufe Peninsula two centuries ago as there are on Tufe Island today.
C.The mainland’s environment has not changed in ways that have resulted in Turfil sunflowers on the mainland growing to be 40 centimeters taller than they did two centuries ago.
D.The soil on Tufe Island, unlike that on the mainland, lacks important nutrients that help Turfil sunflowers survive and grow tall in a dry environment.
E.The 40-centimeter height difference between the Turfil sunflowers on Tufe Island and those on the mainland is the only difference between the two populations.

我想問E錯在哪呢??

簡單的說
E如果是前提
推不出結論說是氣候影響兩地植物高矮
因為仍有可能是其他因素造成這唯一不同

不知道這樣可不可以讓你解
再討論∼∼

恩..了解了 :)

我還是不懂耶
因為C的意思不是說，大陸上的氣候沒有變，導致太陽花比以前高40 公分，
可是這樣不就違反了題目的意思了嗎？
題目不是說，島上因為乾燥才導致島上的太陽花比大陸上的太陽花還要短~~
呵呵~這樣C會是他的假設嗎？

C.The mainland’s environment has not changed in ways that have resulted in Turfil sunflowers on the mainland growing to be 40 centimeters taller than they did two centuries ago.

C的選項用意是要固定大陸上氣候這個因素,這個因素沒有固定的話就沒辦法比較
結論是說太陽花的高到去決於環境因素的改變
大陸上的環境因素給他固定後,就會有個基準來作為比較環境因素的改變到底長什麼樣子
