题目：
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.
选项:
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.
答案:
C
提问：
我解题思路-新的环境改变了植物高度；目前脑子里有的方法-1）看完题干自己可以拟出一个非常好的assumption（常识内的）-看完题干我想不出来，待定；2）排除他因-如果选项排除了XXX导致了高度变化（XXX是除了新环境因素以外所有其他因素）；也可以算assumption，C选项不错；3）另外就是取非，选项特别绕的时候我会选择取非；4）角度问题-选项的角度必须和结论的角度一样，即都是从政府/科学家等，这道题用不上；看了选项排除ABE；C我看了就是排除他因，参照物的环境没有变，则岛屿上的植物高度变化完全由岛屿环境决定，D选项我看到了height，soil，（我觉得脑补soil属于环境因素很正常吧？）俩个关键因素都在了，也就是说了环境中缺乏了植物长高的因素，这个是一个不错的assumption; 我并没有抬杠的意思；老师说的是soil就是无关；我分析了一下CD感觉的确environment-保持原汁原味的词汇的选项更安全；但是D说出了一个植物没有长高的原因-一个explanation；是不是strengthen？老师可否clarify一下assumption和strengthen的做题思路区别…
