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? 請問一下這題題目的因果是不是: environmental conditions change ----- 平均高度縮水 A. There are no types of vegetation on Tufe Island that are known to benefit from dry conditions. types of vegetation: out of scope 刪 B. There were about as many Turfil sunflowers on Tufe Peninsula two centuries ago as there are on Tufe Island today. as~as無關比較刪 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. 正解C 取非:請問這題對的原因是不是取非之後說同樣都是環境改變可是 The mainland的sunflowers比改變前還要高所以是同因生反果反駁了結論這樣說對嗎 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. 支持了結論 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 the only 刪請問這題這樣想有錯嗎謝謝. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 219.85.120.166
