※ 引述《nemo31 (shidefan)》之銘言： : 17. (27669-!-item-!-188;#058&003302) : Urban air contains more sulfur dioxide than does rural air, and plants : in cities typically grow more slowly than do plants in rural areas. : In an experiment to see how much of the difference in growth is due to : sulfur dioxide, classes in an urban and a rural school grew plants in : greenhouses at their schools and filtered the greenhouse air to eliminate : sulfur dioxide. Plants in the urban greenhouse grew more slowly than : those in the rural greenhouse. : Which of the following, if true, would it be most important to take into : account in evaluating the result? 題目問的是evaluating the result 等於是說，答案要的是針對該實驗發現的狀況提出解釋如果沒有說明可能的差異原因，那就不是答案 : (A) The urban school was located in a part of the city in which levels of : sulfur dioxide in the air were usually far lower than is typical for : urban areas. 依答案內容沒辦法說明rural的greenhouse中植物長的比較快的原因 : (B) At both schools, the plants in the greenhouses grew much more quickly : than did plants planted outdoors in plots near the greenhouses. 範圍不對->題目沒提到outdoors的部分 : (C) The urban class conducting the experiment was larger than the rural : class conducting the experiment. 粗看有可能是答案，有說明可能的差異原因但是如果此選項為真那無法說明是sulfur dioxide造成，還是因為空間較大造成 (如果題目是問weaken實驗結果，則此答案最佳) : (D) Heavy vehicular traffic such as is found in cities constantly deposits : grime on greenhouse windows, reducing the amount of light that reaches the : plants inside. 可能是答案，因為有說明兩邊差異的可能原因 : (E) Because of the higher levels of sulfur dioxide in the air at the urban : school, the air filters for the urban school's greenhouse were changed more : frequently than were those at the rural school. 空氣濾清器換的比較快只代表都市空氣比較髒原題第五行有說在greenhouse內的空氣都是已經去掉sulfur dioxide了所以此選項為真也無法解釋差異原因 : 答案是D : 本來以為是AE其中之一 : 希望有人能幫忙解答,謝謝就結果來看，因為只剩D是可能選項所以選D -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.193.198.157
