44. Although the prevailing supposition has been that it is too hot for microorganisms to survive deep below the Earth's surface, some scientists argue that there are living communities of microorganisms there that have been cut off from surface life for millions of years. These scientists base their argument on the discovery of living microorganisms in samples of material that were taken from holes drilled as deep as 1.74 miles. The scientists' argument depends on which of the following assumptions? (B)No holes have been drilled into the Earth's surface to a distance deeper than 1.74 miles. (C)The microorganisms did not come from surface soil that came into contact with the drilling equipment. 正確答案是（C）想請問一下(B)把NO拿掉變成有發現比1.74更深的洞不是反駁原文說因為深層太熱所以沒辦法存活嗎？那為什麼不能當假設阿 50. To produce seeds, plants must first produce flowers. Two kinds of tarragon plants, Russian tarragon and French tarragon, look very similar except that Russian tarragon produces flowers and French tarragon does not. The leaves of Russian tarragon, however, lack the distinctive flavor that makes French tarragon a desirable culinary herb. If the information presented is true, which of the following can most reliably be concluded on the basis of it? (C)Plants that grow from seeds sold in a packet labeled "tarragon" are not French tarragon. (E)Garden plants that have flavorful leaves generally do not produce flowers. 為什麼(E)不對呀？ R有花=>不香 F沒有花=>不香不是滿合理的推測嗎....=___= 另外我有點不懂來欣謝老師的他因複因欸^^" 像51. New regulations in Mullentown require manufacturers there to develop five-year pollution-reduction plans. The regulations require that each manufacturer develop a detailed plan for reducing its released pollutants by at least 50 percent. Clearly, the regulations will not result in significant ^^^^^^^^ pollution reduction, however, since the regulations do not force manufacturers to implement their plans. Which of the following, if true, most weakens the argument? 這題我原本想說是will 所以代表結果為發生=>推翻果用複因但是解析是說另有他因可造成此結果讓我有點搞混他因跟複因的使用時機跟方法了請教各位牛人幫忙指點迷津謝謝！！>____<" -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.134.120.215
