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. 正确答案是（C） 想请问一下(B)把NO拿掉变成有发现比1.74更深的洞 不是反驳原文 说因为深层太热所以没办法存活吗？ 那为什麽不能当假设阿 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.

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. 为什麽(E)不对呀？ R有花=>不香 F没有花=>不香 不是满合理的推测吗....=___= 另外 我有点不懂来欣谢老师的他因 复因欸^^" 像51. New regulations in Mullentown require manufacturers there to develop five-year pollution-reduction plans.
