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！！>____<"
