推 lovekyoko:恩 又偷學到一招(筆記) 03/03 14:30
請注意這題是有結論句的weaken題，結論句在此用the reasoning，注意你要去weaken
的東西是the reasoning。
這邊的結論句因果關係如你所說的
disease ----- decline
你現在要去weaken的應該是這裡的因果關係，D選項雖然說的有道理，但請問
和the reasoning有何關係??
這就是大陸人所說的無關，注意問句用the這個字代表出題者假設你知道他所說的
reasoning所指為何。

: In the late 1980s, the population of sea otters in the North Pacific began to
: decline. There are two plausible explanations for the decline: predation,
: possibly by killer whales, or disease. Of these two, disease is the more
: likely, since a concurrent sharp decline in populations of seals and sea
: lions is believed to have been caused by disease, and diseases that infect
: these creatures are likely to be able to infect sea otters also.
: Which of the following, if true, most seriously weakens the reasoning?
: (A) Killer whales in the North Pacific usually prey on seals and sea lions
: but will, when this food source is scarce, seek out other prey.
: D) Following the decline in the population of the sea otters, there was an
: increase in the population of sea urchins, which are sea otters' main food
: source.
: 請教一下
: 答案是A 沒啥問題
: 但我想知道D錯哪
: 因為題目說有2可能原因 (1)predation (2)disease
: 題目尾巴說是因為disease 所以反駁他不是因為disease是predation 這是A的
: D是錯哪哩 urchins 增 otter減好像也沒錯阿

: Prep 1-23
: From 1978 to 1988, beverage containers accounted for a steadily decreasing
: percentage of the total weight of household garbage in the United States. The
: increasingly widespread practice of recycling aluminum and glass was
: responsible for most of this decline. However, although aluminum recycling
: was more widely practiced in this period than glass recycling, it was found
: that the weight of glass bottles in household garbage declined by a greater
: percentage than the weight of aluminum cans.
: Which of the following, if true of the United States in the period 1978 to
: 1988, most helps to account for the finding?
: (A) Glass bottles are significantly heavier than aluminum cans of comparable
: size.
: C) Manufacturers replaced many glass bottles, but few aluminum cans, with
: plastic containers.
: 答案C 我來看傷咖的解釋 重點在percentage
: A是陳述事實 但我想問一下 我覺得我考試看到A就會想選
: 有人可以對A做一下解釋嗎
: 是不是 "事實" 的答案一定不能選
: 謝謝
