Re: [語文] 請各位大大幫忙看一下兩題CR，謝謝~
※ 引述《kimoqueen (AT苦海何時能解脫~ @_@)》之銘言：
: The population of peregrine falcons declined rapidly during
: the 1950’s and 1960’s and reached an all-time low in the early 1970’s.
: The decline was attributed by scientists to the widespread use of the
: pesticide DDT in rural areas.
: Which of the following, if true, gives the strongest support
: to the scientists claim?
: (A) DDT was not generally in use in areas devoted to heavy industry.
: (B) In the time since the use of DDT was banned in 1972,
: the population of peregrine falcons has been steadily increasing.
: (C) Peregrine falcons, like other birds of prey, abandon eggs that
: fallen out of the nest, even if the eggs remain intact.
: (D) Starling, house sparrows, and blue jays-birds the peregrine
: falcon prey on—were not adversely affected by DDT in their habitats.
: (E) Other birds of prey, such as the osprey, the bald cage, and
: the brown pclican, are found in the same area as is the peregrine falcon.
: 答案是A 但我選B
這題重點是要支持 科學家的claim：DDT是大量使用在 rural areas
(A)選項 把not去掉，即DDT是用在重工業的地方，反駁郊區，加上not剛好是支持
不過這個選項也有點缺陷，因為他也沒提到 rural areas是否就沒有重工業....
(B)即使population穩定成長，還是不足以支持DDT是用在郊區

: In the 1960’s long-term studies of primate behavior often used as
: subjects tamaris, small monkeys that were thought ideal because they
: require only small cages, breed frequently, and grow quickly.
: Field studies were not used because they were costly and difficult.
: Tamarinds were kept caged in male-female pairs, because otherwise,
: serious fights erupted between unrelated females. On the basis
: of the fact that breeding occurred, tamarinds were viewed as monogamous.
: The view taken by the researchers concerning the monogamy of tamarinds
: deepened on a questionable assumption.
: Which of the following could have served as that assumption?
: (A) The suppression of fighting between related females serves to
: protect their common genetic inheritance.
: (B) Adult male tamarinds contribute to the care of tamarind infants.
: (C) The social system of tamarinds requires monogamous pairing.
: (D) Male tamarind monkeys do not display aggressive behavior in the wild.
: (E) The way the tamarinds were kept in cages did not affect their
: mating behavior.
: 答案是E，但我選C
: 請各位大大幫我分析一下，謝謝~ 感恩~ ^_^
考假設，優先考慮有not的選項
剩D,E
(E) 在cages中會影響牠們的 mating behavior,所以在cage外就不一定是一夫一妻制了
