Re: [問題] 一題邏輯求教
※ 引述《minie (GoGoGo)》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?
題目是說, 科學家認為 1950~1960~1970 falcon 數量到最低點
跟農地大量使用殺蟲劑有關
: (A) DDT was not generally in use in areas devoted to heavy industry.
A DDT 並未在工業區大量使用
: (B) In the time since the use of DDT was banned in 1972, the population of
: peregrine falcons has been steadily increasing.
B 1972年以後禁用DDT falcon數量就提昇了
: (C) Peregrine falcons, like other birds of prey, abandon eggs that fallen out
: of the nest, even if the eggs remain intact.
C falcon有某些習性.....不重要
: (D) Starling, house sparrows, and blue jays-birds the peregrine falcon prey on
: —were not adversely affected by DDT in their habitats.
D falcon捕食的三種生物....blah blah
: (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.
E 提到另外一種鳥
個人認為是要找加強原論述點的部份
題目不長, 看到rural應該是關鍵字.....再看看 假設科學家所說為真
農地的使用殺蟲劑使得隼的數目減少
那非農業用地咧？科學家怎麼沒提到？
A的選項提到了非農業用地, 並且說明DDT並未在工業用地使用
相對印證了- "地點" 的影響確實是存在的
說的很繞口 但我是直接抓關鍵字代到題目中去找解答的
support的題型我也不算拿手 請版友分享心得 ... (速退)
