[問題] Gwd 3-38

[lovekyoko (匹茲堡的天空)]

GWD3-Q38:
Kate:  The recent decline in numbers of the Tennessee warbler, a North
American songbird that migrates each fall to coffee plantations in South
America, is due to the elimination of the dense tree cover that formerly was
a feature of most South American coffee plantations.
Scott:  The population of the spruce budworm, the warbler’s favorite prey in
North America, has been dropping.  This is a more likely explanation of the
warbler’s decline.
Which of the following, if true, most seriously calls Scott’s hypothesis
into question?
A.The numbers of the Baltimore oriole, a songbird that dose not eat budworms
but is as dependent on South American coffee plantations as is the Tennessee
warbler, are declining.

B.The spruce-budworm population has dropped because of a disease that can
infect budworms but not Tennessee warblers.

C.The drop in the population of the spruce budworm is expected to be only
temporary.

D.Many Tennessee warbler have begun migrating in the fall to places other
than traditional coffee plantations.

E.Although many North American songbirds have declined in numbers, no other
species has experienced as great a decline as has the Tennessee warbler.


答案a

Scott說 因為 budworms 下滑 所以吃他的warbler也下滑  要反駁這說法

請問A哪裡有反駁

我上CD看是說 這題是 異因同果的反駁

因為A說 oriole也下滑(同樣的果) 但是他不吃budworms(異因)

請問  這樣哪裡有反駁阿???  感覺不出來

所以反駁的題型只要碰到選項有

異因同果 同因異果  都算反駁嗎???

日情蒐點名--郭勇志︰會怕就好
〔記者羅惠齡／台中報導〕今年日本出版的新球季日本職棒球員名鑑，在分析亞錦賽議
題中，將郭勇志列為台灣隊注目投手之一，郭勇志不好意思地表示，大概是去年成績不錯
，被注意到了。將郭勇志列入要特別注意的球員，是因為他去年獲得聯盟救援王，控球
、直球速度及壓制能力都不錯，有機會獲國家隊青睞。看到自己被日本人注意到，郭勇
志意外之餘也表示︰「會怕就好。」

→ Vierro:兩者都as dependent on coffee plantation 固另一種不吃蟲
→ Vierro:的鳥也下降 代表下降與吃蟲無關~(言下之意 與
→ Vierro:tree cover有關)
→ Vierro:要找一個共同的因解釋兩種鳥的下降 固反駁吃蟲@@~
