※ 引述《yuanyen100 (2009 is a big year!!)》之銘言：
: Each year red-winged blackbirds stop in a certain region of Midland Province
: on their spring and fall migration. In the fall, they eat a significant
: portion of the province’s sunflower crop. This year Midland farmers sought
: permits to set out small amounts of poisoned rice during the blackbirds’
: spring stop in order to reduce the fall blackbird population. Some residents
: voiced concern that the rice could threaten certain species of rare migratory
: birds. Nevertheless, the wildlife agency approved the permits.
: Which of the following, if true, most helps to justify the wildlife agency’s
: approval of the permits, given the concern voiced by some residents?
: (A)In the region where the red-winged blackbirds stop, they are the first birds
: to be present in the spring.
: (C)Since rice is not raised in midland province, few species of birds native to
: the province normally eat rice.
: 答案是A我選C 實在看不出來A哪裡對 請大家幫幫忙 :P
題目說明每年春秋,紅赤黑鳥都會飛來M
然後秋天就會吃sunflower crop
所以農夫打算用毒米毒牠們
雖然有反對說這樣會傷到某種別的候鳥 但是還是通過了這方案
A選項說明了這黑鳥春天會第一個先現身
所以他們會先吃完毒米
其他候鳥也吃不到 所以不會傷到其他候鳥
支持了這方案的可行
C錯誤是說native bird不太會吃這米
但是題幹說明的是threaten certain species of rare migratory birds
和native birds是沒有關係的
歡迎討論
