1.有一座吊橋，有船要通過的時候會升起來讓船過去，因此會影響上面的車子的交通。 為了改善交通。政府計畫建一座新的更高的吊橋。 問何者否定政府的計畫，有以下兩個答案都有人選： A) 大多數船的寬度大於橋墩之間的寬度 B) 換了更高的橋，更高的船也就往這個港口跑了 請問哪個才對? 2.Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they hunter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species to recover. Which of the following, if true, most seriously undermines the argument? 答案是 B. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. 我不懂為什麼? --
