根据国外论坛的解释——Option B says: that restriction of 5% has never been reached, so dropping that restriction would have no effect on the Expected Outcome and hence plan will fail.
看了那么多解释,还是7楼的最靠谱~~ 但它也增加了太长的迷惑选下你嘅选项了吧~~搞得我以为重点是后面。 狩猎期的提前结束是因为已经达到了5%的数量,那么就证明了人类会大量捕杀geese,如果这样的话,drop the restriction后人类定会更多的捕杀geese,那样就不会再threaten the bird 啦~~ 这样的2头选项叫人如何选吖~~~!
