22. (28829-!-item-!-188;#058&003748) In the late 1980s, the population of sea otters in the North Pacific began to decline. There are two plausible explanations for the decline: predation, possibly by killer whales, or disease. Of these two, disease is the more likely, since a concurrent sharp decline in populations of seals and sea lions is believed to have been caused by disease, and diseases that infect these creatures are likely to be able to infect sea otters also. Which of the following, if true, most seriously weakens the reasoning? (A) Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey. D) Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters' main food source. 请教一下 答案是A 没啥问题 但我想知道D错哪 因为题目说有2可能原因 (1)predation (2)disease 题目尾巴说是因为disease 所以反驳他不是因为disease是predation 这是A的 D是错哪哩 urchins 增 otter减好像也没错阿 -------------------------------------------------------- Prep 1-23 From 1978 to 1988, beverage containers accounted for a steadily decreasing percentage of the total weight of household garbage in the United States. The increasingly widespread practice of recycling aluminum and glass was responsible for most of this decline. However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans. Which of the following, if true of the United States in the period 1978 to 1988, most helps to account for the finding? (A) Glass bottles are significantly heavier than aluminum cans of comparable size. C) Manufacturers replaced many glass bottles, but few aluminum cans, with plastic containers. 答案C 我来看伤咖的解释 重点在percentage A是陈述事实 但我想问一下 我觉得我考试看到A就会想选 有人可以对A做一下解释吗 是不是 "事实" 的答案一定不能选 谢谢 -- 日情蒐点名--郭勇志︰会怕就好 〔记者罗惠龄／台中报导〕今年日本出版的新球季日本职棒球员名监，在分析亚锦赛议 题中，将郭勇志列为台湾队注目投手之一，郭勇志不好意思地表示，大概是去年成绩不错 ，被注意到了。将郭勇志列入要特别注意的球员，是因为他去年获得联盟救援王，控球 、直球速度及压制能力都不错，有机会获国家队青睐。看到自己被日本人注意到，郭勇 志意外之余也表示︰「会怕就好。」 --
