Day 44
1. 鱼的嗅觉（今日喜加一）
研究发现现在某地的河流里，鱼儿门都disoriented了，科学家们就假设是pesticide造成的。经过研究发现鱼儿如果受到某种化学物质的影响会失去方向感，同时又发现这些pesticides里面含有这种化学成分。因此更加证实了科学家们的假设。问evalue：确认河流里是否有这种pesticide？
【类似题目】
Capuchin monkeys in Venezuela often rub a certain type of millipede into their fur. Secretions of these millipedes have been shown to contain two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate the capuchins. The rubbing behavior is rare except during the rainy season, when mosquito populations are at their peak. Therefore, the monkeys probably rub the millipedes into their fur because doing so helps protect them against mosquitoes.
Which of the following would it be most useful to determine in order to evaluate the argument?
(A) Whether the two chemicals provide any protection for the millipedes against their own predators
(B) Whether the type of millipede used by the capuchin monkeys in Venezuela is found in other parts of the world
(C) Whether animals other than capuchins rub insects of any kind into their fur
(D) Whether the only time the millipedes are readily available to the capuchins is during the rainy season
(E)Whether secretions of any other insects accessible to the capuchins contain chemicals that repel mosquitoes
评估：找雨季和millipede之间的关联D

2. 消费和营业时间
顾客的消费和他呆在mall里的时间成正比，这个mall要新开一家cinema，顾客呆的时间不会明显增加。由于顾客在cinema里消费少，所以公司的收入会下降，【注意】之前说错了，不是问weaken，是问这个建立在哪个错误的assumption上了
assumption：顾客在cinema消费少，则在mall消费也少

3. 原题
With seventeen casinos, Moneyland operates the most casinos in a certain state. Although intent on expanding, it was outmaneuvered by Apex Casinos in negotiations to acquire the Eldorado chain. To complete its acquisition of Eldorado, Apex must sell five casinos to comply with a state law forbidding any owner to operate more than one casino per county. Since Apex will still be left operating twenty casinos in the state, it will then have the most casinos in the state.
p：m有17家；a需要卖5家，a还剩20家（含E）；
c：a数量最多
削弱：a数量不是最多，可能性，如果a卖的5家是卖给m的，那么m会有17+5=22家，比a大，选择A
Which of the following, if true, most seriously undermines the prediction?
A Apex, Eldorado, and Moneyland are the only organizations licensed to operate casinos in the state.
B The majority of Eldorado's casinos in the state will need extensive renovations if they are to continue to operate profitably.
C Some of the state's counties do not permit casinos.
D Moneyland already operates casinos in the majority of the state's counties.
E Apex will use funds it obtains from the sale of the five casinos to help fund its acquisition of the Eldorado chain.
