1、涂料中的t因为供应不足将涨价，如果没有t就得用更多的涂料，所以厂家声称涂料将涨价。
问strength
思考：因果论证，考虑加强因果联系、排除他因削弱、类比加强或直接加强

A：涂料中除了t之外的原料都不会涨价。方向反。
B：生产t的工厂可以快速闲置或重启。方向反。
C：没有t的涂料价格并没有低到可以与含t涂料竞争。正确，排除他因削弱，如果不含t的涂料价格足够低，则多涂几层涂料可以达到t涂料同样的效果，就不用涨价了。
D：之前生产t的工厂因为t价格上升所以又转而重新生产t。方向反。
E：涂料商与化学产品供应商通常会锁定一年t的价格。方向反。

选C

2、M城市龙虾价格因为供应增加和经济疲软因而下降，但M城市之外的地区龙虾价格没有变化。
问explain
思考：类比论证，找出两者的不同点

A：M城市消费龙虾比别的地区更多。无法解释。
B：重视健康的人无论价格如何，都更倾向于选择家禽、鱼和瘦牛肉而不是龙虾。共同条件，没有比较。
C：疲软的经济让人们没那么吃奢侈食物比如龙虾了。共同条件，没有比较。
D：限制M城市捕捉龙虾的法律近期生效。反驳前提，龙虾供应会减少。
E：M城市的龙虾是软壳，不利于长期运输。正确，M城市之外的地区龙虾价格会增加运输成本，所以价格没有变化。

选E

The price of titanium dioxide, a key ingredient in house paint, is increasing due to limited supplies because many mining companies that once produced titanium ore have shifted production to other ores. Without titanium dioxide, paint colors are less bright and more coasts of paint must be applied to compensate.
-->Companies that produce paint have concluded that they will soon need to increase the prices on the paint they produce. 判断
Which of the following would, if true, most strongly support the companies’ conclusion?
A Prices for paint ingredients other than titanium dioxide are not likely to increase.（无关）
B Plants that make titanium dioxide from titanium ore can be idled and restarted relatively quickly.（无关）
C The production cost of paint without titanium dioxide is not low enough to make such paint economically viable to compete with paint containing titanium dioxide.
D Because of recent increases in the price of titanium ore, mining companies that shifted production to other ores are now shifting back to producing titanium ore.（反）
E Manufacturers of paint typically contract with chemical makers to lock in the price for at least a year's supply of titanium dioxide at a time.（反）


Summer is the peak season for Maine lobster in the United States. This summer in the state of Maine, the price of lobster has fallen dramatically. A solid harvest and diminished demand for diners adjusting to a weak economy have pushed down the retail price of lobster in Maine to that of sliced turkey. Despite this situation, lobster lovers outside Maine will see no change in price.
Which of the following would, if true, most help to explain the stability （供需不变）of the price of lobster outside of Maine?
A Residents of Maine have historically consumed more lobster than have residents of other areas of the United States.（无关）
B Health-conscious shoppers in all areas tend to prefer poultry, fish or lean cuts of beef to lobster regardless of its price. （无关）
C The weak economy has made people in all areas less likely to eat foods that are considered luxuries, like lobster. （反）
D Newly restrictive laws limiting the number of lobsters that may be caught in Maine have recently gone into effect.（无关）
E A large proportion of Maine’s summer lobster catch is soft-shelled and is thus too fragile to ship long distances.（供需没怎么变）
