题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Most household appliances use electricity only when in use.  Many microwave ovens, however, have built-in clocks and so use some electricity even when they are not in use.  The clocks each consume about 45 kilowatt-hours per year.  Therefore, households whose microwave oven has no built-in clock use 45 kilowatt-hours per year less, on average, than do comparable households whose microwave oven is otherwise similar but has a built-in clock.

Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?
People who use the artificial sweetener aspartame are better off consuming sugar,since aspartame can actually contribute to weight gain rather than weight loss.For example,high levels of aspartame have been shown to trigger a craving for food by depleting the brain of a chemical that registers satiety,or the sense of being full.Furthermore,studies suggest that sugars,if consumed after at least 45 minutes of continuous exercise,actually enhance the body's ability to burn fat.Consequently ,those who drink aspartame-sweetened juices after exercise will also lose this calorie-burning benefit.Thus it appears that people consuming aspartame tather than sugar are unlikely to achieve their dietary goals. 老师，我特纠结结论是第一句还是最后一句？还有aspartame会使大脑有饱了的感觉和后面有什么联系？看了好几遍，越看越乱唉！ 思路： 1、aspartame并不一定是high levels的. 2、sugar可能也会和aspartame一样使大脑产生饱了的感觉. 3、并不确定运动时间是否是45min，也可能不足45min. 4、aspartame-sweetened juice可能还有其他成分中有糖，并不一定会 lose calorie-burning benefit. 5、就算没有calorie-burning benefit，运动完后喝的aspartame- sweetened juice也可能没有可以增肥的成分.

Researchers took a group of teenagers who had never smoked and for one year tracked whether they took up smoking and how their mental health changed.  Those who began smoking within a month of the study's start were four times as likely to be depressed at the study's end than those who did not begin smoking.  Since nicotine in cigarettes changes brain chemistry, perhaps thereby affecting mood, it is likely that smoking contributes to depression in teenagers.

Editorial:
 
In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker's income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.
 
Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?
