In the past, every ten-percentage-point increase in cigarette prices in the country of
Coponia has decreased per capita sales of cigarettes by four percent. Coponia is about to
raise taxes on cigarettes by 9 cents per pack. The average price of cigarettes in Coponia
is and has been for more than a year 90 cents per pack. So the tax hike stands an
excellent chance of reducing per capita sales of cigarettes by four percent.
Which of the following is an assumption on which the argument depends?
A. Tobacco companies are unlikely to reduce their profit per pack of cigarettes to
avoid an increase in the cost per pack to consumers in Coponia.
B. Previous increases in cigarette prices in Coponia have generally been due to
increases in taxes on cigarettes.
C. Any decrease in per capita sales of cigarettes in Coponia will result mainly from
an increase in the number of people who quit smoking entirely.
D. At present, the price of a pack of cigarettes in Coponia includes taxes that amount
to less than ten percent of the total selling price.
E. The number of people in Coponia who smoke cigarettes has remained relatively
这题目说什么意思 答案是A 我有点不明白 请NN指点啊

Hope this helps.
Question stem: 10% UP in price => 4% DOWN in cigarette sales; Now tax up 9 cents on the price of 90 cents => 10% UP in price (9 cents /90 cents = 10%). So 4% down in cigarette sales is highly possible.
The logic link: the relation between price increase and sales(down).
Assumtion: In order to reach the conclusion that the sales will go down, the price will need to increase.
A. Cigarette cmopanies will not decrease the price of the cigarettes ( price of cigarettes =cost per pack to consumers) . This is the correct choice because the price is confirmed to increase, thus the sales will go down.
B. In the past, Tax up => cigarette Price up. This choice is Irrelavent because we only concern about the relationship between price and sales. Also, the past normally has nothing to do with current situations.
C. More/ increase # of people quit smoking => Down in cigarette sales. This choice is also irrelavent because it doesn't say about the relationship between price and sales.
D. current tax a pack of cigarettes < 10 % of the total selling price. This choice is irrelavent because it doesn't say about the relationship between price and sales.
E. The # of people who smoke is about the same. The choice is also irrelavent because it doesn't say about the relationship between price and sales.
