请问E选项为何不行??

Q40:

From 1973 to 1976, total United States consumption of cigarettes increased 3.4 percent,

and total sales of chewing tobacco rose 18.0 percent. During the same period, total

United States population increased 5.0 percent.

If the statements above are true, which of the following conclusions can be properly drawn?

A. United States manufacturers of tobacco products had higher profits in 1976 than in 1973.

B. Per capita consumption of cigarettes in the United States was lower in 1976 than in 1973.

C. The proportion of nonsmokers in the United States population dropped slightly between 1973 and 1976.

D. United States manufacturers of tobacco products realize a lower profit on cigarettes than on chewing tobacco.

E. A large percentage of United States smokers switched from cigarettes to chewing tobacco between 1973 and 1976.

我的思路：在这段期间内，抽cigarette的人增加了3.4%(比平均增加人口少)chewing tobacco的人增加18%(比平均增加人口多)所以除了增加的人口里都chewing tobacco外，抽cigarette的人应该会有一些转移到chewing tobacco，才会造成 tobacco的人口增加这么多，不是吗??
