Currently people in the United States eat, on the average, 1,431 pounds of food per year, 35 pounds more than in 1980. This increase is, at least in part, because people between the ages of 15 and 64 have accounted for an increasing share of the population.

Which of the following can be properly inferred from the passage above?

正确答案: E

3.    Currently people in the United States eat, on the average, 1,431 pounds of food per year, 35 pounds more than in 1980. This increase is, at least in part, because people between the ages of 15 and 64 have accounted for an increasing share of the population.
Which of the following can be properly inferred from the passage above?
(A) More than half of the current population of the United States is between the ages of 15 and 64.
(B) The population has risen since 1980.
(C) Children below the age of 15 require, on the average, more food than do people over the age of 64.
(D) Before 1980 children below the age of 15 outnumbered people between the ages of 15 and 64.
(E) Individuals between the ages of 15 and 64 consume, on the average, more food than do those younger or older.
答案是E
我不明白的是,现在比80年多了35KG而且文中说因为15到64的人的比例变大了,怎么会得出E的结论?消耗量的增长不是因为人口数量的增长么?怎么可以得出那个群体对事物的消耗比另外的群体大?
还是我理解错了?求助NN

Notice the position of the phrase "on the average." And notice the conclusion of the passage. The author already claimed that the increase of the average consumption of meat is caused by the increasing share of the 15-64 year
-old age group.

Then put the two things together, that age group must have consumed more meat on average than other age group.

Simple math.
