22. A long-term health study that followed a group of people who were age 35 in 1950 found that those whose weight increased by approximately half a kilogram or one pound per year after the age of 35 tended, on the whole, to live longer than those who maintained the weight they had at age 35. This finding seems at variance with other studies that have associated weight gain with a host of health problems that tend to lower life expectancy.

Which one of the following, if true, most helps to resolve the apparently conflicting findings?

(A) As people age, muscle and bone tissue tends to make up a smaller and smaller proportion of total body weight.

(B) Individuals who reduce their cholesterol levels by losing weight can thereby also reduce their risk of dying from heart attacks or strokes.

(C) Smokers, who tend to be leaner than nonsmokers, tend to have shorter life spans than nonsmokers.

(D) The normal deterioration of the human immune system with age can be slowed down by a reduction in the number of calories consumed.

(E) Diets that tend to lead to weight gain often contain not only excess fat but also unhealthful concentrations of sugar and sodium.

我认为应该选D。但是答案...

跟身体不重有什么关系吗？我认为文中所论述的焦点是为什么有人在35岁后增重长寿，而with a host of health problems 的人增重却短寿

"This finding seems at variance with other studies that have associated weight gain with a host of health problems that tend to lower life expectancy." 这句应该是引起冲突的论据吧。

是不是我这句话理解有错误

哦，好像明白了。

答案为前一个study的现象作出了解释，以削弱同第二个study的冲突，对吧

但是我始终认为这是一个跟增重有关的话题，而答案C是相对减重，有点不对劲

总算明白了，谢谢。

“other studies that have associated weight gain with a host of health problems that tend to lower life expectancy.”我对这句话的理解一开始出现了严重问题。
