According to a study, after a week of high-altitude living, twenty men had slimmed down.The men, middle-aged residents of low-altitude areas, had been taken to a research station at 2,650 meters (8,694 feet) above sea level. They had unrestricted access to food and were forbidden vigorous exercise, yet they lost an average of 1.5 kilograms (3.3 pounds) during their one-week stay. Clearly, the lower availability of oxygen at higher altitudes, or hypobaric hypoxia, can be said to have caused the weight loss, since __________.

这道题是说在高海拔地区不限食物供应但是禁止剧烈运动的人在高海拔地区成功减重。得出高海拔地区的氧气稀薄能够导致减重，问为什么氧气稀薄能导致减重，那么就必须要在围绕氧气稀薄和减重之间建立一个关系，这个关系只有A能说明，其余选项均为无关选项。

能得到食物和能增重之间有个gap，就是这人要把得到的食物吃下去，要佐证这个结果就是说明得到再多的食物也吃不下去。

逻辑链;a week of high-altitude living （unrestricted access to food and were forbidden vigorous exercise）-->men had slimmed down-->HH caused the weight loss.A 搭桥，HH可以降低食欲，减肥；B 参加锻炼，否定前提；C 食物卡路里低，但无限量，所以不能解释，且与HH无关；D 前提说了不能锻练，无关；E 试验过后，无关
