问题  The fitness movement that began in the late 1 960s and early 1 970s centered around aerobic exercise(有氧操)．Millions of individuals became engaged in a variety of aerobic activities，and literally thousands of health spas developed around the country to capitalize(获利)on this emerging interest in fitness，particularly aerobic dancing for females．A number of fitness spas existed prior to this aerobic fitness movement，even a national chain with spas in most major cities．
However，their focus was not on aerobics，but rather on weight-training programs designed to develop muscular mass，strength，and endurance in their primarily male enthusiasts．These fitness spas did not seem to benefit financially form the aerobic fitness movement to better health，since medical opinion suggested that weight-training programs offered few，if any，health benefits．In recent years，however，weight training has again become increasingly popular for males and for females．Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well．
  Historically，most physical-fitness tests have usually included measures of muscular strength and endurance，not for health—related reasons，but primarily because such fitness components have been related to performance in athletics．However，in recent years，evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well．The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans．Increased participation in such training is one of the specific physical activity and fitness objectives of Health People 2000 National Health Promotion and Disease Prevention Objectives．
People were given physical fitness tests in order to find out(          )．
选项 A、how well they could do in athletics
B、what their health condition was like
C、what kind of fitness center was suitable for them
D、whether they were fit for aerobic exercise
答案C
解析 第三段对波士顿大学医疗中心的研究做了描述，其中直接出现了“confirm”一词，验证的内容是“those who dieted without exercise regained almost all their old weight，while those who worked exercise intotheir daily routine maintained their new weight”，那些节食而不锻炼的人几乎全部反弹到原来的体重，而那些把锻炼身体列入日常项目的人则保持住了减肥后的体重。C的说法正确。
