参考答案
正确答案:C
C)。由题干中的137,893nurses和Harvard定位到第四段第一句:ScientistsattheHarvardSchoolofPublicHealthinBoston,U.S.,trackedl37,893nursesagedfrom35t0770veratenyearperiodtoseehowmanydevelopedtype2diabetes.事实细节题。本题考查哈佛公共卫生学院的科学家所追踪的护士的情况。由定位句可知“美国波士顿哈佛公共卫生学院的科学家们对l37,893名年龄从35岁到77岁的护士跟踪研究了十年,观察其中有多少人患2型糖尿病”,故C)为答案。第一段最后一句指出“该项研究的对象为女性”,故排除A)“她们大多数是女性”;B)“在十多年里,她们的饮食习惯受到了严格的监控”与原文不符,故排除;该段第三句指出“在考虑了身体脂肪和体重的这类情况后……”,由此可知,所跟踪护士的身体脂肪和体重并不一样,故排除D)。
