问题 According to the passage, people could reduce the chance of suffering heart attack by ______. [br] Medical scientists believe that
选项 A、tests have been designed to settle the cholesterol dispute
B、drugs have been tested to reduce the amount of the substance in blood
C、low cholesterol foods or anti-cholesterol drugs or both can reduce the chance of a heart attack
D、none of the statements mentioned above is correct
答案 C
解析 此题考查学生根据事实进行推测的能力。解答此题应从文章某些内容推测所包含的观点和倾向。四个选择中，C最符合本题题意。如果选A，那就成了：医学科学家们相信，为解决胆固醇之争已经定好了试验。什么试验，试验什么内容都模糊不清。科学家们所希望的是通过两项庞大的研究计划可能会解决胆固醇之争，而不是通过试验解决争论。B为了减少血液中的物质，对药物进行了试验，这种说法欠妥，因为文章中没有提到进行过药物试验，所以不能选。D项把以上三种选择都否定了，所以也是错误的。
