问题     The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it re-stricted when it is within the legal and moral boundaries of society. The structure of American society al-lows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a com-pletely sedentary life-style without any exercise. The freedom to make such personal decisions is a funda-mental aspect of our society, although the wisdom of these decisions can be questioned. Personal choic-es relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.
    A multitude of factors, both inherited and environmental, influence the development of health-related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health-related behavior is usually one of personal choice. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Crapo draw a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life Is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.
Sound personal health choice is often difficult to make because____.
选项 A、current medical knowledge is still insufficient
B、there are many factors influencing our decisions
C、people are usually influenced by the behavior of their friends
D、few people are willing to trade the quality of life for the quantity of life
答案B
解析 题目问：为什么充分的个人健康选择很难做出?通过阅读文章可知，在人们做选择的时候，有很多因素会影响人们做出选择。以至于面对健康选择，人们也感到为难。第一段第六句“Personal choices relativeto health often cause a difficulty．”所以，答案是B。
