We learn from the last paragraph that ______.
A．Scientists have found the cause of anorexia nervosa and bulimia.
B．It is wrong to place great emphasis on thinness in women.
C．Once the mother is an anorexic, her children are certain to be anorexics.
D．Medical treatment is the most important and effective way of curing eating disorders.
参考答案
正确答案：B
解析：排除法。由最后一段的第一句“Little is known about what causes anorexia nervosa and bulimia.”可知，A项被排除；由第二句“Many people believe that western society's emphasis on thinness in women is largely to blame.”可推出为正确答案；第三句里的“genetic factors might also be involved”是一种可能，但没有被确认，从而C应被排除；第四句并没有肯定医学治疗是最有效的手段，B被排除。
