The ratio of divorces to marriages has increased since 19Therefore, there must be a greater proportion of children living with only one natural parent than there was in 19Which of the following, if true, most strongly weakens the inference drawn above?
选项
A、The number of marriages entered into by women twentyfive to thirty-five years old has decreased since 1940.
B、When there is a divorce, children are often given the option of deciding which parent they will live with.
C、Since 1940 the average number of children in a family has remained approximately steady and has not been subject to wide fluctuations.
D、Before 1940 relatively few children whose parents had both died were adopted into single-parent families.
E、The proportion of children who must be raised by one parent because the other has died has decreased since 1940 as a result of medical advances.
答案
E
解析
本题是由一个现象“离婚率升高”,而推导出结论说“生活在单亲家庭中的儿童比例必定上升”,这个推理暗含的假设为“只有离婚导致生活在单亲家庭的儿童比例上升”,反对应反对这个假设.(E)指出“由于父母中一位去世而由另一位家长抚养的儿童比例减小了”,因此反对了暗含的假设,所以(E)正确。(A)、(B)均与“儿童比例的变化”没有关联;(C)、(D)入选必定犯递进推理的错误,所以(C)、(D)也不正确。
