Q22:

The sense of delayed gratification, of working now for later pleasure, has helped shape the economic behavior of our society.
However, that sense is no longer nurtured as consistently in our children as it once was. For example, it used to take a bit of
patience to put together the toys that children got in cereal boxes; now the toys come from the boxes whole.  

Which of the following is an assumption of the passage above?  

A.      The toys in cereal boxes have changed partly because the economic conditions of our society have improved.

B.       The influence of promotion gimmicks on the economic behavior of our society has increased over the years.

C.      The toys that used to come in cereal boxes were put together by the same children who played with them.

D.      art of the pleasure of any toy lie in putting the toy together before playing with it.

E.       Today's children do not expect a single toy to provide pleasure for a long period of time.

请问为什么选C呢？ D错在那里呢？

谢谢！

D是无关选项。文中意思是举了一个孩子自己拼接玩具的例子来说明the sense of delayed..has no longer exist. C选项给出一个条件原来玩拼接玩具的孩子都是他们一个人拼接完成的。这个条件证明例子里的观点，孩子们确实需要花费耐心在上面，从而支持了文章的整个论点：the sense helped shape the......
取反看，如果以前玩这个玩具的孩子就不是自己拼的，那么现在孩子玩整个组装好的玩具和以前孩子别人帮助组装的玩具这两者间就没有差别了。那么这个文章逻辑就不成立了
