根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
1 From 18-25, according to I.Q. scores; but you are wiser and more experienced with increasing age.
You are smartest in your 20`s; around 30, your memory begins to go down, particularly your ability to perform mathematical computations, 2 Your vocabulary at the age of 45, for example , is three times as great as then you graduated form college. At 60, your brain possesses almost four times as much information as it did at the age of21.
3 You have the best physical sense of yourself from 15 to 24; the best professional sense form 40 to 49.
Before the age of 24, we believe that our happiest years are yet to come; over 3 0, we believe that they are behind us. A National Health survey agrees: after the age of 30, we “ become more realistic and do not view happiness as a goal in itself. If we maintain our health, achieve professional and emotional goals, happiness, we feel, will follow”.
4 Generally between 30 and 39, but the peak(顶峰) varies with different professions.
Mosart wrote a symphony(交响曲) and four sonatas by the age of 8, and Mendelssohn composed（作曲） his best known work A Midsummer Night` s Dream, at 17, but most of the great music was written by men between 33 and 39.
Though the peak in most fields comes early, most Nobel Prize winners did their top research in their late 20`s and 30`---creative people continue to produce work with high quality throughout their lives. 5 .A．When are you most creative (创造性的)？B．When are you happiest?C．When are you smartest?D．Do you know what I.Q. refers to?E. But your I.Q. for other tasks goes up.
F. Creative people usually produce a lot of works.
G. For the “well-conditioned mind”, there is no upper limit.C

(答案→)C 解析：本文叙述了人的智商在人的不同阶段的变化情况，文中说明了一是什么时间人是最聪明的，随之记忆力下降，但是人们的词汇或其他方面开始上升。二是人最幸福的时间是什么时候。三是人最具有创造力的时间是什么时候。并且文中举例说明了各个问题。【小题1】根据From 18-25, according to I.Q. scores; but you are wiser and more experienced with increasing age.叙述了人什么时间最聪明，故选C。【小题2】根据your memory begins to go down 与Your vocabulary at the age of 45, for example , is three times as great as then you graduated form college. 前者说的记忆力下降，后者说一个词汇方面的增多，所以中间缺少一个过渡句，故选E。【小题3】根据You have the best physical sense of yourself from 15 to 24; the best professional sense form 40 to 49.人们最幸福的时候，故选B。【小题4】根据Mosart wrote a symphony(交响曲) and four sonatas by the age of 8, and Mendelssohn composed（作曲） his best known work A Midsummer Night` s Dream, at 17, but most of the great music was written by men between 33 and 39.从这种例子中可以看出是人最具有创造性的时候，故选A。【小题5】根据most Nobel Prize winners did their top research in their late 20`s and 30`---creative people continue to produce work with high quality throughout their lives.故选G。

我也是这个答案
