题目内容
There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to five children something to do. In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks o~ their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all part of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arctic (北极的) peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent (进步). The progress from a rattle (拨浪鼓) used by a baby in 3000 B.C. to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials. The author used the example of a rattle to show that ______.

阅读以下文字，完成下列问题。 “百家讲坛”其实是一个很奇怪的坛。十年以前，丁肇中在那里讲过物理学，把物理学讲到我都能听得津津有味，很不容易。但现在这个讲坛上，讲红楼、讲清史、讲论语，大概今后还要讲与“国学”有关的一切。至于还讲不讲自然科学、现代哲学、法学、政治学、经济学等，我不知道。在我印象中，“百家讲坛”之“百家”就是赏玩传统的百家，当然中国这方面的人才很多，号为“百家讲坛”，数量是可以保证的。 国学，据说已经“返本开新”，只差大家都来践行。不过，践行什么呢？是修习个人的心性，还是以国学来格致万物？若是前者，没有什么不好。若是后者，事情就比较难办。阎崇年先生讲清史，______，史料熟，秘闻多，吸引力强，但主要是对清宫如同对待自家一般热爱的态度，这个祖宗英明，那场屠杀合理。易中天先生讲三国，权谋机变，说得津津有味，就是搞不清对权谋之术到底是赞赏还是批判。相比之下，反倒是于丹讲《论语》，固然毛病多多，总归是修身养性，更加合乎人性，但只强调指向内省而对人之外在处境无所置辞的讲法，大概不过是训育顺民。 这次钱文忠先生为商纣王翻案，称其“文武双全，功勋卓著”，以期主导舆论。前人多有怀疑商纣王并非恶到极点者，从真实认识而言，哪怕是希特勒，你也不难找出几个“功勋”来，商纣王当然也应该有一些好的地方。但到底有多好，难说，尤其在学术上“有一份证据说一份话”，就更困难。商纣王处在中国信史时代之前，怎样获得充分的证据来总括他的一生？对他的恶评有新朝代的虚报，有后时代的累加，但要翻案，还是且缓吧，重建一个对商纣王的历史结论，学术上几无可能。 对商纣王的评价，与其说是“历史评价”或者“历史学结论”，不如说是一种“舆论评价”或者“社会学结论”。想到商纣王就想到荒淫、暴虐，他已经成为一种暴虐的符号，不可置疑的事实是，商朝在纣王手中灭于周朝，一个“文武双全，功勋卓著”的帝王，怎样被一个新朝代取代，把这一点解释清楚，何其困难。 “百家讲坛”其实是娱乐业的一个景象，但貌似在布道。在这种虚妄的布道与实在的娱乐之间，人们听到一些离奇古怪的想法，并且把自己酱在莫名其妙的逻辑里。这些逻辑归总而言，就是“大丈夫只求建功立业，不必论其余；小百姓但求修好忍术，以接受治理”。寓教于乐，就这样实现了。 根据原文的内容，下列说法正确的一项是______。
For most kinds of activities, a large group of people can accomplish more and have more fun than one person alone. For example, politicians, businessmen, workers, and (31) criminals know that they must join organizations in order to be (32) .

In this way, the organization will benefit everyone in it.
