Californian Michael Schwabe said goodbye to the gas pump two years ago．He leased an electric car．Schwabe says he gets more out of driving an electric car than just a charge.
"With the price of gasoline and with the problems with clean air,it's important we get electric vehicles out on the road."
On California roads there are about two thousand electric cars．By 2003,ten percent of all new cars may be required to have zero emissions．This is a mandate automakers say it is way ahead of its time.
Gloria Bergquist of the Alliance of Auto Manufacturers says,"The technology(for zero emissions)isn't here yet;it still needs advancement in driving range to make it more appealing to a wider consumer audience."
Auto makers blame it on the batteries．Power runs out on most cars after about 70 miles．However,some cars can now go more than 100 miles on a charge．Batteries are expensive．Carmakers say there is nothing they can do about it.
Tim Carmichael of the Clean Air Coalition says,"The automakers have not built a vehicle unless required to do so,so it's very important for the state to stay committed to this program requiting automakers to build small amounts in beginning years and then the market will take off."

Right now the California Air Resources Board requires that a percentage of new cars sold should be free of emissions．What is that percentage?

A.1%．
B.5%．
C.10%．
D.100%.

阅读作品片段，回答问题：
任凭你爱排场的学者们怎样铺张，修史时候设些什么“汉族发祥时代”“汉族发达时代”“汉族中兴时代”的好题目，好意诚然是可感的，但措辞太绕湾子了。有更其直捷了当的说法在这里——
一，想做奴隶而不得的时代；
二，暂时做稳了奴隶的时代。
这一种循环，也就是“先儒”之所谓“一治一乱”；那些作乱人物，从后日的“臣民”看来，是给“主子”清道辟路的，所以说：“为圣天子驱除云尔。”
现在入了那一时代，我也不了然。但看国学家的崇奉国粹，文学家的赞叹固有文明，道学家的热心复古，可见于现状都已不满了。然而我们究竟正向着那一条路走呢 百姓是一遇到莫名其妙的战争，稍富的迁进租界，妇孺则避入教堂里去了，因为那些地方都比较的“稳”，暂不至于想做奴隶而不得。总而言之，复古的，避难的，无智愚贤不肖，似乎都已神往于三百年前的太平盛世，就是“暂时做稳了奴隶的时代”了。
但我们也就都像古人一样，永久满足于“古已有之”的时代么 都像复古家一样，不满于现在，就神往于三百年前的太平盛世么
自然，也不满于现在的，但是，无须反顾，因为前面还有道路在。而创造这中国历史上未曾有过的第三样时代，则是现在的青年的使命!
（1）在本片段中，作者提出了哪三个时代
