阅读下面的语段，回答问题。
         ①一个细菌经过20分钟左右就可一分为二；一根葡萄枝切成十段就可能变成十株葡萄；仙人掌切成几块，每块落地就生根；一株草莓依靠它沿地“爬走”的匍匐茎，一年内就能长出数百株草莓苗……凡此种种，都是生物靠自身的一分为二或自身的一小部分的扩大来繁衍后代，这就是无性繁殖。无性繁殖的英文名称叫“Clone”，音译为“克隆”。实际上，英文的“Clone”来源于希腊文“Klone”，原意是用“嫩枝”或“插条”繁殖。时至今日，“克隆”的含义已不仅仅是“无性繁殖”，凡来自一个祖先，无性繁殖出的一群个体，也叫“克隆”。这种来自一个祖先的无性繁殖的后代群体也叫“无性繁殖系”，简称无性系。
        ②自然界的许多动物，在正常情况下都是依靠父方产生的雄性细胞（精子）与母方产生的雌性细胞（卵子）融合（受精）成受精卵（合子），再由受精卵经过一系列细胞分裂长成胚胎，最终形成新的个体。这种依靠父母双方提供性细胞、并经两性细胞融合产生后代的繁殖方法就叫有性繁殖。但是，如果我们用外科手术将一个胚胎分割成两块、四块、八块……最后通过特殊的方法使一个胚胎长成两个、四个、八个……生物体，这些生物体就是克隆个体。而这两个、四个、八个……个体就叫做无性繁殖系（也叫克隆）。
       ③可以这样说，关于克隆的设想，我国明代的大作家吴承恩已有精彩的描述——孙悟空经常在紧要关头拔一把猴毛变出一大群猴子，猴毛变猴就是克隆猴。

根据短文内容，完成下列问题。

       Almost every kid in this country has ever eaten Hershey chocolate. But do you know that the Hershey chocolate factory is more than one hundred years old? And do you know that the father of Hershey Chocolate, Milton Hershey, had many failures in business before he started his famous company?

       Milton Hershey grew up in Pennsylvania. Before he became interested in making chocolate, he worked as a printer for a small newspaper at first, and then decided that printing was not the right job for him.

       Then he worked at a candy factory in Lancaster. After working a few years there, he decided to open his own little candy business near Philadelphia. His first business failed because it was not making money. After that, he went to Denver to learn how to make caramels(焦糖). He took his new skills back to New York and worked selling candies on the street. But his second business also failed.

       Finally, Milton Hershey moved back to Pennsylvania where he grew up. He then experimented with all sorts of different candies and chocolate. By 1893 he was selling a million dollars worth of caramel candy each year. Since his chocolate-flavored(巧克力味的) caramels were the best selling, he decided to make chocolate himself.

       By experimenting, Milton Hershey discovered how to make delicious chocolate. The area where he lived had a large and easy suppl y of milk and sugar, which helped him succeed in his c hocolate business. In 1903, Milton Hershey built a huge chocolate factory and a town to go with it.

       Today, the town of Hershey is still the home if the factory that Milton Hershey built. And if you ever visit, you can smell delicious chocolate smells just but driving through the town.

       The factory is not so hard to find, Just travel down Cocoa Avenue until you get to East Chocolate Avenue. Turn right at the traffic lights and just follow your nose.
