A traveler came out of the airport.There were a lot of taxies.He asked every taxi-driver his name.Then he took the third one.It cost $5 from the airport to the hotel.“How much does it cost for the whole day?” he asked,“100 dollars.” said the taxi-driver.This was very dear,but the man said it was OK.
The taxi-driver took the man everywhere.He showed him all the parks and museums in the city.In the evening they went back to the hotel.The traveler gave the taxi-driver 100 dollars and said,“What about tomorrow?” The taxi-driver looked at the man and said,“Tomorrow?It’s another 100 dollars,” But the man said,“That’s OK!See you tomorrow.” The taxi-driver was very pleased.
The next day the taxi-driver took the traveler everywhere again.They visited all the parks and museum again.And in the evening they went back to the hotel.The man gave the taxi-driver 100 dollars again and said,“I’m going home tomorrow.” The taxi-driver was sorry because he liked the traveler and,above all,100 dollars a day was a lot of money.“So you’re going home.Where do you come from?” he asked,“I’m from New York.” “New York?” said the taxi-driver,“I have a sister in New York.Her name is Susanna.Do you know her?” “Of course I know her.She gave $200 for you!”

这篇文章谁能帮我翻译一下（不太明白）

一个游客从机场出来,看到很多出租车.他一个个地询问司机的名字,然后上了第三辆车.从机场到酒店是5美金.他问司机,“包车一天要多少钱?”司机说,“100美金.”这个价钱很贵,但是游客接受了.
司机带着游客到处逛,去了所有的公园和博物馆.晚上他送游客回酒店,游客给了司机100美金,问道,“明天呢?”司机看了看游客,道,“明天?还是100美金.”游客说,“好的.明天见.”司机非常开心.
第二天司机又带着游客到处逛,又去了所有的公园和博物馆.晚上他送游客回酒店,游客又给了司机100美金,说,“明天我就回家了.”司机挺伤感的,因为他喜欢这个客人,当然,也因为100美金一天不是小数目.“嗯,你要回去了.你是从哪儿来的啊?”“纽约.”“纽约?”司机惊奇地说,“我有个姐姐（妹妹）在纽约,她叫Susanna.你认识她吗?”“我当然认识她.就是她让我给你200美金的!”

问题是：这个游客为什么乘坐这辆出租车?
答案：C- 他不想要自己掏腰包付钱

这个狡猾的游客把司机姐妹叫他给司机的200美金当做车费付了……自己一分钱没出就弄了个包车两天……他出机场时候问的名字肯定是想要问道Susanna兄弟是哪一个……
