某集团公司为扩展业务，计划采购一批运输车辆，现有两种方案可供选择。
第1方案是采购10辆进口车辆，每辆车辆的离岸价格是3万美元，海上运费和运输保险费为1500美元/辆，银行财务费率为5‰，外贸手续费率为1.5%，进口关税税率为22%，增值税的税率为17%，美元的银行牌价为每美元8.3元人民币，车辆的国内运杂费率为6000元/辆。假定其他税费暂不考虑。第2方案是采购14辆国产车辆才能达到同等效果，价格为20万元/辆，需要交纳购置税等费用2万元/辆。
每车的车辆操作人员的平均工资为30000元/年，设备的使用寿命均为8年，8年内进口车辆和国产车辆均可行驶80万公里，8年后车辆报废，没有残值。
在运营期间，每辆进口车的燃油成本、日常维护成本和大修成本合计为0.7元/km，每辆国产车的燃油成本、日常维护成本和大修成本合计为0.6元/km。
上述财务数据中，除人工费、外汇汇率外，不存在价格扭曲现象，进口车辆的劳动力影子价格转换系数按1.2计算，国产车辆按1.0计算，影子汇率转换系数为1.08，社会折现率为10%。复利系数见表4。

问题：

对上述两方案进行比选，推荐一个方案，并说明理由。

阅读材料，回答下列问题。

医疗改革是世界性难题。2010年，美国奥巴马总统的医疗改革法案在国会获得通过。但由于公共卫生属于各州的“保留权”，有过半的州对医改法案发起挑战，认为奥巴马的医改法案是对州主权史无前例的侵犯。2012年6月，美最高法院裁决奥巴马医改法案要求各州扩大医保补助范围的规定侵犯了各州权力。奥巴马表示，如果各州能够实现原定医改目标，各州可以在2014年起单独制定医改法案，并放弃执行联邦政府的计划。

2008年底，我国成立国务院深化医药卫生体制改革领导小组，统筹组织实施医药卫生体制改革。各地从本地实际出发，切实抓好组织落实、创新试点工作。到2013年底，我国已构建起世界上最大的全民基本医保网，为世界难题的解决提供了“中国方案”。这离不开我国政府强大的组织优势。

One of the most famous buildings in the United States is Carnegie hall ,the home of classical and popular music concerts in New York. Carnegie Hall is known not just for its beauty and history, but also for its amazing sound .It has been said that the hall itself is an instrument. It takes the music and makes it larger than life.

Carnegie Hall is named after Andrew Carnegie, who paid for its construction .Construction of Carnegie Hall began in 1980 and the official opening night was on May 5,1891.

The hall was owned by the Carnegie family until 1924 when it was sold to Robert E. Simon。The building became very old and in 1960,the new owner made plans to destroy it and build an office block. Isaac Stern led a group of people who fought to save Carnegie Hall and finally ,the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.

In 1986,people realised that Carnegie Hall had never kept proper records of its history.

Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall 's concert history.

Carnegie Hall is actually made up of several different halls ,but the Main Hall, now called the Isaac Stern Auditorium, is the most famous. The hall itself can hold an audience of 2804 in five levels of seating .Visitors to the top level have to climb up 105 steps to get there!

Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there.
