问题如下：

Which of the following is not the advantage of free trade?

选项：

A.

The country can specialize in producing the export goods.

B.

It will relieve the problem of income inequality between country.

C.

The country will benefit from economies of scale.

解释：

B is correct.

It is argued that free trade will result in greater income inequality, because unemployment will increase in the industries that are less efficient and competitive than foreign winners.

考点：自由贸易的优缺点

解析：自由贸易可能导致更大的收入不平等，因为国内那些效率和竞争力较低的行业里的人们将大幅失业。这是国际贸易的最大弊端，所以B选项正确。

参与国际贸易的国家可以从贸易中生产自己擅长的商品，并且在扩大生产的过程中获取规模效应。所以A,C选项不入选。
