题目问的是全球化的弊端还是优势？看不懂这个语法

问题如下：

Q. A consequence of one of the disadvantages of globalization is that:

选项：

A.pay differences between countries have narrowed. B.emerging market trade flows have grown more important. C.greater economic and financial cooperation has increased interdependence.

解释：

C is correct. Through the process of greater economic and financial cooperation, companies may become dependent on other countries’ resources for their supply chains. On aggregate, this can result in the nation itself becoming dependent on other nations for certain resources (such as rare earth metals, cobalt, or copper). If there is a disruption to the supply chain, including via a moment of political non-cooperation, then firms may not be able to produce the good themselves.

A is incorrect because the narrowing of pay differences between countries results from a motivation to pursue globalization, which is related to one of its advantages. It is an important way for companies to increase profitability by reducing their costs. Although wage differentials remain, they are decreasing. B is incorrect because the proportion of flows between developed economies as a share of overall trade continuing to decline as emerging market trade flows rise is a function of increased international investment. This increased investment has provided beneficial aggregate economic benefits, such as increased choice, higher quality goods, increased competition among firms, higher efficiency, and increased labor mobility.

C是正确的。通过加强经济和金融合作，企业的供应链可能会依赖其他国家的资源。总的来说，这可能会导致一个国家在某些资源(如稀土金属、钴或铜)上依赖其他国家。如果供应链中断，包括政治上的不合作，那么企业可能无法自己生产产品。

A是不正确的，因为国与国之间薪酬差异的缩小源于追求全球化的动机，这与全球化的一个优势有关。这是企业通过降低成本来提高盈利能力的重要途径。尽管工资差距仍然存在，但它们正在缩小。

B是不正确的，因为随着新兴市场贸易流量的增加，发达经济体之间的贸易流量占总贸易的比例继续下降，这是国际投资增加的一个函数。这种增加的投资提供了有益的总体经济效益，例如增加了选择，提高了产品质量，增加了企业之间的竞争，提高了效率，增加了劳动力流动性。
