Answer:
China has a comparative advantage over the US in the production of television mainly for two reasons.
The first reason is that in China, labor costs are much lower, which means that the average wage for any worker is much lower than in the United States. This attracts television manufacturers because they can reduce labor costs, meaning that they can also lower the price of the goods.
The second reason is China's sheer size. While the U.S. is a very large country, China is even larger (population-wise). This makes it easier for firms to engage in economies of scale, which leads to the reduction of overal costs.
