Answer:
<em>The correct answer is A) The US and Western Europe are strong because they have high GDPs.</em>
Explanation:
The United States and Western Europe have among the highest GDPs in the world. GDP stands for gross domestic product, which basically is a measure of the economic activity that took place in a country.
The higher the GDP of a country, the more economic activity took place in the country and hence, generally, such countries are richer and more developed.
We can see other countries on the map, that far a lower GDP and hence, are not that powerful and do not have a strong influence on the world.
