Question

in what way does the european union affect the rest of the world? it creates international laws for all nations to follow. it enables people to travel freely across international borders. it provides humanitarian aid to people in developing countries. it improves trade between different parts of the world.

Explanation:

The European Union (EU) is a major economic bloc. One of its significant impacts on the world is in the realm of trade. The EU has a large internal market and engages in extensive international trade agreements. While it doesn't create international laws for all nations (that's more the role of global bodies like the United Nations), and the free - travel within the EU (Schengen area) is mainly for EU citizens among EU countries (not across all international borders in a global sense), and while it may provide some aid, its most prominent global impact in the given options is on trade.

Answer:

It improves trade between different parts of the world.
