Question

what role does competition play in international trade?
it results in higher prices.
it discourages imports.
it drives down prices for consumers.
it does away with the need for investment.

Explanation:

In international trade, when there is competition among producers and suppliers, they strive to attract consumers. To do so, they often lower prices. Higher prices are not a result of competition. Competition doesn't discourage imports as it can involve both domestic and foreign - sourced goods vying for market share. And competition doesn't eliminate the need for investment as firms need to invest to stay competitive.

Answer:

It drives down prices for consumers.
