Question

what is one reason two countries may sign a treaty to create a free - trade agreement with one another?
to establish barriers to trade
to cut taxes
to collect more taxes
to limit trade opportunities for competing companies

Explanation:

Trade agreements between countries are often aimed at promoting trade. Cutting taxes (tariffs) on goods traded between them is a common goal to make trade more attractive and boost economic activity. Establishing barriers to trade goes against the purpose of a trade - agreement. Collecting more taxes is not the main reason as it would make trade more expensive. Limiting trade opportunities for competing companies is not the over - arching reason for trade agreements which are more about mutual economic benefit.

Answer:

to cut taxes
