Final answer:
A country for which imports and exports comprise a large fraction of the GDP is more likely to adopt a flexible exchange rate.
Step-by-step explanation:
A country for which imports and exports comprise a large fraction of the GDP is more likely to adopt a flexible exchange rate. When imports and exports make up a significant portion of a country's GDP, the value of its currency becomes sensitive to changes in international trade. A flexible exchange rate allows the currency to adjust based on supply and demand factors, which helps maintain competitiveness in the global market.
On the other hand, a fixed (hard peg) exchange rate is less likely to be adopted by a country heavily dependent on imports and exports, as it can lead to imbalances and disruptions in international trade.
