Answer:
the right and left ventricles
Explanation:
The right answer is exporting more goods than importing.
The trade balance is the difference, in terms of monetary value, between exports and imports of goods or goods and services (depending on the country) in an economy over a given period.
A positive trade balance means that the country exports more goods and services than it imports. A negative trade balance means that the country exports insufficiently or that its imports and thus its external dependence is important.
