Answer:
An increase in gross domestic product (GDP) is a sign that a country’s economy is growing.
Step-by-step explanation:
A nation's gross domestic product is a way to measure its economic activity. If the GPD decreases, the economy is declining, if the GDP increases, the economy is growing. If the GPD doesn't change, then the country's economy is stagnant.
Therefore, an increase in gross domestic product (GDP) is a sign that a country’s economy is growing.
