Which of the following is a sign of a strong economy?
a.) a decrease in spending power
b.) an increase in unemployment
c.) an increase in gdp (gross domestic product)

The correct answer is C. An increase in GDP is a sign of a strong economy.

Explanation:

The Gross Domestic Product (GDP) shows the value of everything produced in a country for a certain period, usually a year, and includes value added in all business, public administration and non-profit organizations. The gross domestic product can be obtained by summing the gross products of all the production companies in the country. The term GDP per capita indicates average value creation per capita in a country, and is often used as a measure of wealth levels, although the distribution between individuals is also important. The concept of economic growth is, strictly speaking, a measure that GDP per capita increases, that is, value creation increases faster than the population.
