The Human Development Index (HDI) is a composite measure of:

Economic growth
Technological progress
Standard of living
Political freedom

The correct answer is: c) Standard of living.

The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher if it performs better on these indicators.

Economic growth is the increase in the amount of the goods and services produced by an economy over time. Technological progress is the development of new technologies and the application of existing technologies to new products and processes. Political freedom is the degree to which a country’s citizens are able to participate in the political process and enjoy civil liberties.

While economic growth, technological progress, and political freedom are all important factors that contribute to a country’s standard of living, the HDI is specifically designed to measure the level of human development in a country. The HDI is a more comprehensive measure of human development than any of these individual factors.
