What is the main purpose of the World Bank?

The main purpose of the World Bank is to assist developing countries in reducing poverty. This organization provides financial and technical assistance to support projects that improve economic prospects and promote sustainable development. The World Bank's focus is on projects that can improve education, health, infrastructure, and agriculture, among other areas, all aimed at improving living standards and reducing inequality. By investing in these development goals, the World Bank plays a crucial role in helping countries achieve long-term economic growth and stability, which is essential for lifting people out of poverty.

The other options do not capture the World Bank's primary mission. The organization does not control global monetary policy, nor does it finance military projects, as its focus is on development and poverty reduction rather than military or technology investments.
