Questions: Which statement describes the purpose of signing military treaties? Members share humanitarian aid during natural disasters. Members impose economic sanctions on opponents. Members seek to develop new businesses and technologies. Members agree to defend each other if attacked.

The answer is: Members agree to defend each other if attacked.

While military alliances may provide humanitarian aid during natural disasters, this is not the primary purpose of signing military treaties. Humanitarian aid is often coordinated through international organizations or specific humanitarian agreements rather than military treaties.

Economic sanctions are typically imposed through diplomatic agreements or international organizations like the United Nations, rather than military treaties. Military treaties focus on defense and security rather than economic measures.

Developing businesses and technologies is generally not the primary focus of military treaties. While military alliances may lead to technological collaboration, especially in defense technology, the main purpose of these treaties is not economic or technological development.

This is the primary purpose of military treaties. Such agreements, like NATO's Article 5, are designed to ensure collective defense, meaning that an attack on one member is considered an attack on all members, thereby providing mutual security and deterrence against potential aggressors.
