Final answer:
The group you are referring to is the Peace Corps, represented by option C), which requires a two-year commitment in the host country and learning the local language.
Step-by-step explanation:
To join the group founded in 1961 where you must commit to working for 2 years in the host country and learn the language, you would choose C) Peace Corps. The Peace Corps is a volunteer program run by the United States government. Its mission includes three goals: providing technical assistance, helping people outside the United States to understand American culture, and helping Americans to understand the cultures of other countries. The Peace Corps sends American volunteers abroad to work on developmental projects with host countries on issues ranging from health education to business development.
Amnesty International, mentioned as an option in the question, primarily focuses on human rights advocacy and does not require a two-year commitment in a host country. Hence, while Amnesty International is significant in the sphere of global governance and has had an influential role in international human rights, it is not the organization that the question is referring to.
