Why did monks and nuns promise to live their entire lives within their religious communities?

Options:
They needed to live alone to practice Christianity freely
They made a cow to devote their entire lives to god
They could better provide services to others by living in a religious community
They could no longer own property once they joined the church

The correct option is: They could better provide services to others by living in a religious community.

Monks and nuns choose to live their entire lives within their religious communities in order to dedicate themselves fully to their faith and to serve others. By living in a religious community, they can devote their time and energy to praying, studying religious texts, and performing acts of service, such as providing education, healthcare, and assistance to those in need. Living within the religious community allows them to live a life of simplicity, detachment from material possessions, and focus on spiritual growth.
