Educator: Traditional classroom education is ineffective because education in such an environment is not truly a social process and only social processes can develop students' insights. In the traditional classroom, the teacher acts from outside the group and interaction between teachers and students is rigid and artificial. The educator's conclusion follows logically if which one of the following is assumed? ['The teacher does not act from outside the group in a nontraditional classroom.', 'All social processes involve interaction that is neither rigid nor artificial.', 'Education is not effective unless it leads to the development of insight.', 'Development of insight takes place only if genuine education also occurs.']
