Educator: Conclusion Traditional classroom education is ineffective because Support education in such an environment is not truly a social process and Support only social processes can develop students' insights. ██ ███ ███████████ ██████████ ███ ███████ ████ ████ ███████ ███ █████ ███ ███████████ ███████ ████████ ███ ████████ ██ █████ ███ ███████████
Summary
Traditional education is ineffective, because it is not a social process, cannot develop student insight, and teacher-student interaction is rigid and artificial. 
Missing Connection
The educator’s conclusion is about effectiveness, but the argument has not defined what qualifies for effectiveness. To validly draw the conclusion, we need to know that one of the qualities of traditional education would disqualify it from being effective.

The educator's conclusion follows logically ██ █████ ███ ██ ███ █████████ ██ ████████
a
Development of insight █████ █████ ████ ██ ███████ █████████ ████ ███████
We don’t know anything about what genuine education is. (A) also does not bridge the idea of effectiveness, which is what we need.
b
Classroom education is █████████ ██ ███ ███████████ ███████ ████████ ███ ████████ ██ ███████ █████ ███ ███████████
We cannot use this to support the conclusion that traditional education as ineffective. In the context of traditional education, we would only be able to negate the sufficient condition using this conditional, and that doesn’t lead to any valid kind of inference.
c
All social processes ███████ ███████████ ████ ██ ███████ █████ ███ ███████████
(C) tells us that traditional education is not a social process, but we already knew this (”education in such an environment is not truly a social process”). We need something that bridges traditional education to the criteria of effectiveness, and defines how traditional education has failed that criteria.
d
Education is not █████████ ██████ ██ █████ ██ ███ ███████████ ██ ████████
This guarantees that traditional classroom education is not effective. The contrapositive of (D) is that if something does not develop insight (which is triggered by traditional classroom education), then that thing is not effective.
e
The teacher does ███ ███ ████ ███████ ███ █████ ██ █ ██████████████ ██████████
We are not trying to support a conclusion about the nontraditional classroom, we are trying to conclude that traditional classrooms are ineffective. We need something that bridges the idea of effectiveness to traditional classrooms.
