Argument Breakdown
Notice that this argument takes the form of a series of conditional statements expressing necessary conditions. Let's start with the first one. Teachers are effective only when they help students become independent learners:
effective → students independent
Next, we're told that "not until" teachers have the power to make decisions in their own classrooms can they enable students to make their own decisions:/p>
students make own decisions → teacher makes decisions in classroom
We're then told that student's capacity to make their own decisions is "essential" (a necessary condition) to them becoming independent learners:
students independent → students make own decisions
The conclusion links all these conditional statements together: if teachers are to be effective, they must have the power to make decisions in their own classrooms:
effective → students independent → students make own decisions → teacher makes decisions in classroom
effective → teacher makes decisions in classroom
Strategy: Must Be False
Normally, for a Must Be False question with as many conditional statements as this one, it would make more sense to go straight to the answer choices and proceed by elimination. But in this case, the question stem specifically gives us an initial condition: we're talking about teachers who have enabled their students to make their own decisions.
Notice where this condition fits into the chain of conditionals we put together at the end of our analysis above. It's third in line:
effective → students independent → students make own decisions → teacher makes decisions in classroom
Since teachers enabling students to make their own decisions is a necessary, not a sufficient, condition for teachers being effective and for students being independent, it could be true that the teachers are either effective or not effective, and the students could likewise be either independent or not independent. But enabling students to make their own decisions requires teachers to be able to make decisions in the classroom. So it can't be true that these teachers do not have the power to make decisions in the classroom.

According to the argument, each ██ ███ █████████ █████ ██ ████ ██ ████████ ███ ████ ███████ █████ ████████ ██ ████ █████ ███ █████████ ███████
a
Their students have ███ ██████ ███████████ █████████
This could be true. Remember that teachers enabling their students to make their own decisions is a necessary, not a sufficient, condition for students being independent learners. So it could be true that these students have not become independent learners. (A) isn't the answer choice we're looking for.
b
They are not █████████ █████████
This could be true. Teachers enabling students to make their own decisions is a necessary, not a sufficient, condition for teachers being effective. So (B) isn't what we're looking for.
c
They are effective █████████
This could be true. If these teachers were effective, then they would have to have enabled their students to make their own decisions in the classroom, as we know they have. So (C) doesn't have to be false, and isn't the answer choice we're looking for.
d
They have the █████ ██ ████ █████████ ██ █████ ███ ███████████
This must be true. If these teachers have enabled their students to make their own decisions in the classroom, then these teachers must have the power to make decisions in the classroom. (D) isn't what we're looking for.
e
They do not ████ ███ █████ ██ ████ █████████ ██ █████ ███ ███████████
This must be false. Again, if these teachers have enabled their students to make their own decisions in the classroom, then these teachers must have the power to make decisions in the classroom. (E) can't be true, so it's the answer choice we want.
