Quote:
According to the new school district policy, only teachers that have tiled floors can have food in their classrooms. All of the classrooms in the new wing of the high school have tiled floors. However, most of the school's classrooms are still carpeted. Therefore, teachers who like to eat their lunches in their classrooms should be offered classrooms in the new wing of the high school.
Which of the following is an assumption that enables the conclusion above to be properly drawn?
(A) Teachers in the new wing who eat their lunches in the cafeteria should keep their assigned classrooms
(B) Teachers with tiled classrooms should not eat in their classrooms, even though the new district policy permits them to do so.
(C) Teachers with carpeted classrooms should be allowed to eat in their classrooms
(D) The district policy should allow all teachers who want to eat in their classrooms an equal opportunity to do so, regardless of original classroom assignments.
(E) The district policy should minimize potential damage to school property, such as that caused by food stains in carpet.
With assumption based CR questions, one thing that the GMAT does to amp up the difficulty is to obfuscate the overall conclusion. In this case, the conclusion is that teachers who would
like to eat lunch in class should be assigned tiled classes. What the question has done with a subtle language shift is that it has put the onus on the school to cater to these teachers if possible. This is not indicated in premises, so we need an assumption that helps bridge the gap.
A - if A is true, it actually makes the conclusion less viable
B - So what? Makes no sense in the context
C - This actively attacks one of the premises, and if true, makes the conclusion less viable
D - This option actively makes the link between the rules about eating and whose responsibility it is to ensure positive outcomes within the framework.
E - This is a trap answer. Maybe it is something the district should do, but it only reiterates the goal of the first premise (that only teachers in tiled classrooms can eat food in class). It being true or not doesn't impact the argument in any way whatsoever.
Remember that when looking to find the assumption, the assumption being true makes the argument
possible. The assumption, if false, should make the argument
invalid
