University spokesperson: Most of the students surveyed at the university said they would prefer that the current food vendor be replaced with a different food vendor next year.
Conclusion (should)
We should rehire Hall Dining next year.
Evidence (since)
Other things being equal, we should adhere to the preferences of the majority of students.
Most students surveyed said they would prefer that the current food vendor be replaced with a different food vendor next year.
The only alternative to the current vendor is Hall Dining, which actually was the university's food vendor until this previous year.
Evaluate
Given that ... we're going to go with what most students want and that ... most students want to bail from the current vendor and that ... Hall Dining is the only alternative vendor, How could we still say ... we should not rehire Hall Dining next year?
This argument is pretty tough to fight, given the constraints put on us by the premises. If we're following what most students want (and if we assume the survey is representative of that), then we should switch vendors. And since Hall Dining is our only option for switching, then we would switch to Hall Dining.
But, there was something weird about learning that Hall Dining was the old vendor for this university. If they were the vendor up until last year, it makes us wonder why we switched away from them a year ago.
Did the prices changes? Was the university less happy about the deal they were getting? Or were the students unhappy with the quality of food or service they were getting? If Hall Dining was bad enough to bail from a year ago, does it really make sense to go back to it?
Goal
It's hard to know how to phrase our objection, but we need a way to argue that we shouldn't switch back to our old vendor. We'll probably either say the survey is problematic or that something would be different (in a worse way) if we were to revert back to having Hall Dining as our food vendor.
