When the Pinecrest Animal Shelter, a charitable organization, was in danger of closing because it could not pay for important repairs, its directors appealed to the townspeople to donate money that would be earmarked to pay for those repairs.
Conclusion
Before the directors donate surplus funds to other animal shelters, they should obtain permission from the donors.
Evidence
The donors offered their money in response to important repairs that Pinecrest needed to make, or else it would be in danger of closing, but the shelter took in more than enough money to cover the repairs.
Evaluate
The conclusion we're trying to strengthen is that directors of the shelter should ask for permission before passing someone's donation on to another recipient.
After all, the donors thought they were contributing to necessary repairs for Pinecrest. They might not have offered money if they thought it was going to other animal shelters.
Goal
So we probably want something like,
if you're going to use donated money for a purpose that's obtain different from why the donors → permission offered their money in the first first place
Or the contrapositive,
The weird part of this question stem is that we're not only trying to justify this conclusion but also try to put the least restriction on how directors allocate funds. So we might have to worry if an answer choice is too strong / too restrictive.
