Answer:
The President would receive this question:
a) Negatively, because it presumes that the president is to blame.
Step-by-step explanation:
Let's turn this situation around for a moment. Imagine that your car breaks suddenly and you call for help. The mechanic arrives, takes a look at your car, and asks you, "What have you done to break this car?" You would certainly receive this question negatively. The mechanic is blaming you for the car problem, even though he has no evidence that you caused it. Even if the question didn't anger you, it would still be annoying.
The same principle applies to the question asked to the president. He is basically being accused of being part of the problem. Even if that were true, the effect of such a question would be negative. President Roosevelt would probably feel attacked. His focus on solutions would be taken away, the audience now eager for a response concerning the implied accusation.
