Final answer:
The assumption made by the student cannot be determined based on the information provided.
Step-by-step explanation:
The question is about whether the assumption made by the student that presidents should stick to their promises can be supported. In this case, the assumption cannot be determined based on the information provided. Presidents often face high expectations to fulfill their promises, but they may not have full control over external factors such as the economy. The 2008 recession, for example, was a result of various factors beyond the control of the President.
