Answer:
mania
Step-by-step explanation:
Based on the scenario being described within the question it can be said that Mr. Hoffman's behavior is most indicative of mania. This is a phase of bipolar disorder in which the individual begins to experience intense energy, rapid thoughts and other exaggerated behaviors that are not normal for the individual. Such as suddenly wanting to bet all your savings on a horse race, as is the case with Mr. Hoffman. Which is a behavior that is completely abnormal for him.
