Final answer:
Mr. Epstein's advice to Alfred about boxing likely included tactics of agility, strategic psychological engagement, and possibly the mental and promotional aspects of the sport, reminiscent of the boxing styles and public personas of Muhammad Ali and Joe Frazier.
Step-by-step explanation:
The advice that Mr. Epstein gave Alfred about boxing can be deduced from the strategies employed by notable boxers Muhammad Ali and Joe Frazier, as detailed historical examples provide insight into successful boxing techniques. While the question does not provide specific details on Mr. Epstein's advice, one might infer that it revolves around the skills of agility and strategic psychological engagement akin to Ali's philosophy to "float like a butterfly, sting like a bee." This suggests being quick and elusive in the ring while maintaining the ability to deliver powerful blows when the opportunity presents itself. Furthermore, Ali and Frazier's iconic rivalries, such as their verbal sparring before matches, highlight the importance of psychological readiness and public promotion as aspects of the sport. In this context, perhaps Mr. Epstein's advice to Alfred could also encompass the mental and promotional sides of boxing, as demonstrated by these historical figures.
