Final answer:
The chapter provides evidence that the plan to release Jim is little more than a game to Tom.
Step-by-step explanation:
In the chapter of Huck Finn, there are several pieces of evidence that suggest the plan to release Jim is little more than a game to Tom. One piece of evidence is when Tom insists on making the escape plan as complicated and unrealistic as possible, even though a simpler plan would suffice. This shows that Tom is treating the situation as a game or adventure rather than a serious matter. Another piece of evidence is when Tom includes unnecessary and dangerous elements in the plan, such as snakes and spiders, which serve no practical purpose but only add excitement and drama to the situation. Finally, at the end of the chapter, Tom admits that he already knew that Jim was already a free man but wanted to carry out the elaborate plan anyway just for fun.
