Final answer:
Rachel's attitude toward class, as explained in paragraphs 6 through 9, is strategic and focused on her own gain, making her decisions based on others' actions.
Step-by-step explanation:
Paragraphs 6 through 9 suggest that Rachel's attitude toward class is pragmatic and strategic. Rachel's logic reveals her consideration on whether to contribute based on Samuel's contribution. She concludes that if Samuel doesn't contribute, then contributing would make her a fool; but if he does contribute, she sees an opportunity to benefit by not contributing herself.
This indicates a calculative approach to class participation, based on maximizing personal gain rather than collaborative effort.
