G友们好，非常感谢帮忙！
此题好绕：
题干第一句话是说“客户买单时，当账单放在一个有信用卡logo的托盘里时，用【现金支付】给的小费更多”对吗？【问题1】后一句是：“这个logo使得有信用卡的客户想要消费更多因为暗示他们可以刷卡消费不受身上现金限制”，对吗？ 【问题2】这2句话的逻辑关系很奇怪。
问题是问增强：B项是题干后半句的逆否命题，所以是加强，对吗？【问题3】
D项怎么分析【问题4】：OG答案说是削弱，还说“Patrons using credit cards are surely aware that they have credit, and yet they spend less generously.”不理解。也请帮忙分析下OG这个答案【问题5】
