个人认为C选项并不是无关选项而是支持,Although Ketcham does not picture the struggle in quite this way, he does rightly see Jackson's tenure (the seventh presidency) as the culmination of the acceptance of party, commerce, and individualism. 在J的任期中,钱变得比用等价物交换更为普遍。直接支持作者对于J任期商业更为重要的观点,钱的更多使用表示了商业的色彩更浓(以物换物更多的是对必须品的需求,而不是商业化)。
