Which of the following best explains the meaning and purpose of the following phrase from paragraph 29: “the same mill that grinds out the extra rich is the mill that will grind out the extra poor”? A The phrase connects the rich and the poor through the “mill,” implying that the two groups are not so different and thus contributing to the central theme of equality. B The phrase shows the rich taking advantage of the poor working at the mill, supporting the author’s claims that the rich knowingly take advantage of cheap, poor labor. C The phrase means the same “mill,” which represents U. S. industry, creates the very wealthy and the very poor, contributing to the author’s main argument for economic social reform.
