DQ responses for both DQ 1 and DQ 2, 3 RESONSES for EACH DQ

For the initial DQ responses, you’ll need to meet a word count of 200. This is NOT counting any citations, direct quotes, tables, math, agreement, compliment, or anything not directly related to your response that you have included in your DQ. Of course, the 200 words should be your own and not copy-pasted, direct quotes, or tables, even when a citation has been provided.
