But for the last question;

*If two rows of a determinant are interchanged, what is true of the resulting determinant?*

I wouldn't put the "If the two rows are an *even* number of rows apart, the value of the determinant is unchanged." part Soroban's answer (no offense), because our textbook simply doesn't cover it. That chapter really only discussed 3 x 3 determinants. Look at chapter 16-8 *Properties of Determinants *(page 798) Property 3

*"If two rows (or two columns) of a determinant are interchanged, then the resulting determinant is the opposite of the original determinant*."

Even though that's not true for all determinants as Soroban pointed out, that's how they want you to answer D':
