And I thought my work was hard. This is a very stupid question because 2 points are between the marks, which confuses me because for A halfway between -.25 and -.5 is -.375, and for D the halfway point between -1.5 and -1.75 is -1.625. However, point A is shifted slightly to the -.25, causing it to be lower than -.375 and closer to -.3. On the other hand, point D is PROBABLY directly in the middle, making it the value -1.625, which is incorrect. For this reason, I think the answer is D.
