What is the elevation of hachure line A? 100 feet
50 feet
75 feet
125 feet

Because the incorrect answer was 100 feet (based on it being the first lower elevation than the last recorded elevation of 125 feet) And the question prior of What is the most likely elevation of X being 115 feet was also graded incorrect. Would the actual contour lines WITH the hachure lines ON THEM continue to elevate in C. I. 25 increments making the contour line that X is on, 150 feet and the contour line that A is on to be 175 feet? And then 125 feet would actually be the correct answer because it is the first lowest below 175 feet?
