A line contains the points A, B, C, and D. Point B is between points A and C. Point D is between points C and B. Which of the following inequalities must be true about the lengths of these segments?
The correct answer is E.
There are many different arrangements of points that satisfy the conditions. But, in all of these, the order of points starting from point A is A, B, D, C.
Because D is between C and B, distance CD is always shorter than distance BC. So, CD < BC.
