Mrs. Brown's class is studying how the path of the sun crossing the sky changes during the day. Each hour a pair of students go outside to a square Mrs. Brown has painted on the sidewalk. One student stands a ruler upright in the center of a painted square.

The paper is then posted in the classroom alongside the tracing made the hour before. What is the correct order of shadows traced by the students?

• A. A, B, C, D

• B. B, C, A, D

• C. D, A, B, C

• D. A, C, D, B
