Base your answer on the diagram, which shows a model of the apparent path and position of the Sun in relation to an observer at
four different locations, A, B, C, and D, on Earth’s surface on the dates indicated. The zenith (z) and the actual position of the Sun
in the model at the time of the observation are shown. [The zenith is the point directly over the observer.]
