#2:  Shadow Questions  answers.

1.  Since the shadow is so long it must be near sunrise or sunset (no way to tell which).

2.  Since the sun rises and sets in the east and west, and the road is parallel to the shadow, the road also runs east-west.

3.  If the shadow is the same length as the object, the sun is at a 45-degree angle (halfway between noon and sunrise or sunset).  As the sun moves higher in the sky, the shadow will shrink.  As the sun moves lower in the sky, the shadow grows.  [Perhaps you will observe shadows this summer and think about all this!]
