Read this student's rough draft. The holiday weekend driving had been slow, and Myra was cramped in the backseat with her little brothers. At least she had a window seat. She had read for 100 miles, a painfully slow three hours, and she needed a diversion. She looked out the window and watched the green mile markers slowly tick by. She saw signs for the Tri-Cities Beltway and wondered what they might encounter.

What sentence would best add descriptive details to the end of this paragraph?

A.) The Tri-Cities Beltway had been constructed to alleviate traffic for three cities, but the merge was always problematic.
B.) The car slowed to a snail’s pace, and the line of cars ahead stretched out of sight, with exhaust fumes looming overhead.
C.) Myra reached into the backseat cooler and found a sandwich and a soda her mother had packed.
D.) The Beltway was a direct path back to their town, and Myra’s family had only 35 miles left to travel.
