In the book, why does Grandpa say Roberta can't drive any further down the dirt road?

• A. It's too muddy
• B. The road is closed
• C. There's a fence blocking the way
• D. Roberta is low on fuel

Answer: (A)

The main idea here is judging whether it’s safe to go further based on how the road looks and how it will affect driving. Grandpa stops Roberta because the dirt road has become too muddy to drive on safely. Mud on a dirt road makes it easy to lose traction—the tires spin, the car can slide, and it’s very likely to get stuck. That risk of being stranded or damaging the vehicle is why he won’t let her continue. The other possibilities don’t fit the scenario described: there’s no indication that the road is officially closed, or that a fence blocks the way, or that Roberta is low on fuel. The emphasis in the moment is on the hazardous road condition and the need to avoid trouble by proceeding.
