Final answer:
The barrier separating two roadways, including interstate highways, is known as a median. It is designed for safety to prevent vehicles from crossing into oncoming lanes. However, the safety of a rabbit crossing the freeway depends on numerous dynamic factors.
Step-by-step explanation:
The correct answer to the question is 1) Median. A median on a roadway is the area that separates two opposite lanes of traffic on divided roadways, including interstate highways. It can be made of grass, concrete, or other materials, and its main purpose is to enhance safety by preventing vehicles from crossing into oncoming traffic.
As for the safety of the rabbit crossing the freeway, it greatly depends on multiple factors such as traffic density, the speed of the vehicles, and the rabbit's speed. If the car is in the furthest lane from the rabbit, and there are two other lanes between the car and the rabbit with traffic moving, it is not safe to assume the rabbit can cross all 3 lanes safely. The rabbit has to face the risks of crossing each lane, and each vehicle's position and speed must be considered in regards to the rabbit's timing and speed of crossing.
