Final answer:
In the experiment to test if a smaller car can accelerate faster, the independent variable is the car size, and the dependent variable is the car's acceleration.
Step-by-step explanation:
To determine if you can accelerate faster when you drive a smaller car, the independent and dependent variables need to be clearly defined. In the context of this experiment, the independent variable is the factor that you as the researcher manipulate, which would be the car size. On the other hand, the dependent variable is what you measure or observe, in this case, the acceleration of the car. Thus, the correct answer is A) Independent: Car size; Dependent: Acceleration.
