Answer: Med kit, Flash light, rations.
Explanation: Med kit: Just in case someone were to get hurt, you would need the med kit since you can’t go out to a hospital.
Flash light: In most cases when a hurricane happens, the power shuts off and to have the ability to see you would need to use a flash light.
