What should Benjamin do after identifying that Cole may be getting cold?

Covering Cole with a blanket or extra clothing is the appropriate action to take when someone may be getting cold. This approach helps to retain body heat and provide warmth, which is crucial in preventing further cooling and potential hypothermia. When a person is showing signs of becoming cold, it's important to act quickly in order to maintain their body temperature.

While other options may seem appealing, they do not address the immediate need for warmth that Cole requires. Leaving him to cool off would only exacerbate the situation by allowing his body temperature to drop further. Giving him cold water could be harmful, especially if he is already experiencing signs of cold; hydration is important, but it should be warm fluids if he is feeling chilly. Asking if he wants to go for a walk could be counterproductive, as physical activity might not effectively warm him up if he is already showing signs of hypothermia. Hence, providing extra layers through a blanket or clothing is the best method to help protect his body heat.
