Final answer:
It is false that drinking alcohol can help you stay warm in a blizzard; it actually causes your body to lose heat faster. The body conserves heat in cold environments by becoming lethargic, not by increasing blood flow to extremities.
Step-by-step explanation:
If you get trapped in a blizzard, you should not drink alcohol to stay warm. This is false. Alcohol may make you feel warm initially because it causes blood vessels to dilate, which can increase blood flow to the skin, but this is misleading. The increased blood flow to the skin leads to more heat being lost to the environment, which can actually lower your body's core temperature. Furthermore, alcohol can impair your judgement, making it more difficult to make wise survival decisions.
The correct response for C.J. stuck in her car during a blizzard would be that her body responds to the cold by b. becoming lethargic to conserve heat. This answer is consistent with the body's natural regulatory processes to reduce heat loss and conserve energy in cold environments.
