Answer: Based on the text, I believe hypothermia means having too low of a body temperature.
Hope this helps :)
Step-by-step explanation:
In the text, it says that the boy was pulled out of a frozen lake. That sentence already tells me that he's going to be really cold.
The prefix "hypo," means "under," or "below."
The root of "therm," can also mean "heat."
The suffix "ia," can be used in relation to a condition.
After it mentions that he was going into hypothermia, the text said that his body temperature was dangerously low.
