Question

Quizplus · Accepted Answer

When someone is dehydrated, they lose fluids which can cause a decrease in body weight. A weight loss of 2% or more of their body weight can indicate dehydration. In this case, a weight loss of 2% of John's starting weight of 185 pounds would be 3.7 pounds. Therefore, if John's weight drops to 181.5 pounds or below during training, he is very close to becoming dehydrated. Choice D) 181.5 is the closest weight to this threshold.
