Question

shutting down. who is most at risk? surprisingly, it is younger athletes. often, they either do not recognize or ignore the warning signs until its too late. to make matters worse, childrens bodies are much less efficient than adults at cooling themselves. a promising new product hopes to end the all too common heatstroke trend. it is called a thermometer pill.
2 while it doesnt look much different from the average vitamin capsule, the work it does inside the body is truly amazing. once ingested, these capsules send an internal body temperature reading to a portable device that is not much bigger than an iphone. a coach or professional trainer monitors the device during practices or events held when temperatures and heat indexes are particularly high. if an athletes body temperature reaches a dangerous level, the monitor immediately transmits an alert. the player is then rushed indoors and placed in an ice bath to rapidly decrease his or her body temperature. this is important, since internal organs can begin shutting down at 105 degrees fahrenheit.
3 while these tiny lifesavers have proven to be effective, they are quite expensive. on average the cost is $50.00 per pill. however, many parents of young athletes say that it is a small price to pay for the peace of mind it gives them on a hot, sultry day.
4 why are younger athletes more likely to be at risk for heatstroke according to the article?
a they do not sweat as much as adults.
b they do not recognize the warning signs.
c they spend more time playing sports outdoors.
d their internal organs shut down at a lower temperature.

Explanation:

The text states "Often, they either do not recognize or ignore the warning signs until it's too late." This directly relates to option B. Option A about sweating is not mentioned. Option C about outdoor time is not in the text. Option D is incorrect as the text says internal organs shut down at 105 degrees Fahrenheit for everyone (not a lower temperature for younger athletes).

Answer:

B. They do not recognize the warning signs.
