While it doesn’t look much different than 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 like a palm pilot. a coach or professional trainer monitors the device during practices or events held when temperatures and heat indexes are particularly high. if an athlete’s 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. to a reader understand the monitoring device for thermometer pills, the author uses a) a metaphor to show the cost of the device. b) a simile to compare the device to a palm pilot. c) personification to explain how the device works. d) hyperbole to stress the importance of the device.
