Question

Is it possible to make up for missed sleep on the weekends? Dr. Daniel Cohen investigated this prevalent belief by disrupting the circadian rhythms of a group of volunteers. Participants remained conscious for 33-hour stretches—equivalent to staying awake all night—and then slept for 10 hours. While the volunteers were awake, Cohen periodically tested their mental and motor skills. The sleep-deprived volunteers scored fairly well soon after waking, but as the hours wore on, the participants' ability to think clearly, as well as their reaction times, steadily worsened. The study implies that the chronically sleep-deprived may function normally for a short time but inevitably slow down, even if they attempt to catch up on their sleep.

The volunteers' performance eventually _________.

Answer 1

B deteriorated

Step-by-step explanation:

According to the given article, it is noted that Dr. Cohen made some experiments to see if a person that is deprived of sleep for a period of time is still able to function. The research question was to see if it was possible to make up for missed sleep on the weekends. He got some volunteers and they were allowed to go thirty three hours without sleep and then to sleep for ten hours, before being given some tasks to perform.

The study implies that the chronically sleep-deprived may function normally for a short time but inevitably slow down, even if they attempt to catch up on their sleep.

The volunteers' performance eventually DETERIORATED.

*For something/someone to deteriorate, it means that their performance or output got worse with time.
