Kevin knows that mice are nocturnal creatures. That is, mice sleep during the day and are active at night. However, Kevin wants his pet mice to be awake during the day and sleep at night because humans are not nocturnal. Kevin hypothesized that he could trick the mice into thinking that day was night if he kept them in a dark room when the Sun was up and thinking that night was day if he kept them in a well-lit room at night. After performing a few experiments, however, he was unable to get the mice to reverse their sleep pattern. Which of the following statements is true regarding Kevin's hypothesis?
