It's ***1/Adjective*** to sleep. But at MIT, only ***2/Number*** ***3/Plural Noun*** have enough ***4/Noun*** to actually do it. The rest of the ***5/Plural Noun*** prefer to ***6/Verb*** (or even ***7/Verb***!). This makes them behave like ***8/Adjective*** ***9/Plural Animal***, but Phys Plant tries to ***10/Verb*** regularly. In emergencies, Chuck Vest is available to provide ***11/Plural Noun*** for those who can't ***12/Verb*** themselves.
