choices.text: infirmary:doctor:rest soccer field:football:referee fridge:luncheon meat:refrigerate teacher:classroom:teach classes
explanation: "libraries" can "keep" "books". the function of an "infirmary" is to provide medical services, not a place for "doctors" to "rest". a "referee" gives a penalty for a "soccer" game on a "soccer field". the "refrigerator" can "refrigerate" "luncheon meat". the "teacher" "teach classes" in the "classroom", and the location of the "class" is the "classroom".
