Document A — Student proposal: Our school should try a quiet study hour twice a week. In a fictional survey of 30 volunteers, 22 said they wanted a place to work after class. The proposal says a staffed room could help these students begin assignments before going home. It suggests a six-week trial rather than a permanent change.

Document B — Office note: The room is available on Tuesday and Thursday, when a late bus already runs. Staffing still needs approval, and students who do not use that bus may have other transport needs. The survey did not ask how often respondents would attend. A trial should record actual attendance, staffing time and feedback from both users and nonusers before the school decides whether to continue.
