Set Impact Limits Practice Test

A small town wants to reduce water use in a community center. Evidence: meter readings show water use is highest on days when the gym hosts tournaments, and staff report many faucets are left running in the locker rooms. Constraints: the center can close locker rooms for repairs only overnight, and it has $300 for changes this month. Staff agree trade-offs are required (convenience vs. reduced water use). Which option is a constraint that limits solutions?

A science class is trying to reduce energy-related air pollution from electricity use in their classroom. Evidence: a simple log shows lights and a projector are often left on during lunch, about 30 minutes per day. Constraints: the class cannot change the building’s wiring, and the custodian needs the lights on for 10 minutes after school for cleaning. The class agrees trade-offs are required (saving energy vs. keeping the room usable and safe). Which claim ignores the limits in this situation?
