Answer:
A university's decision to add a new residence hall. A trucking firm's decision to move to a smaller facility.
Step-by-step explanation:
Short run decision affects variable factor only. Adding a new facility is a long run decision. Hence a firm's decision to decrease the amount of electricity used in day-to-day operations by encouraging employees to adopt conservation strategies is a short run decision.
Hence, the correct answer would be:
A university's decision to add a new residence hall. A trucking firm's decision to move to a smaller facility.
