Final answer:
The roofing crew was efficient but not effective. (option a)
Step-by-step explanation:
Efficiency refers to doing something in the most economical or fastest way possible, while effectiveness refers to achieving the desired result. In this scenario, the roofing crew was efficient because they completed the roof in record time, but they were not effective because they ended up reroofing the wrong house.
However, effectiveness is about achieving the intended goal or outcome. Discovering that they had reroofed the wrong house highlights a lack of effectiveness because the crew failed to meet the primary objective of roofing the correct house.
For example, if they had taken their time to confirm they were at the correct house before starting the job, they would have been both efficient and effective.
Darlene's roofing crew can be described as efficient but not effective. They completed the task quickly (efficiently) but failed to achieve the correct outcome (not effective).
The correct answer is a) efficient but not effective.
