과천외고 영어 어휘 오답: 아는 단어인데 틀린다면 원인과 결과의 방향을 보세요 실전문제

A gallery replaced its old lamps with models that used half as much electricity per lamp-hour. The staff expected the lighting bill to fall. Instead, the gallery doubled its opening hours and opened an additional exhibition room with the same number of lamps as its original room. All lamps operated throughout opening hours, and electricity prices stayed unchanged. Total lighting electricity use consequently rose even though each lamp had become more efficient. The improvement at the device level was real; the expansion in use was also real. Describing the rise as proof that the new lamps were inefficient would confuse energy per unit of service with energy used across all services. The relevant question was how efficiency and the scale of operation combined.

The relevant question was how efficiency and the scale of operation combined.

A gallery installed efficient lamps that ① reduced electricity use per lamp-hour. Longer opening hours ② increased the time each lamp operated, and a new room ③ added more lamps. These changes ④ offset the savings expected from efficiency alone. Because the gallery used more lamp-hours overall, its total lighting consumption ⑤ declined, as the meter's higher reading confirmed.
