난이도 중 20점2. 빈칸에 들어갈 말로 가장 적절한 것은?

A gardener first thought that using a bed for early lettuce meant losing the chance to grow beans there. She then learned that the lettuce could be harvested before the bean-planting season. This removed the assumed overlap in the bed's use. It did not, however, make her labor or water unlimited. Therefore, ______.

① the two crops must now have identical market values② the apparent conflict over that bed's timing had weakened, while other resource constraints still required attention③ planting beans had become impossible for biological reasons④ every cost of growing lettuce had disappeared⑤ the lettuce harvest would necessarily reduce the bean yield

난이도 상 25점3. 지문에 제시된 의사결정 기준으로 가장 적절한 것은?

Noah bought a ticket yesterday for a performance. The ticket cannot be refunded or transferred. Today he is offered a place in a free workshop at the same time. He would enjoy the workshop more, and traveling to either venue would take the same time and money. He says, 'I must attend the performance to recover what I paid.' His friend replies that attending cannot recover the ticket price.

① Attending the performance will return the ticket payment to Noah.② The workshop has no opportunity cost because it charges no admission.③ The past payment should be counted as a new additional cost only if Noah chooses the workshop.④ Noah must add the enjoyment of both events because he paid for one of them.⑤ With the payment unrecoverable under either choice and other stated costs equal, the future benefit of the available alternatives should guide this comparison.

난이도 수능 이상 40점4. 다음 상황에 대한 분석으로 가장 적절한 것은?

A bakery has one oven slot left. Using it for rolls would yield a contribution of 60 units after all additional production costs; using it for fruit loaves would yield 45. A cold dessert yields 20 and can be prepared separately without using the oven or competing labor. The bakery has already paid a non-refundable 30-unit inspection fee regardless of what it bakes. A customer now offers a 10-unit bonus if fruit loaves are made. There are no other differences in costs or benefits, and the bonus is in addition to the stated contribution. The owner considers fruit loaves because '45 plus 20 plus 10 is greater than 60.'

① The comparison is sound because cold-dessert income is available only with fruit loaves.② The inspection fee should be subtracted only from the rolls option.③ Fruit loaves now produce 75 units from the oven, so their opportunity cost is 45.④ The comparison incorrectly includes the independent dessert on only one side; rolls plus dessert yield 80, while fruit loaves with bonus plus dessert yield 75.⑤ The bonus eliminates the need to compare the two oven uses because it changes the original offer.
