• ① Transforming Wild Salmon Into Productive Domestic Stocks
• ② Why Salmon Rivers Are Very Long Today
• ③ The Basic Principles Of Selective Fish Breeding
• ④ How To Successfully Raise Salmon For Food
• ⑤ Comparing The Growth Rates Of Different Animals

정답 ①

해설 'Transforming Wild Salmon Into Productive Domestic Stocks'는 다양한 강에서 온 야생 연어의 유전적 특성을 교배하여 생산성이 높은 양식 연어로 빠르게 개량해 낸 과정을 포괄적으로 나타내므로 적절하다.

• ① Genetic diversity within a single river system is often insufficient to sustain a long-term commercial salmon farming operation.
• ② The salmon farmers initially struggled to identify which of the forty river systems contained the most resilient fish populations.
• ③ But whatever the manifestation of difference that occurred in different species of salmon, the first salmon farmers realized that crossing and recrossing the specific families from the original forty rivers would result in salmon that grew faster.
• ④ Environmental factors such as water temperature and current speed dictate the survival rates of salmon during their migration cycle.
• ⑤ Farmers observed that wild salmon populations were rapidly declining due to the excessive harvesting of fish from northern rivers.

정답 ③

해설 앞 문장들에서 강마다 다른 환경적 도전 과제를 언급한 뒤, 이 문장이 역접(But)을 통해 이러한 차이에도 불구하고 양식업자들이 성장을 극대화하는 방법을 발견했음을 제시하며 글의 핵심 논지로 전환하는 역할을 합니다.

[주어진 글]
The initial selection of farmed Atlantic salmon took place from fish drawn from forty different river systems. Every salmon river has its own unique set of challenges to which fish must adapt.

(A) But whatever the manifestation of difference that occurred in different species of salmon, the first salmon farmers realized that crossing and recrossing the specific families from the original forty rivers would result in salmon that grew faster.

(B) And because salmon, unlike cattle and sheep, can produce many thousands of offspring in the course of their lives, once favorable individuals were found, just a few strong males and females could form the basis of a whole new race of highly productive fish. A domestic population could be created quickly that would be quite different from the initial wild ancestors.

(C) Some rivers are very long, like the Yukon, and require animals that can build up massive fat reserves in order to survive the extended journey. Others are very far north, with only a short season of warmer temperatures, and require a fish that can maximize growth, particularly during its younger phase.

• ① (A) - (B) - (C)
• ② (B) - (A) - (C)
• ③ (B) - (C) - (A)
• ④ (C) - (A) - (B)
• ⑤ (C) - (B) - (A)

정답 ④

Q11 요약문빈칸 다음 글을 아래와 같이 요약하고자 한다. 빈칸에 들어갈 알맞은 어휘를 주어진 철자로 시작하여 각 한 단어로 답안을 작성하시오.

Early salmon farmers improved their stock by (a)c____________ fish populations collected from diverse river systems, each possessing unique environmental (b)a____________. By leveraging the high (c)r____________ capacity of salmon, breeders could rapidly select and propagate favorable traits to establish a new, highly productive (d)d____________ lineage. This systematic breeding process allowed the farmed population to evolve quickly, resulting in fish that grew significantly faster and differed substantially from their wild ancestors.

정답
(a) crossbreeding - Early salmon farmers improved their stock by crossbreeding fish populations collected from diverse river systems, each possessing unique environmental adaptations.
(b) adaptations - Early salmon farmers improved their stock by crossbreeding fish populations collected from diverse river systems, each possessing unique environmental adaptations.
(c) reproductive [생식의, 번식의; 재생[재현]의; 복사[복제]하는] - By leveraging the high reproductive capacity of salmon, breeders could rapidly select and propagate favorable traits to establish a new, highly productive domestic lineage.
(d) domestic [가정의] - By leveraging the high reproductive capacity of salmon, breeders could rapidly select and propagate favorable traits to establish a new, highly productive domestic lineage.
