Which of the following best fits in the blank?Cells are considered the foundation of life, but viruses―with all their genetic diversity―may share in that role. Our planet’s earliest viruses and cells likely evolved in an intertwined and often symbiotic relationship of predator and prey. Evidence even suggests that viruses may have started out as cells but ________________________. This dependent relationship began a long history of coevolution. Viruses living in cells cause their hosts to adapt, and those changes then cause viruses to adapt in a never ending cycle of one-upmanship.
1
injected many primitive characteristics into early cellular ancestors
2
lost their autonomy as they evolved to thrive as parasites on other cells
3
transmitted to humans via saliva in a mosquito’s bite and gotten independent from them
4
handed over through a cell’s membrane by using receptors and continually modified
5
exposed to a weakened virus and recognized that specific invader
해설
빈칸에는 “lost their autonomy as they evolved to thrive as parasites on other cells”(다른 세포의 기생체로 살아가도록 진화하며 자율성을 잃었다)가 알맞다.
빈칸 다음 문장의 “This dependent relationship”(이 의존 관계)이 받을 내용이 빈칸에 필요하고, “started out as cells but”는 세포였다가 달라졌다는 변화를 예고한다.
- “injected many primitive characteristics into early cellular ancestors”: 의존 관계로의 변화를 설명하지 못한다.
- “transmitted to humans via saliva in a mosquito’s bite and gotten independent from them”: 독립을 말해 “dependent relationship”과 어긋난다.
- “handed over through a cell’s membrane by using receptors and continually modified”: 세포막 통과 과정일 뿐 세포에서 바이러스로의 변화와 무관하다.
- “exposed to a weakened virus and recognized that specific invader”: 면역 반응에 관한 내용으로 문맥과 무관하다.
