More clues exist in
other parts of the skull. The jaw joint of carnivores such as dogs and cats has
the mechanical advantage of being at the same level as the tooth row, allowing
the jaws to close with tremendous speed and forcing the upper teeth to occlude
against the lower teeth with great precision. In herbivorous animals,
rapid jaw closure is less important. Because the flat teeth of herbivores work
like grindstones, however, the jaws must move both side to side and front to
back. The jaw joints of many advanced herbivores, such as cows, lie at a
different level than the tooth row, allowing transverse tearing, shredding, and
compression
of plant material. █If we extend such observations to extinct dinosaurs, we can
infer dietary preferences (such as carnivory and herbivory), even though we
cannot determine the exact diet. █ The duck-billed dinosaurs known as
hadrosaurs are a good example of a group whose jaw joint is below the level of
the tooth row, which probably helped them grind up tough, fibrous vegetation.
█Paleontologists would
like to be much more specific about a dinosaur's diet than simply
differentiating carnivore from herbivore. █This finer level of resolution
requires direct fossil evidence of dinosaur meals. Stomach contents are only
rarely preserved, but when present, allow us to determine exactly what these
animals were eating.
위와 같은 두 단락이 있고, 삽입되어야 할 문장은 다음과 같았습니다.
Unfortunately, studies of living animals provide only a very general understanding of what various dinosaurs ate.
인데요...실제 시험이었다고 가정하면,
단서를 어떻게 잡아야 하나요?
그냥 문장을 빈칸에 넣어보고 말되는지 읽어봐라 라고는 대답하지 않으셨으면 좋겠습니다. 그걸 모르는 것은 아니니까요ㅠㅠ
저는 우선 Studies of living animals가 앞에서 언급되어야 한다고 생각하기 때문에, 세번째 네모가 정답일 거라고 생각합니다.
근데 문제는 provide only a general understanding of what various dinosaurs ate라는 부분에 대해서 뒤에서 구체화 되어야 할 것 같은데....
좀 헷갈리네요//./ 답은 3번이 맞긴 한데...좀더 자세하게 섦명해주실 분 있으실까요??
