While moving along the ground, the flicking of a snake's tongue is an important sensory behavior.
Even though they have nostrils, snakes can augment their sense of smell by sticking out their tongue
to essentially taste the air. [ ] An even more interesting thing is that the tip of their tongue is widely
separated into two distinct parts, which allow the snake to have more surface area in contact with
the chemicals in the air. [ ] After picking up odor particles from the air, the tongue is retracted to the
vomeronasal organ (also called Jacobson's organ), a secondary olfactory sensing organ in the roof
of the mouth, delivering chemical stimuli gathered and sending the information to the brain, allowing
the animal to taste the scent particles, find food and identify potential mates or enemies. [ ] The
deeper the fork in a snake's tongue, the more the snake can use its Jacobson's organ. [ ]
Another reasons snakes have a forked tongue is so that the tongue can touch the two pits in this
organ.
저는 이 문제에서 주어진 문장의 in this organ에서 this organ이 바로 앞 문장에 나오는 Jacobson's organ
을 받는다고 생각을 하고 네 번째를 골랐거든요. 어떤 점을 잘못 생각한 걸까요? 그리고 세 번째 칸이랑 헷
갈렸는데 세 번째가 답이 되려면 앞 문장에서 주어진 문장의 the two pits를 받는 부분이 있어야 할 것 같은
데 그런 부분이 딱히 잘 찾아지지도 않았고요ㅠ 앞 문장이 너무 길어 그런지...
