2. What is special about chameleon’s eyes?
A) Chameleons have got two eyes of two different colors.
B) Chameleons’ eyes are bulging, but they cannot track two different objects with each eye.
C) Each of Chameleons’ eyes has a different role; the tracking eye and the converging eye.
D) Chameleons’ converging eye sometimes will diverge from the tracking eye.

Many fish and birds have eyes on opposite（相反的） sides of the head, and they seemingly（表面看起来） have at any given moment two different pictures of the world around them. But chameleons’（变色龙） eyes are slightly（轻微地） bulging（突出） so they can focus both eyes on one object or track two different objects with each eye. The puzzling（费解的） question was: does one eye know what the other is doing? Scientists at Haifa University, in Israel, tried to find the answer with the help of a computer screen. We found out that each eye has a different role. We have the tracking eye, that will continue tracking the target, and the converging（汇聚的） eye that will converge to the tracking eye, and eventually she will choose that target. We found out that each eye has a different subtle（微妙的，巧妙的） pattern（模式） of eye movements according to her role.”
