Sheep and barn owls see in three dimensions (3D) by combining two images in their brains, one from each eye. This produces a sense of depth, helping the animals judge how close or far away an object is. Researchers have investigated 3D vision in praying mantises as well. In one study, Vivek Nityananda and his team fitted mantises' faces with two different color filters, one covering each eye, much like the filters in 3D glasses once worn at movies. By observing the mantises' reaction to projected images, the team confirmed that mantises do indeed have 3D vision, but it's unlike that of other animals.
Which choice best describes the overall structure of the text?
The text explains the general differences between the vision of sheep and barn owls, then introduces a study of praying mantises' vision.
A
The text discusses 3D vision in sheep and barn owls, then introduces a study about this kind of vision in praying mantises.
B
The text describes how sheep and barn owls see, then presents a study about praying mantises that challenges the accuracy of that description.
C
The text reviews the similarities in how sheep and barn owls see, then provides details of a study about praying mantises to confirm these similarities.
D
