Carbon dioxide emissions are contributing to climate change, which is causing average global temperatures to increase. These temperature increases have led to a loss of sea ice in the Arctic. Populations of polar bears, which depend on sea ice as part of their habitat, have declined as a result of this loss. The rate of Arctic sea ice loss is predicted to increase if the current temperature trends continue. What is the best long-term solution to help maintain polar bear populations?

Which of these statements  mostaccurately characterizes linear perspective?   a. having learned that distant objects tend to be closer together, we interpret a two-dimensional image on the retina in three dimensions. b. we learn to compensate for the monocular disparity between the retinal images of the left and right eye. c. through experience, we determine that changes in images focused on the retina occur as a result of the motion of our bodies. d. as we view a landscape, the relative sizes of objects are revealed by texture gradient cues.
