سوال ۲۳ کنکور ارشد ریاضی ۱۴۰۱

PASSAGE 2 (excerpt, second paragraph):

"Where we were once satisfied with two-dimensional representations of physical objects, we now demand and achieve topologically and analytically complete three-dimensional models. Furthermore, these models allow us to derive quickly and automatically any geometric property or attribute that the object is likely to possess. Obviously, appearance is not the sole concern of geometric modeling, so we carefully distinguish between analytical models and rendering. We also require a mathematical setting that allows us to calculate relationships between models—closest approach, intersections, shadowing, and so forth."

Select the best choice for the meaning of the underlined word "distinguish" in the second paragraph.
