For the illusion in art passage, was 'stalk' used to mean 'grab hold of' or to follow stealthily (the answer wasn't quite follow stealthily, but it was similar). I am pretty sure it was grab hold of, even though grab hold of isn't the definition of stalk. If you replaced 'stalk' with the stealthy/soft answer, it didn't make any sense.
For the university passage I said both authors agreed that the faculty's main job was intellectual teaching and what not. The first definitely though so, and the second actually said so. The only difference is that the second thought that they could also get students to work together for civics and other things.
