The term that describes the optical trick of swelling columns at midpoint, which was used in the design of the Parthenon is entasis.
If you take a look at the ancient Greek columns, you will see that they are a bit wider in the middle - so the column is not completely straight, but rather swells up in the middle so as to "correct the visual illusion of concavity." It was often used by artists in the ancient Greek times.
I’m sure this is a preference question but here’s how I would answer “I would visit and John Cage from Los Angles and I would simply want to visit him and ask him about his composition of 4’33 because this just a rest note for a long time and it’s funny because it’s still consider a compostion”
I would say b. but i am probably wrong so I wouldn't rely on my response
