The topic is the perfect world

The world isn't perfect because no one is perfect. There is no perfect person, no perfect flower, no perfect animal, nothing is perfect. We maybe say "We are perfect" but we all are different from human to animal to plant ot everything.

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
