What is exploratory quest?​

Explanation:

Definition Exploratory testing is simultaneous learning, test design and test execution Unlike the scripted testing, here the tester actively controls the design of the tests as those tests are performed, and uses information gained while testing to design new and better tests.

you didnt put the link on, so i cant read the paraphrase

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.
