Which word means "knowledge of something"?
A biologist
B discovery
C awareness
D environment

Awareness (C)

Explanation:

D would be eliminated because that just doesn't fit the definition.

Biologist (A) is a person and they do have knowledge, but another word would fit better. Plus, biologist has a different definition.

B would be finding out something. You will have a knowledge of it after to discover it. Plus discovery has a different definition.

This means C is the answer

Hope this helps!

answer: i feel like it would be group discussion

explanation:

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.
