What is the purpose of an ellipsis? A) to indicate text has been omitted
B) to make the reader think about a point
C) to end sentence powerfully
D) to emphasize a specific fact​

Usually either B or C. Can be A if it's used during quotes. [see explanation - question contains nuance]

Explanation:

Honestly, it depends. Usually, an ellipsis is used in speech to show that the character is thinking and drifting off. If it's in a non-fiction formal piece of persuasive writing, then it would be B. Otherwise, if it's an essay and it's used in a quote, it's A. Usually though, it would be C.

Depends on context.

to me i think class room sitting education is better. i do online school and i have not learned a think haha. when i sit in the classroom i just sit there and kind of pay attention but still i get so far ahead in the class when im doing online i have nothing else better to do but play video games and i sit in school and learn and have friends and just actually learn. when i'm doing online i sit here listing to music and get on and and look up the answers i guess that is my fault for being a cheater. but to be honest i think sitting in the classroom is better.
