Are the following sentences CORRECT or INCORRECT? (it is asking about colons, semicolons, and commas)

. I wanted to eat donuts; so I went to Krispy Kreme.

. The new Star Wars movie should be awesome; therefore, I’m going to see it at midnight.

. Ms. Garcia’s favorite holiday is Thanksgiving; Brutus is obsessed with Christmas.

I'm not the greatest at grammar, but I think the very first one is incorrect. It should just be a comma, then the second just a comma as well, but the last one is correct. (I have no idea, I am sorry if you get it wrong.)

there is no passage what do you mean?

give me the passage and i will answer your question

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.
