Question

Which sentence is punctuated correctly?

My father loved talking about history, particularly: the Civil War, the Cold War, and the Revolutionary War.
There were several scientific processes I wanted to learn about such as, photosynthesis, diffusion, and osmosis.
The only states that Marina had yet to visit were: Colorado, Wyoming, North Dakota, and Rhode Island.
When studying mythology, I learned about several gods and goddesses: Zeus, Apollo, Aphrodite, Hermes, and Hercules.

Answer 1

The fourth sentence is correct.

Why: it uses a colon properly to introduce a list after a complete independent clause. The others misuse punctuation:
- 1: remove the comma before the colon — or rewrite as "particularly the Civil War, the Cold War, and the Revolutionary War."
- 2: remove the comma after "such as" — "…about such as photosynthesis, diffusion, and osmosis." (Better: "…about processes such as photosynthesis, diffusion, and osmosis.")
- 3: omit the colon — "The only states that Marina had yet to visit were Colorado, Wyoming, North Dakota, and Rhode Island."
