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 correct answer is - When studying mythology, I learned about several gods and goddesses: Zeus, Apollo, Aphrodite, Hermes, and Hercules.

This is the only sentence which is punctuated correctly because the first part (before the list) ends abruptly; it is obvious that something needs to be placed there. In this case, that is a colon.

The other sentences have leading words (particularly, such as, were) that don't require a colon after them.

Answer 2

There were several scientific processes I wanted to learn about such as, photosynthesis, diffusion, and osmosis.Run-on sentences are also called fused sentences. It has at least two parts, either one of which can stand by itself meaning; two independent clauses, but the two clauses have been smooshed together. Run-on sentences contain many ideas but they have no proper punctuation marks. Comma- splice on the other hand is different.  It is composed of a run-on sentence or two independent clause connected only by comma. In Grammar, sentence fragment is just a part of a sentence, meaning it is a group of words which has no complete thought while subject complement is an adjective, noun or a pronoun or a predicative expression that follows a linking verb.
