Well, you know what they say about assumptions: they can make "a" out of "u" and "me." But in this case, your assumption is correct! Sentence A indeed contains incorrect comma usage.

The correct version of the sentence would be: "They were able to prove, I believe, that Jesse James was killed in Missouri in 1882." By adding a comma after "I believe," it separates the clause and clarifies that the belief belongs to the speaker.

Good job identifying the punctuation mishap! Keep up the sharp eye!

The correct sentence should be: "They were able to prove, I believe, that Jesse James was killed in Missouri in 1882."

You are correct! Sentence A contains incorrect comma usage. The correct sentence would be: "They were able to prove, I believe, that Jesse James was killed in Missouri in 1882." The comma should be placed after "believe" to separate the dependent clause "I believe" from the main clause "They were able to prove." Good job on identifying the incorrect comma usage!
