The answer is: C. sentence 3
In the paragraph about Thomas Paine, sentence three must be revised because it contains a comma splice, which is the wrong use of a comma to separate two independent clauses. It can be corrected by adding a conjunction after the comma, by joining the clauses with a semicolon, or by writing separate sentences.
Therefore, the sentence can be revised in three ways:
- Franklin helped Paine move to Philadelphia, where he pursued a career in journalism, and he became the editor of Pennsylvania Magazine.

- Franklin helped Paine move to Philadelphia, where he pursued a career in journalism. He became the editor of Pennsylvania Magazine.
