The correct answer is: It is more easily understood by the reader.
When Thomas Jefferson gave the speech on The Declaration of Independence he had appealed to the people by giving them something that's clearly understandable and something that they can agree or disagree to on some degree.
Thomas Paine on the other hand was not specific on the speech and gave jargons and stories that only he and the government can understand and not of the people.
Jefferson's appeal is more effective because he understood the plight and the sufferings of his people, and that freedom is something that all humans can achieve in any society to which they belong to.
