Which statement best describes credible internet source

1. where are the statements?

2. If i were to find a statement it should have someone who majors in that source (ex: the statement is about archeology; so the statement is from a well known archeologist)

what we learned: when reading a statement about a certain subject if someone who is a major in that subject has made a quote in the statement then it's more credible; when the statement gives evidence or facts that have been proven the statement is much more likely to be credible.

I hope you understand and if not show me the statements and i will re-answer the question for you.

answer; i believe that the correct answer is (north and south);
