I am interested! Taking in April

#help I have a question for the correct Answer Choice B for Question 6. How do we know that the conclusion reached by Wheeler has not been considered credible given the fact it is "a long standing theory" that "still inhibits history books"?

I think what I realized is that we know what the ranking is, i.e., more readers choose Bible over 1984. But we will need the number of readers choosing 1984 (or not choosing 1984) to jump from a ranking to a number, which then will allow us to make inferential statistics on whether, depending on the sample of 1,000, the number of all readers who find 1984 influential is a great number.
