Could you explain what you mean by "factual"? Do you mean that it's true in the real world? Or true according to the passage? If it's the former, there are many that are real-world-true, because the majority of RC passages come from real scientific or historical facts. If the latter, every correct answer choice will be true according to the passage.

Or did you mean - are there any wrong answer choices that are in fact factual? This could certainly be the case. If you had an answer choice that said "the earth orbits around the sun," but the passage didn't tell you that, it would be real-world-true, but not a correct answer, because you didn't infer it from the passage.

If you clarify your question, I'd be happy to explain further.
