Improving logical fallacies and clarity
A logical fallacy is a flawed way of reasoning that ends up invalidating an argument. That is what we have in sentences 4, 5, and 6, where the author of the passage makes statements for which he does not have evidence and then moves on to making more claims based on those statements.
Sentences 4, 5, and 6 also hinder clarity. The author moves from a logical argument in the previous sentences to a less logical one in 4, 5, and. So, it is unclear what he is trying to say.
With the information above in mind, we can choose sentences 4, 5, and 6 as the ones that should be removed or revised.
