Hi @shiyi-zhang,

Thanks for the question! We’re looking here for a flaw in the argument. Take a look at the first part of the first sentence of the premise. We are told there that high cholesterol levels have been associated with the development of heart disease. This presents evidence that at least for some people, high cholesterol can contribute to heart disease. But it then ignores this evidence, concluding that there’s no reason to make dietary changes to help prevent heart disease. Hope this helps! Feel free to ask any further questions that you might have.
