Explanation

Hi Marissa, thanks for the question This is a Parallel question that requires us to match the sufficient/necessary reasoning in the passage with the correct answer choice. The argument states that: Major earthquake in region -> Preceded by series of minor tremors It concludes: Preceded by a series of minor tremors -> Major earthquake in region This conclusion is a reversal of the information provided in the premises. Answer choice E does the exact same thing. Local outbreaks of this disease among humans -> Detection of high infection rates among local wildlife Therefore, detection of high infection rates among local wildlife -> local outbreak of this disease among humans. Same reversal. I hope this helps. Please let me know if you have any other questions!
