Answer 2

Explanation:

Scientific research can change our lives for the better, but it also presents risks – either through deliberate misuse or accident. Think about studying deadly pathogens; that's how we can learn how to successfully ward them off, but it can be a safety issue too, as when CDC workers were exposed to anthrax in 2014 after an incomplete laboratory procedure left spores of the bacterium alive.
