#help I chose C. I chose C because I thought of it this way: "Why is public aware of the severity of the problem of contaminated water?" Well, the public is aware of this because they are aware of the most obvious health problem. And the stimulus confirms that the water presents a much bigger threat to the community, hence why they're more aware of it than they are of the ozone problem. I understand now why B is correct but could I get a bit more of an explanation for why it isn't C? I'm assuming it's because most obvious doesn't mean it's the biggest threat but I need more of an explanation.. Thanks!

Maybe this is touched on more in later lessons but I'm having a hard time understanding what he means by "don't attach the premise; attack the support" My understanding is that the premise(s) is/are the support for the conclusion. So, would I not be attacking the premise for these questions? I'm just a little bit confused on the difference between the premise(s) and the support? #help

Why hasn't there been any changes yet, despite there still comments of concern? Also, the word "malpractice" is misspelled within the video.
