Need help part 3

I don’t know where I went wrong. I need some help here. I’m so worried because I failed it the first time and I need to try again.

1: how can you tell if a 404 does not deserve Fails to meet? 2: the side-by-side question where there was a typo and I think it was for Krisa os instead of I think krita, Were the webpages that pulled up other Mac iOS things are supposed to be failed to meet? I thought they failed to meet because they didn’t answer the query.

3: if the result block is not the same, but the link turns out to be the same when it sends it to your phone, is that a dupe, or not?
