I think you mean to say (A) here, and I'll proceed on that assumption

So "ALL" is a bigger idea, and "importance" is just one of some aspect of a story...right? But it still falls under the "all" category.
Why is what the argument saying is a flaw?
The key here to me is the difference between
important stories and
all stories, but not quite in the way I think you've interpreted it. One premise of the argument states that, "all sides of an
important story should be covered" and then states that "no newspaper adequately covers all sides of every one of its stories" (which is the
all reference). Now, if those two things are true (and we take them as such because they are premises), does that then allow us to infer that, "some
important stories would not be adequately covered" if only one paper existed? No, because it is possible for a paper to not cover all sides of every story but to still cover all sides of the important stories. They could do minimal coverage of the small stuff, and then do extensive coverage of the important stories. But the argument fails to take that into account when it concludes that some
important stories wouldn't be covered adequately. Do you see that shift there? That's a classic LSAT trick, and thus we have the flaw that, "The argument confuses the inability to cover all sides of
every story with the inability to cover all sides of any
important story."
Please let me know if that helps. Thanks!
