I found this really hard because I still can't see why C is bad or even worse than D? D is saying that all the shows last year that were cancelled were police drama. C is saying that none of the ones that were renewed were police dramas.

To me, it seems C is stronger. If someone were to tell me D, I would naturally feel that the possibility that all their unpopular shows were police dramas still doesn't foreclose the possibility that some specific police dramas were quite popular. Maybe a lot of police dramas did really bad and got cancelled, but one or two also did really well! In that case, the fact that their shows this year are police dramas isn't necessarily a bad thing; maybe they'll be popular again! But with C, that latter possibility is totally closed. It shows us that no police dramas were popular last year.

I'm also displeased with this. I'm not doing any drills other than the ones integrated into the lesson plan, and after just finishing the MSS module, I checked the available practice tests and see that in the new format there are a few tests for which I've already seen 5 questions before.

Obviously, that's not a huge number, but it is not insignificant either in a test like this. Since the change to the new format, we have a reduced number of practice tests. It would've been more beneficial if all sample questions in the lesson curriculum itself were taken from the obsolete practice tests, rather than thinning out the already finite number of practice tests available.
