1. I believe the answer is novel because for the other answer choices, you're able to advertise on there.
2. C because of course, advertisers would want to choose a place that is noticeable so that their ad gets seen.
3. I believe D, a documentary. Normally in documentaries, they're based on factual information.
4. D because you're able to find advertisements in all of the choices.
5. I'm unsure on this one. It's definitely not D though because it doesn't make sense. I would say the best choice is A.
6. I believe the answer is D. For example, the news are able to communicate a lot of information (such as CNN).
7. The best answer is D because if another person, especially one who's famous, advertises the product, that'll help the advertiser(s)' product become more well known and possibly have a higher demand for it.
