Q: How to remove topics from apple news?

I like the new Apple News product for iOS.  However, it seems difficult to mange the topics.  I usually read headlines and other news using other apps.  My kids have iPads that are tied to my account and managed by me.  I would like to use the news product with them, but I cannot figure out how to restrict the news to just a few topics of interest to them (Science, history, etc). They do not care about Sports, Finance, fashion or any breaking news (nor do I want them to see much of it).  There seems to be no way to remove trending news, breaking news, or other mainstream stuff.  I can find no references on how to do it either.

Thanks in advance
