So if we go by what was said in that chapter, and only what was said there, then the only natures that are made up by combining two basic natures are wood and ice. Because no other advanced nature was mentioned by Kakashi in that chapter, right?

I only care about the first of those pages, by the way. The other stuff doesn't matter. "By controling the nature of "X" and "Y" at the same time, he creates a new "XY" element which he can then manipulate." is the framework for how advanced natures are created, you can apply any two basic natures to it. But Yin and Yang aren't part of these five basic natures. They weren't in Yamato's explanation and when Naruto asked about them (indirectly), Yamato even said to postpone that explanation. It's more than obvious, man. This isn't some scientific research with the safety of the world on the line or so, so don't make this so hard for yourself, man. Because as I said, in the end, it's not up to you to decide, this is still a community thing.
