What does the third bubble say here? I glanced over some grammar structures that use なり but I don't know what it does in this situation. It doesn't help that 教わる is pretty new to me and that it seems fairly weird. It appears to be grammatically transitive but with a intransitive meaning. I am not even sure if what I just said makes any sense. At any rate I get that the second half talks about how it's better to study together but I am unsure about the first one.
