Can we draw the following hypothesis from the context (see options)? 

Context:

Maybe we should ask. So if you're asking me if I feel it's enough or if it's -- I'm not sure what it is you're asking me about that. I feel, actually, that there are topics that probably could be explored in more detail, but I understand that there are limitations within any textbook that you have to hit on core concepts. I believe that core concepts are covered, but I think that, in my opinion, what I've looked at, it's historical context.

Hypothesis: textbook has been made by somebody named steve
OPT:
[i] Yes;
[ii] It's impossible to say;
[iii] No;
