Read the following premise and answer if the hypothesis is true.
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 earl. Is the answer "Yes", "No", or "It's impossible to say"? Respond with only the answer and no additional text.
It's impossible to say
It's impossible to say. The text in the premise does not provide any information about the author of the textbook.
