The Newton-Raphson method is like a math superhero - it can only save the day if the function is continuously differentiable. No kryptonite for this guy!

Does the Newton-Raphson method come with a guarantee of an error bound? That would be really useful, but I'm not sure it's true. Gonna have to think about this one.

Wait, why can't it be used for non-differentiable functions? That seems a bit too restrictive. I'll go with B on this one.

Hmm, I thought the Newton-Raphson method was all about finding the middle point. Guess I need to brush up on my numerical analysis.
