Which is the BEST rebuttal to the argument Socrates gives in paragraph 4? Take another example: Never, in nature or among man-made objects, do we find a perfect circle. Nonetheless, we are able to judge of this or that object that it approaches, or falls short of, an ideal circle. But where did we get this notion of an ideal circle, if we are born with an intellectual tabula rasa? No; this idea of the perfect Circle is innate in us, part of the knowledge with which we are born. A teacher is truly a Mentor, Homer’s character, whose name means "to cause to think." A teacher brings knowledge out of us; she does not put it in. Indeed, the very root of the word 'educate' means "to draw forth."

A) This argument is circular.
B) There is no such thing as a perfect circle.
C) Other geometric shapes are known to be perfect.
D) We could get the idea of a perfect circle from imperfect ones.
