All works of art are beautiful and have something to teach us. Thus, since the natural world as a whole is both beautiful and instructive, it is a work of art. The reasoning in the argument is flawed because the argument
A: uses the inherently vague term "beautiful" without providing an explicit definition of that term
B: concludes, simply because an object possesses two qualities that are each common to all works of art, that the object is a work of art
C: attempts to establish an evaluative conclusion solely on the basis of claims about factual matters
D: fails to consider the possibility that there are many things that are both beautiful and instructive but are not part of the natural world
Choose A, B, C or D as your solution.
