1. The graphical illustrations mathematics teachers use enable students to learn geometry more easily by providing them with an intuitive understanding of geometric concepts, which makes it easier to acquire the ability to manipulate symbols for the purpose of calculation. Illustrating algebraic concepts graphically would be equally effective pedagogically, even though the deepest mathematical understanding is abstract, not imagistic. The statements above provide some support for each of the following EXCEPT: (A) Pictorial understanding is not the final stage of mathematical understanding. (B) People who are very good at manipulating symbols do not necessarily have any mathematical understanding. (C) Illustrating geometric concepts graphically is an effective teaching method. (D) Acquiring the ability to manipulate symbols is part of the process of learning geometry. (E) There are strategies that can be effectively employed in the teaching both of algebra and of geometry. _________________

IMO B is the answer. The stimulus talks about the deepest mathematical understanding and not 'any' as B states. Last sentence clearly says there is something more deeper than the graphical understanding, so A is supported in the paragraph and hence the choice is wrong.

IMO B

It is mentioned in the argument that "deepest mathematical understanding is abstract, not imagistic". Therefore, the pictorial understanding cannot provide the deepest understanding and hence cannot be the final stage. Hence, there is support for A

For A - Pictorial understanding is not the final stage of mathematical understanding. ( this point is supported , where the author is saying -acquire the ability to manipulate symbols for the purpose of calculation. that means calculation is the final step)

For D - acquire the ability to manipulate symbols for the purpose of calculation. - is clearly supported _________________
