MGMAT Problem (Advanced Quant)
#4-9
If a does not equal to zero, is 1/a > a/(b^4 +3)?
(1) a^2=b^2
(2) a^2=b^4
Thanks!
Spoiler:
The correct answer is A, but I think the answer should be E. Based on statement 1, a and b can have the same numbers but with different signs. Therefore, I think E should be the solution.

When I first read this question, I thought of "style" in the fashion sense. lol. GMAT could have made my life a lot easier on this question by substituting "type" for "style."
