Testing Error on 96 physics gre?

  1. Oct 8, 2009 #1
    On problem number 77 on the 1996 Physics GRE test that is now available for practice, I believe there are two answer choices that are completely equivalent.

    The test is here:
    http://www.stanford.edu/group/sps/files/GR9677.pdf [Broken]

    I think answer choice (d) reduces down to choice (b), and I don't see anything barring me from making the algebraic simplifications. Is it really possible that ETS made a mistake that hasn't been found/reported or am I missing something?

    Thanks for the help
