Query: The Chemical/Dynamical Evolution of the Galactic Bulge   The last decade has seen apparent dramatic progress in large spectroscopic
datasets aimed at the study of the Galactic bulge. We consider remaining
problems that appear to be intractable with the existing data, including
important issues such as whether the bulge and thick disk actually show
distinct chemistry, and apparent dramatic changes in morphology at Solar
metallicity, as well as large scale study of the heavy elements (including
r-process) in the bulge. Although infrared spectroscopy is powerful, the lack
of heavy element atomic transitions in the infrared renders impossible any
survey of heavy elements from such data. We argue that uniform, high S/N, high
resolution data in the optical offer an outstanding opportunity to resolve
these problems and explore other populations in the bulge, such as RR Lyrae and
hot HB stars.
