Query: Primordial Abundances of ^6Li, ^9Be, and ^11B with Neutrino Degeneracy
  and Gravitational Constant Variation   Recent measurements of deuterium abundances from QSO absorption spectra show
two conflicting numbers, which differ by an order of magnitude. Allowing the
neutrino degeneracy together with gravitational constant variation at the epoch
of primordial nucleosynthesis, the implication of these observations on the
^6Li, ^9Be and ^11B abundances will be discussed. Within the permitted ranges
consistent with D, ^4He and ^7Li, we observe the strong \eta dependence of ^11B
as in SBBN but no significant dependence of ^6Li and ^9Be on the baryon number
density is observed. The predictions of ^6Li and ^9Be for low and high
deuterium differ by an order of magnitude and predictions for ^11B differ by
several orders of magnitude at most and vary with \eta.
