(II) The mathematician, engrossed in the ___________________ problem set before him, remained ___________________ to the trivial distractions of the world outside.Solution
"Arcane" perfectly fits the context, referring to something known or understood by only a few, and "oblivious" fits well because the physicist is so absorbed that he is unaware of anything else. Thus, the best answer is (b) arcane, oblivious.
