Richard answers `` B '' or `` C '' to every question on his A-through-D multiple-choice test .
Since there are no bathroom breaks allowed during the test , Richard rushes through the 2-hour exam in 20 minutes , `` dialing down the middle '' ( i.e. , answering `` B '' or `` C '' to every question on the A-through-D multiple-choice test ) while disgusting the other test-takers with frequent flatulence .
