Allow choice C to also be an answer for question 2.

On our most recent test question, 2 has to deal with a magnet being dropped, when a magnet is dropped the magnetic domains move apart weakening the magnet, though the answer of weakening the magnetic field is wrong rather than B (re-aligning the magnetic domain). This has been proven by scientific institutes (See http://www.iop.org/activity/outreach/resources/pips/topics/forces_magnets/safety/page_42964.html for more details)
