I got this after really looking at my conditional but I just don't understand how they expect us to take one for the other in a times setting?!?
R -> NR
~NR -> N
Obviously the first track doesn't have N before it, so it is N. But at first glance I thought that generally the last track comes before the first, and therefore since we deducted that track 7 is a N, then track 1 can be either N or R.
