1. A The entire track line is to the west of the Northern Hemisphere vertex.
2. B Military exercises being carried out within a 150 mile radius of LAT 47°10'N, LONG 137°30'W will interfere with  the proposed track line.
3. C Distance is measured by determining the length of a line in minutes of arc from the midpoint of the track to the point  of tangency.
