Q: Passage: At a major lunar standstill, which takes place every 18.6 years, the declination range of the Moon reaches a maximum. As a result, viewed from high latitudes, the Moon's greatest altitude (at culmination, when it contacts the meridian) changes in just two weeks -- from high in the sky to low over the horizon.

Question: Based on this passage, when the moon's declination is maximum north which of the following will occur?
