Answer:
d.
Explanation:
the answer is d. The importance of constellations.
Constellations are useful because they help stargazers and astronomers recognise specific stars in the night sky. Today, constellations are less important than they were in Ancient History. In Ancient times, constellations were used to create and track the calendar so they knew when to plant crops and harvest them. Constellations were also used for navigation and to help sailors travel across oceans. Once you find Ursa Major, you can easily spot the Northern Star (Polaris) and by using the height of the Northern Star, you could figure out your latitude.
