this question will take some thought.
if you really do not like bears and wanted to live someplace on earth where you would never see the constellation ursa major (the big bear) (declination +55 degrees).
what range of latitudes of earth could you live where this constellation would never rise?
between 35 degrees north and 35 degrees south latitudes
south of 35 degrees south latitude
north of 35 degrees north latitude
north of 55 degrees north latitude

Explanation:

The declination of a celestial object determines the latitudes from which it can be seen. For a celestial object with a declination of +55 degrees like Ursa Major, it will never rise for locations south of 35 degrees south latitude. This is because the maximum declination visible from a latitude $\theta$ in the southern - hemisphere is approximately $-(90 - \theta)$. If we set $-(90 - \theta)=+ 55$, solving for $\theta$ gives $\theta = 35$ degrees south.

Answer:

B. South of 35 degrees South Latitude
