3. <u>True</u>, as the known fact the earth rotates in anticlockwise direction hence the eastern side gets to see the sun first and western side later this rule applies everywhere in the earth on both the equinoxes.
4. <u>True</u>, The celestial poles and equator are two points on earth that represent the equinoxes and the point that falls directly over the poles is called the zenith and the plane that touches is called the galactic plane.
