1. The point on the celestial sphere vertically below the observer's position, is called

2.  A. zenith B. celestial point C. nadir D. pole.   3. The parallax equation is applicable to entire overlap of the photographs only if parallax is measured

4.  A. normal to base line B. parallel to base line C. both (a) and (b) D. neither (a) nor (b).   5. The stereo plotting instruments are generally manufactured on the principle of

6.  A. optical projection B. optical mechanism projection C. mechanical projection D. all the above.   7. Latitude of a place is the angular distance from

8.  A. Greenwich to the place B. equator to the poles C. equator to the nearer pole D. equator to the nearer pole along the meridian of the place E. none of these.   9. International date line is located along

10.  A. standard meridian B. Greenwich meridian C. equator D. 180° longitude E. none of these.   11. The shortest distance between two places measured along the surface of the earth, is

12.  A. length of the equator between their longitudes B. length of the parallel between their longitudes C. length of the arc of the great circle passing through them D. none of these.   13. The correction for parallax, is

14.  A. - 8".8 cos α B. + .8" sin α C. + 8".8 cos α D. - 8".8 cos α.   15. The angle between the plane of the equator and the plane of the ecliptic, is known as obliquity of the ecliptic and its value is
