1. A transit is oriented by setting its vernier A to read the back azimuth of the preceding line. A back sight on the preceding transit station taken and transit is rotated about its vertical axis. The vernier A reads
The directions of plumb lines suspended at different points in a survey are not strictly parallel
In surveys of small extent, the effect of curvature may be ignored and the level surface of the earth is assumed as horizontal
In surveys of large extent, the effect of curvature of the earth must be considered
All the above.

2. In geodetic surveys higher accuracy is achieved, if

3. In geodetic surveys higher accuracy is achieved, if
curvature of the earth surface is ignored
curvature of the earth surface is taken into account
angles between the curved lines are treated as plane angles
none of these.

4. Determining the difference in elevation between two points on the surface of the earth, is known as
levelling
simple levelling

15. While working on a plane table, the correct rule is :
Draw continuous lines from all instrument stations
Draw short rays sufficient to contain the points sought
Intersection should be obtained by actually drawing second rays
Take maximum number of sights as possible from each station to distant objects.

16. Pick up the correct statement from the following
the contour lines having the same elevation cannot unite and continue as one line
a contour can not end abruptly, but must ultimately close itself not necessarily within the limits of map.
the direction of steepest slope at a point on a contour is at right angles to the contour
all the above.
