Limiting gradient for locating the base line on evenly-sloping ground, is A. 1 in 12 B. 1 in 10 C. 1 in 8 D. 1 in 6

The correct answer is: A. 1 in 12

The limiting gradient for locating the baseline on evenly-sloping ground is 1 in 12. This means that for every 12 feet of horizontal distance, the ground should rise or fall by 1 foot. This gradient is necessary to ensure that the baseline is level and that the survey data is accurate.

Option B, 1 in

10, is too steep and would result in inaccurate survey data. Option C, 1 in 8, is also too steep and would be difficult to work with. Option D, 1 in 6, is too shallow and would not provide enough accuracy for most surveys.
