11-32. In  profile  leveling,  rod  readings taken from points that are neither BMs nor TPs are entered under what heading  in  the  field  notebook? 1.   BS 2.   FS 3. IFS 4. Remarks 11-33. You have run a line of levels from an initial BM to a final BM. You compute  the  elevation  of  the  final BM to be 1,475.77 feet. The elevation of the initial BM is 1,502.36 feet. If the sum of the backlights is 16.32 feet, what is the sum of the foresights? 1. 10.27 ft 2. 26.59 ft 3. 32.06 ft 4. 42.91 ft 11-34. At what point(s) along a proposed highway  are  cross  sections  taken? 1. Every 25 ft 2. Every 50 ft 3. At regular stations only 4. At regular stations, at any point where there is a break on the ground, or at any interval  desired 11-35. By which of the following methods is the HI in cross-section leveling determined when using a hand  level? 1. By adding the instrumentman eyesight height to the center-line elevation from profile field notes 2. By adding the instrumentman eyesight height to a BM elevation 3. By adding the BS reading to a BM  elevation 4. Each of the above 11-36. You are doing cross-section leveling for a highway road survey. The profile center-line elevation at station 25 + 00 is 112.5 feet and eye height is 5.3 feet. On a rod held 20 feet from the center line you read 11.2 feet. What is the elevation at this point? 1. 96.0 ft 2. 106.6 ft 3. 118.4 ft 4. 129.0 ft 11-37. What is a form of differential leveling  in  which  a  continuous check is maintained on the accuracy of the leveling procedure? 1. Three-wire 2. Double rodding 3. Cross-section 4. Profile 79
