7-44. Two points, A and B, are 125 feet apart. A 100-foot contour passes through  point  A and  a  125-foot contour passes through point B and the slope is uniform. How far from point A, to  scale,  should  you interpolate the 115-foot contour? 1. 15 ft 2. 50 ft 3. 75 ft 4. 115 ft 7-45. When drawing contour lines by using control points, what must you do to locate  contour  lines? 1. Scale 2. Interpolate 3. Average 4. Randomize 7-46. An area on a topographic map where contour lines are evenly spaced and wide apart represents a 1. valley 2. gentle, uniform slope 3. steep,  uniform  slope 4. ridge 7-47. In what direction does the curve of a contour line cross a stream? 1. Upstream 2. Westward 3. Downstream 4. Eastward 7-48. Contour lines represent what in relation to the earth’s surface? 1. Horizontal  planes 2. Vertical planes 3. Grid  lines 4. Different points of elevation 7-49. A  panoramic  sketch  shows  the terrain  in  what  manner? 1. In  contour  lines 2. In  elevation 3. In  perspective 4. Both 2 and 3 above Learning  Objective:  Recognize appropriate  scale  for  topographic maps; identify correct design and placement  of  topographic specifications. 7-50. Which of the following scales represent  a  large-scale  topographic map? 1. 1 in. = 50 ft 2. 1 in. = 120 ft 3. 1 in. = 500 ft 4. 1 in. =   1,000 ft 7-51. Which of the following contour intervals  should  you  use  to  prepare an  intermediate-scale  map  of  a hill? 1. 1 ft 2. 2 ft 3. 10 ft 4. 20 ft 7-52. Which of the following operations is NOT one of the basic operations for  construction  of  a  topographic map? 1. Plotting  horizontal  control 2. Plotting  details  and  ground points 3. Determining  slope  distances 4. Drawing  contour  lines 7-53. What lines are drawn before the actual  contour  lines  are  plotted  on a topographic map? 1. Spur and ridge lines 2. Vertical  control  and  spur  lines 3. Spur  and  valley  lines 4. Ridge  and  valley  lines 7-54. For clarity on small-scale maps, how  should  buildings  and  other features  be  shown? 1. To scale 2. Larger than scale and true to shape 3. Larger than scale and by symbols 4. By location in the notes 50
