You are prepared for the trip, with a state highway map [HM] and two topographic maps, Charleston South [CS] and Rend Lake Dam [RLD] . You are currently located in Urbana, Illinois. Consulting your Illinois highway map, you find that the index coordinates for Urbana are _____ [1-HM] . The precise population of Urbana at the date of this map is ____ [2-HM] . Urbana is located in ____ county [3-HM] , and the symbol used for Urbana tells you that it is the _____ [4-HM] of this county. Exam Format
