1. Correct Answer: c: 3 to 7
 2. Explanation:
     To solve this problem, we need to determine the minimum and maximum number of males who have a driver's license.
     Step 1: Understand the given data.
         ○ Total number of applications: 120
         ○ Number of males: 70
         ○ Number of applicants with a driver's license: 80
     Step 2: Determine the minimum number of males with a driver's license.
         ○ To find the minimum number of males with a driver's license, assume that the maximum number of females have a driver's license.
         ○ Total females = Total applications - Total males = 120 - 70 = 50
         ○ If all 50 females have a driver's license, then the minimum number of males with a driver's license = Total with driver's license - Females with driver's license = 80 - 50 = 30
     Step 3: Determine the maximum number of males with a driver's license.
         ○ To find the maximum number of males with a driver's license, assume that the minimum number of females have a driver's license.
         ○ If no females have a driver's license, then all 80 people with a driver's license are males.
         ○ Therefore, the maximum number of males with a driver's license = 80
     Step 4: Calculate the ratio.
         ○ Minimum number of males with a driver's license = 30
         ○ Maximum number of males with a driver's license = 70 (since there are only 70 males in total, the maximum cannot exceed this number)
         ○ Ratio of minimum to maximum = 30:70 = 3:7
     Therefore, the ratio between the minimum to maximum number of males having a driver's license is 3 to 7.
