Answer:
4. neither Inez nor Jock.
Step-by-step explanation:
Hi-Flite Corporation requires its drivers to have 20/20 vision without glasses. This vision is required by the company because the corporation believes that a 20/20 vision without glasses is necessary to maintain the safety of its pilots and others involved in the company's activities. This is a minimum requirement, so we can conclude that the Americans with Disabilities Act is not available in either Inez or Jock, as both cannot meet the company's minimum requirement.
