Inventor: All highly successful entrepreneurs have as their main desire the wish to leave a mark on the world. Highly successful entrepreneurs are unique in that whenever they see a solution to a problem, they implement that idea. All other people see solutions to problems but are too interested in leisure time or job security to always have the motivation to implement their ideas. If the inventor's statements are true, which one of the following must also be true? ['All people who invariably implement their solutions to problems have at least some interest in leisure time or job security.', 'All people whose main desire is to implement their solutions to problems leave a mark on the world.', 'The main desire of all people who implement solutions whenever they detect them is to leave a mark on the world .', 'Most people do not want to leave a mark on the world because trying to do so would reduce their leisure time or job security.']
