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?The key statement is that highly successful entrepreneurs are
unique in always implementing solutions they see. So anyone who always implements such solutions must belong to that group. And all members of that group have
leaving a mark on the world as their main desire.
(A) 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.
Incorrect. We know other people value leisure time or job security enough not always to implement their ideas. We do not know whether they want to leave a mark on the world.
(B) All people who invariably implement their solutions to problems have at least some interest in leisure time or job security.
Incorrect. Nothing tells us that highly successful entrepreneurs must have any interest in leisure time or job security.
(C) The main desire of all people who implement solutions whenever they detect them is to leave a mark on the world.
Correct. Only highly successful entrepreneurs always implement the solutions they see. Therefore, anyone who does this is a highly successful entrepreneur. Since all highly successful entrepreneurs have leaving a mark on the world as their main desire, (C) must be true.
(D) Generally, highly successful entrepreneurs' interests in leisure time or job security are not strong enough to have a negative impact on their ability to see solutions to problems.
Incorrect. The passage discusses whether such interests reduce people's
motivation to implement solutions, not whether they affect their ability to see solutions.
(E) All people whose main desire is to implement their solutions to problems leave a mark on the world.
Incorrect. The passage does not discuss people whose main desire is implementing solutions, nor does it guarantee that anyone actually succeeds in leaving a mark on the world.
Answer: (C)
