Ann will either take a leave of absence from Technocomp and return in a year or else she will quit her job there; but she would not do either one unless she were offered a one-year teaching fellowship at a prestigious university. Technocomp will allow her to take a leave of absence if it does not find out that she has been offered the fellowship, but not otherwise. Ttherefore, Ann will quit her job at Technocomp only if Technocomp finds out she has been offered the fellowship.
Ann would be offered the fellowship only if she quit her job at Technocomp allows the conclusion above to be properly drawn.
