perhaps italian prime minister matteo renzi has learned a thing or two watching the trend and he promised to resign if a referendum to reform the constitution has failed but he has recently backed down from that pledge. the lesson here is clear, in today's climate if you give people a chance to register a protest with their votes, they will. the correct answer to the gps challenge question is c., north america. there have been no secretaries general from north america, australia or antarctica. the eight secretaries general so far have all hailed from europe, asia, africa or south america and they have all been men. while there were women in the running to be ninth secretary general, the top three candidates in the security council vote were all men and the council eventually chose former portuguese prime minister and u.n. high commissioner for refugees antonio guiterrez. thank you for being part of my program for this week.
