There has been a quiz running on this blog with the question: What is the name of the current Pope of the Catholic Church?. Find the current standing of answers in the figure to the right.
It’s good to see a lot of different answers and indeed, a problem with the quiz is that all answers may be correct. While Francis is the name as pope in English chosen by Jorge Mario Bergoglio, the pope has other names in other languages as Frans in Danish and Norwegian, François in French, Franziskus in German and Francesco in Italian.
