The correct answers are: “He is rather self-righteous” and “He considers himself to be a role model to others”. Taken from the “<em>The Tenth Story</em>” within the book “<em>The Decameron</em>” by Giovanni Boccaccio (1353), the speech presented in the excerpt above narrates the moment when Gualtieri explains the purpose of his tormenting Griselda all the previous years. Gualtieri reveals that he did all that in order to show her “<em>how to be a wife</em>” and to teach people “<em>how to choose a keep a wife</em>”, since <u>he considered himself to be </u><u>a role model</u>. The speech also describes Gualtieri’s personality, since he was too proud of his own moral behaviour and beliefs, in a way that annoyed other people. In fact, it is mentioned in the excerpt above that people despised his behaviour (“<em>and for those who considered me a cruel and bestial tyrant</em>”). This is why <u>one could describe him as </u><u>a self-righteous person</u>.

But has the desire to discover new worlds.
