Han applies option c- he is challenging the credibility of sources. Ramona ,surprised, asks him if the evidence from Pettit's book was from fictional sources. Hans supports his claim through a review of Giovanni Fiorini's book. The material from this book which had been written by a story-teller and not by a historian was used by Pettit.
Option a- is wrong. Hans is not determining new research goals. He is questioning the credibility of sources.
Option b-is wrong. Hans is evaluating what an author said about Giovanni Fiorini's book. The material from this 'great' source was used by Pettit in <em>his </em>book.
Option d is wrong. Ramona is asking clarifying questions. She wants Hans to justify his claim. This states that the credibility of sources can be questioned.
I would say Anagnorisis. This means when a character makes a critical discovery, in this case he finds out he was sleeping with his mom and killed his father. It also means a change in what a person stood for. He stood for finding who was the killer, and cursed him, only to find out its him.
First I need to say that the common multiple is when two or more numbers meet up at the same point like 5 and 3 meeting up at 15. The common denominator works almost exactly the same way. It involve two fractions' denominators meeting up like 1/5 and 1/3 meeting up at ?/15 with ? being what the numerator would be (like 1/5 becoming 3/15 because 5 x 3= 15 and you must do so to the numerator so 1 x 3=3. 3/15). So they are alike in the way that they both involve two or more numbers' multiples meeting up, and the common multiple is basically used to find the common denominator.
