Q: In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.
As the movie begins the viewer is introduced to Prico, a young Italian boy who lives with his parents in a middle-class household. His mother, Nina, takes him to a local park where he enjoys his time out while watching a puppet show, but is also concerned with a handsome lover named Roberto (with whom Nina has shared a past romance) courting his mother while he is assumed to not be paying attention. As the boy returns home, the family has dinner while Prico reflects on his day in the park. Later that night, after his mother puts him to bed, she runs off with the stranger, leaving Prico's father distressed at the idea of having to raise his son himself. While their neighbors share a number of rumors concerning the disappearance of Nina, it is quickly agreed that she ran off with another man. While concerned with her disappearance, Nina quickly returns to the home after a few days for the sake of their son. While the father, Andrea, is not entirely pleased with this arrangement, he relents so that his son may grow up in the same house as his mother.To distance herself from Roberto, Nina and Andrea agree to go on vacation with their son to a nearby beach hotel. The vacation occupies their time, seemingly happy with the prospect of a reunion. After Andrea says that he must go back home to his job, he suggests that Nina stay with Prico a few extra days that they may enjoy their time. After leaving, Nina is again pursued by Roberto who shows up unexpectedly at a hotel dance, at first successfully keeping him away. But after yielding to him once again, Prico is dismayed by her lack of faith. After Prico runs away, he is eventually brought back by the police officers while the hotel residents quickly start their own rumors as to the cause of his departing.After Prico and his mother return to their home town, Nina tells him outside their home to go on up and that she'll be up after going on an errand. When Prico goes to see his father upstairs, he and his father realize the truth of why Nina is not there. Again distressed at the elopement of his wife, Andrea enrolls Prico in a boarding school. While his son is away, Andrea kills himself in despair. When Prico is told of the death at the school, both his mother and faithful maid are there to comfort him. Though very young, Prico understands the nature of his mother, refusing to go to her for comfort in favor of his maid. The film ends with Prico walking off, refusing to acknowledge his mother.
