Problem: Given the question: Question: Are the two surrounded by people or isolated? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Mother and Son Context: The film opens on two human forms, which soon reveal themselves to be that of a young man and a frail old woman. They recline in a silence broken only by whispers and indistinguishable noises. The young man is the son (Alexei Ananishnov) who is taking care of his exhausted sick mother (Gudrun Geyer). Her illness is undefined and from time to time causes her great pain as she gasps for air. Her son combs her hair, feeds her, covers her with a coat, and takes her in his arms. She is totally dependent on him as he himself was once totally dependent on her. As the film progresses, the son carries his mother on a long journey from her sickbed to her deathbed. It is a circular motion which travels a long walk through a dreamlike landscape in the countryside, along winding dirt roads. At each of their brief stops on the journey is a moment of contemplation, caresses, and tender murmurs. These soft murmurs tell of the mother's love for her son when she was nurturing him and of the son's love for his mother as he opens for her the mysterious path to her death. They progress under the leaden and luminous sky of the Baltic, in totally isolated landscapes. From time to time, there is a far away train or a sail on the sea, emphasizing further their isolation from the rest of the world. They return to the house. The son tenderly lowers his mother into her bed that now seems to resemble a coffin. Although he tries to reassure her to the contrary they both know that the end is coming. He leaves her and goes for a long solitary walk. When he returns he weeps for his mother who's died.

Problem: Given the question: Question: who finds a notebook in Robert's desk? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Proof Context: The plot alternates between events immediately following the death of Robert (Anthony Hopkins), a brilliant mathematician whose genius was undone by crippling mental illness, and flashbacks revealing the life he shared with his daughter Catherine (Gwyneth Paltrow). Catherine is also a mathematician, but she struggles with living in her father's shadow, with balancing her demanding studies with caring for her father and also with the fear that she may have inherited his mental illness. At home, Robert clings to sanity by constantly bombarding Catherine with complex mathematical problems. In the opening scene Robert startles Catherine while she watches TV in the middle of the night. He gives her a bottle of champagne for her birthday, and they chat for a while about the nature of insanity, ending with the revelation that Robert died last week and his funeral is tomorrow. Awakened from this dream, Catherine realizes that Hal (Jake Gyllenhaal), a former graduate student of Robert's, is still upstairs, reading through Robert's books. Robert filled many notebooks with meaningless notes. Hal believes that Robert's genius may have withstood his illness, and clues to that genius might lie among the gibberish of his notebooks. When Hal comments on the vast amount of work Robert did, a suspicious Catherine searches Hal's backpack. Though Catherine finds nothing in Hal's bag, a notebook falls out of his coat. He explains that he wanted to give the notebook as a birthday present because it "had something written in it about her, not math, her". Hal is forced to leave, giving the notebook as intended, when Catherine calls the police. The next day, for the funeral, Catherine's sister Claire (Hope Davis) arrives in town. A huge contrast to the unkempt Catherine, Claire is an overly put together, neurotic New Yorker. Relations between the sisters are tense, and Catherine cannot stand her sister's constant harping on matters of appearance. Catherine is also upset that Claire didn't care for her father as much as Catherine did...
