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. 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. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is 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.
1990s LA police detective Mike Church took the case of amnesia-suffering mute client' Grace; she was having nightmares about the murder of a pianist named Margaret Strauss by her world-famous composer/conductor husband Roman Strauss in the late 1940s; Margaret had been suspicious that Roman's housekeeper Inga and her disturbed, stammering son Frankie were stealing her husband things; Roman was falsely put to death by electric chair for the murder of his wife Margaret, who was actually stabbed and murdered with a pair of scissors by Frankie, because his mother was in love with Roman; in the present day story, Mike came into contact with hypnotist/antique dealer Franklyn Madson who believed that Grace had suffered trauma in her past life; under regressive hypnosis, it was revealed that there were remarkable similarities and parallels between the stories of Roman and Margaret in the past, and Mike and Grace in the present; it was discovered that Mike was the reincarnation of murdered pianist wife, Margaret; and amnesia-suffering Grace was the reincarnation of executed composer Roman Strauss; the hypnotist (the murderer from the 40s) died when impaled on a large scissor sculpture made by 'Grace' and Mike held his partner 'Grace'.
