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.
Q: In Romania, theology student Allison has come into possession of The Lexicon, a mysterious book of prophecies that writes itself. This book contains a 23rd chapter of the book of Revelation, which is still not complete. The last chapter depicts the end of the war of angels and the name of the Antichrist. One of the angels who fell with Satan, Belial (now a demon), wants this book. Simon, a good angel, opposes him and guides Allison by taking advantage of her mental illness to speak directly to her. While searching for Allison and the book, and to avoid detection, Belial murders people and takes their form.Satan, pretending to be Interpol agent John Riegert, seeks the help of Dani Simionescu, a cop who, as a child, provided information to the Romanian secret police about his parents. His parents and baby sister were brought to one of the secret police headquarters and tortured. His baby sister gets hurt and is given up for adoption. Satan, as Riegert, reveals that she is Allison. During the investigation, Riegert uses Dani to help track Belial and locate his sister. After the police arrest Belial's current host, Belial possesses one of Dani's coworkers, Laurel.After revealing himself, Satan brings Dani to the house that was the site of the inhumane tortures. Allison, with guidance of the voices in her head, reaches the same place, followed by Belial, as Laurel. It is the only place where Belial cannot hurt Allison. It is a place of evil, which makes it Satan's domain, and he offers Allison his protection. Satan explains that, for his own motives, he is willing to assist humanity, as he does not wish Belial to succeed, though he is unable or unwilling to take direct action.Dani confesses his sins and seeks forgiveness but is rebuked by his sister. It is here that real motives are revealed. Belial, who was once loyal to Satan, has grown tired of the war between angels and its blurring of morality. Even Satan has taken more of shade of gray, and Belial wants to return to the black and white morality of earlier times. Satan opposes him because he wants to prolong the fighting and prevent a new Hell from emerging. Dani, realizing that Belial needs a host, shoots Laurel, but, before he can kill himself, he is possessed. Allison kills her brother, and Satan absorbs Belial's soul. After Allison forgives her brother, she leaves the house.At dawn, Satan tells Allison that, for the present, the war of angels is over, but it will not be for long. Showing her glimpses of her future, he advises her to keep the book safe.
