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.
One example: Twenty-year-old Will Hunting of South Boston is a self-taught, genius-level intellect, though he works as a janitor at the Massachusetts Institute of Technology and spends his free time drinking with his friends, Chuckie (Ben Affleck), Billy (Cole Hauser) and Morgan (Casey Affleck). When Professor Gerald Lambeau (Stellan Skarsgard) posts a difficult mathematics problem as a challenge for his graduate students, Will solves the problem anonymously, stunning both the graduate students and Lambeau himself. As a challenge to the unknown genius, Lambeau posts an even more difficult problem. Lambeau chances upon Will solving the problem but Will flees the scene. That night at a bar, Will meets Skylar (Minnie Driver), a British student about to graduate from Harvard, who plans on attending medical school at Stanford and gives Will her phone number before leaving.
Solution is here: How old is Will Hunting in the movie ?

Now, solve this: In the city of Basra, the evil vizier Jaffar has clouded the caliph's mind and imprisoned his daughter, Princess Alina in order to marry her. Jaffar has four of the town's five sacred gems sent to dangerous and evil places where they will be carefully guarded by magical forces. Sinbad and his crew arrive at the caliph's palace, only to be captured by the hypnotised soldiers. Jaffar sentences Sinbad's crew to the torture chamber while the mighty sailor is to be locked in a pit full of snakes. Sinbad gets out of the snake pit using some snakes tied together into a rope and later rescues his companions from the torture chamber. As they flee the controlled Basra, Jaffar grants power from evil forces to help him kill Sinbad, this summons an evil cloud over Sinbad's ship and the Legions of Darkness, undead warriors. Together with the help of his friends, Sinbad manages to defeat the undead and the leader. Sinbad heads to a mysterious island to seek the help of a wise Oracle, who tells them the location of the four sacred gems of Basra. Then, he sails to an island and finds the gem by himself, he destroys a towering rock monster and retrieves the gem. Jaffar is joined by another ally, Soukra, a sorceress, and they prepare Jaffar's scheming plan. The second gem is on the island of the Amazons, the Amazons hypnotise Sinbad's crew and the Queen takes Sinbad with her. The Bald Cook and Poochie the dwarf save Sinbad and retrieves the second gem, the Queen's necklace. Next, Sinbad and his team head to the Isle of the Dead, where they battle Ghost Knights who have risen from the dead to fulfill their destiny. Sinbad goes for the Ghost King while his companions battle the Knights. Jaffar casts Sinbad's ship and his crew in the middle of the sea, leaving the sailor alone on the Isle of the Dead. Jaffar gives life to the Ghost King using his evil powers, and it weakens Sinbad, but he resists and destroys the Ghost King with his own sword and takes the third sacred gem. Later, Sinbad meets Kira, and her father, Nadir the wizard, two survivors on the Isle of the Dead who came there on a flying balloon. Sinbad agrees to help them get rid of the vicious monsters of the island and is aided by Kira, they encounter a group of ghouls, Sinbad fights them but Kira is captured by them. Sinbad rescues Kira but has to face a terrible monster able to fire bolts of energy from its wrists guarding the last sacred gem of Basra, Sinbad defeats the evil creature with the gems he has and retrieves the last one and they, along with Nadir escape the island on a balloon. Sinbad meets up with his companions and they go off to face Jaffar, Sinbad's men face off the soldiers while Sinbad battles Jaffar.
