You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.

Question:  Callista is set in the mid-3rd century in the city of Sicca Veneria in the Roman province of Africa. It deals with the persecution of the Christians community under Emperor Decius.
The main character of the novel is Callista, a young and beautiful Greek girl, who has arrived from Greece some years previously with her brother Aristo; they work for Agellius's uncle Jucundus, carving statues of pagan gods. She is a gifted young woman, yet she is unhappy with her life.
Another main character is the troubled young Christian Agellius, who wants to marry Callista. He is torn between his faith and his brother (Juba), his stepmother Gurta, a pagan witch, and his pagan uncle Jucundus, who all want to bring him away from the Christian faith. Agellius soon meets the mysterious Christian priest Caecilius (later identified as St. Cyprian of Carthage), who becomes a father figure for him and strengthens his faith again.
After a terrible plague of locusts, popular rage against Christians breaks out and persecution starts once again. Agellius has to flee from the surroundings of Sicca Veneria. At the same time, Callista sees herself drawn more and more strongly to Christianity. When she is compelled to offer incense to the pagan gods, she has to make a dramatic choice, which finally leads her into the Catholic Church and then to martyrdom.

Answer: Who all want allegius to move away from christianity?


Question:  Banzai (Peter Weller) prepares to test his Jet Car, a modified Ford F-350 pickup truck powered by a jet engine and capable of exceeding the speed of sound. The car is also equipped with a secret device called an "oscillation overthruster", which Banzai and his associates hope will allow it to drive through solid matter. The test is a success: Banzai stuns onlookers by driving the Jet Car directly through a mountain. Emerging on the other side, Banzai finds that an alien organism has attached itself to the undercarriage.
Hearing of Banzai's success, physicist Dr. Emilio Lizardo (John Lithgow) breaks out of the Trenton Home for the Criminally Insane, after being held there for 50 years. A flashback shows Banzai's mentor, Dr. Hikita (Robert Ito), was present at Lizardo's failed overthruster experiment in 1938. Crashing half through the target wall, Lizardo had been briefly trapped in the 8th dimension where his mind was taken over by Lord John Whorfin.
Whorfin is the leader of the Red Lectroids, a race of alien reptiles who wage war against Planet 10. After being defeated by the less-aggressive Black Lectroids, Whorfin and his group were banished into the eighth dimension. Lizardo's failed experiment accidentally released Whorfin and he soon brings many of the Red Lectroids to Earth in an incident that was reported in 1938 by Orson Welles in his radio broadcast The War of the Worlds, only to be forced by the aliens to retract it all as fiction.
The Red Lectroids now pose as employees of the defense contracting company named Yoyodyne Propulsion Systems. They have been working on building a large spacecraft under the guise of a United States Air Force program, the Truncheon bomber. They intend to rescue the remaining 8th dimension exiles and take over Planet 10. They were unable to produce a working overthruster like Banzai's, so Whorfin plans to steal it. Banzai's team, the Hong Kong Cavaliers, finds out about Yoyodyne and hacks into their computer. They discover that everyone there has the first name John, with various last names such as Yaya, Smallberries and Bigboot . At first they believe it to be a joke, but then they notice all the Yoyodyne employees applied for Social Security cards on November 1, 1938 and all in the same town: Grover's Mill, New Jersey.
In the meantime, a Black Lectroid spacecraft orbiting Earth contacts Banzai, giving him an electric shock that enables him to see through Lectroids' camouflage. (Black Lectroids appear to be Rastafarian Jamaicans, while Red Lectroids appear to be Caucasians.) The ship also sends a "thermo-pod" to Earth, with a holographic message from the Black Lectroids' leader, John Emdall (Rosalind Cash), explaining Lord Whorfin's motives and giving an ultimatum: stop Whorfin and his army or else the Black Lectroids will protect themselves by staging a fake nuclear attack, causing the start of World War III.
With help from the Black Lectroid messenger John Parker, Banzai and the Hong Kong Cavaliers, a collection of civilian volunteers named "The Blue Blaze Irregulars" and a young woman named Penny Priddy (Ellen Barkin), a long-lost twin sister of Buckaroo's late wife, Buckaroo succeeds in his mission, destroying the Red Lectroids and saving Earth. The end credits announce an unproduced sequel Buckaroo Banzai Against the World Crime League.

Answer: What is the name of the secret device installed within the Jet Car?


Question:  Halsey's Planet is in decline, and when a generation ship arrives, having failed to contact six other planets, Ross is sent to discover the state of the interstellar colonies. He is given a ship which can make the trip from colony to colony almost instantaneously. The technology used in the ship has been kept secret because it could give rise to interstellar war if one colony decided to conquer others. However, the isolated populations are also affected by genetic drift resulting in a decline in their societies.
The first planet he visits has been completely destroyed, the second is a gerontocratic travesty of a democracy, and the third is a repressive matriarchy. On the way he picks up companions Helena and Bernie.
The next planet they visit is supposed to be Earth, but it turns out not to be; not only are its planetary statistics different from Earth's, but it is populated by a race of almost-identical people called Joneses. This planet, also called Jones, is ruled by a cult of total conformity in all areas of life, including genetic phenotype. Ross discovers that the equation whose meaning he has been seeking refers to the loss of unfixed genes in a small population, which explains the degeneracy of the planets he has visited. Dr. Sam Jones learns that he has been worshiping an equation on genetic drift, and joins the little band.
They sort out their navigational problem and finally make it to Earth, which is a civilisation of morons protected by a small minority of hidden geniuses, like the situation in "The Marching Morons". Ross realises that the problem with all the degenerate worlds is their isolation; luckily he has the FTL drive and so sets about rectifying the problem by bringing them together.

Answer:
What does the equation refer to ?
