Passage: Frank Chambers a drifter, stops at a depression-era rural California diner for a meal and ends up working there. The diner is operated by a young, beautiful woman, Cora Smith, and her much older husband, Nick Papadakis, a hardworking but unimaginative immigrant from Greece.
Frank and Cora start to have an affair soon after they meet. Cora is tired of her situation, married to an older man she does not love, and working at a diner that she wishes to own and improve. She and Frank scheme to murder Nick to start a new life together without her losing the diner. Their first attempt at the murder is a failure, but Nick is not even aware they tried to kill him, so goes about living his life as usual. Frank and Cora succeed with their next attempt.
The local prosecutor suspects what has actually occurred but does not have enough evidence to prove it. As a tactic intended to get Cora and Frank to turn on one another, he tries only Cora for the crime.
Although they turn against each other, a clever ploy from Cora's lawyer, Katz, prevents Cora's full confession from coming into the hands of the prosecutor. With the tactic having failed to generate any new evidence for the prosecution, Cora benefits from a deal in which she pleads guilty to manslaughter and is sentenced to probation.
Months later, Frank has an affair with Madge Gorland while Cora is out of town. When Cora returns, she tells Frank she is pregnant. That night, Katz's assistant, Kennedy, appears at their door and threatens to expose them unless they give him $10,000. Enraged, Frank beats Kennedy up and strong-arms him into giving up the evidence against them.
Question: What are the last names of the people who are planning to murder Nick?
Smith.

Passage: The Slaters of Wolverhampton are plagued with Mrs. Slater's chronic debilitating asthma and her cooking limited to what comes in canned goods that she can heat in boiling water. Mr. Alan Slater is sick with worry and has a cantankerous personality. Nigel longs for a life that is more than a succession of canned-food dinners made from what can be heated in boiling water. When dinner is burnt, the standard substitute of toast is always served. He loves toast, with the crunchy outside giving way to buttery softness inside. Despite her infrequent forays into cooking meals from scratch, his mother's attempts to improve her cooking change nothing before or after her death. His father continues in widowhood with the same cooking style and frequent dinners of toast. The experience brings Nigel to conclude that he is not liked. Nigel learns from a friend that the way in which he could attempt a better relationship with his father is to cook a meal for him.
His cooking efforts are thwarted by the new housekeeper, the married and "common" Mrs. Joan Potter, who seduces Alan with her apple pie and array of gourmet meals. The two start to spend time together: at one point, she exiting her council house through an upstairs window so as not to be found out by her husband. Without announcement, the Slaters move to the Herefordshire countryside along with Mrs. Potter. Nigel co-exists with her but never accepts her. She makes a competition of cooking when the teenaged Nigel's shows an emerging interest in developing his skills at school home economics class cookery lessons. Mrs. Potter's lemon meringue pie becomes Nigel's quest to learn the secret recipe.
Question: While Nigel's mom has asthma, what makes his dad ill?
worry.

Passage: One evening, after getting drunk at a bar, Mitch and Dave urinate in a park's fountain, and simultaneously wish that they had each other's lives.
The next morning, Mitch and Dave realize they have switched bodies. Mitch remembers the wish they made the night before and they drive back to the park, planning to urinate again in the fountain and wish for their original lives back, but find the fountain has been removed for restorations. Forced to wait a few days until the parks department can locate the fountain, Mitch and Dave agree to pretend to be each other for the day. When Mitch arrives at Dave's law firm office, he befriends Dave's attractive assistant, Sabrina McKay. However, Mitch's lack of professionalism and legal knowledge cause a big merger to fall through. Meanwhile, Dave arrives at Mitch's film shoot to discover that it is a lorno (light porno).
Tired of pretending to be Mitch, Dave has them go back to his house to tell his wife Jamie the truth, but Jamie does not believe him. Dave gives Mitch advice on how to behave professionally and Mitch sets Dave up on a date with Sabrina, who Mitch has had a crush on.
After speaking with his father, Mitch rededicates himself to doing everything Dave's life demands, from taking care of the kids and buying groceries to making decisions at the firm. On the night of her ballet recital, Cara, Dave's eldest child, is about to be pushed by another girl who has a habit of bullying her, but takes Mitch's advice and throws her to the floor, to which Mitch foul-mouthedly cheers. Cara tells Mitch that she loves him and Mitch says the same thing, but feels guilty for doing so immediately after. That night, Mitch and Jamie begin to have sex with each other, but Mitch angrily finds that his guilt will not allow him to become erect, and he admits that he is not cut out for the responsibilities of an adult. Jamie comforts him, and he discreetly rests his head on her breasts.
Question: Who is the father of the girl who takes ballet?
Dave.
