Question: Passage: When two grade-school boys get into a fight in the park that results in one boy, Zachary Cowan, hitting the other, Ethan Longstreet, in the face with a stick, their parents meet in a Brooklyn apartment to discuss the matter. Zachary's parents, Alan and Nancy Cowan, visit the home of Michael and Penelope Longstreet, Ethan's parents. Their meeting is initially intended to be short, but due to various circumstances, the conversation continues to draw out.
In fact, Alan and Nancy begin to leave the apartment on two occasions, but are drawn back in to further discussion.
At first, the couples are friendly to each other, but their respective comments start to hurt feelings, making everyone argue with one another. Apart from fighting among themselves, the couples blame each other about who is responsible for the fight between their sons. Nancy calls the Longstreets "superficially fair-minded" and Penelope and Michael complain about Alan's arrogant and dull attitude. Everyone also gets irritated with Alan when he accepts endless business phone calls on his BlackBerry, interrupting the discussion, and showing he has more interest in his business problems than the matter at hand. Michael also receives many phone calls from his ailing mother, to his frustration.
Nancy accuses Michael of being a murderer because he, annoyed by the constant noise it made during the night, had earlier turned his daughter Courtney's pet hamster loose in the street. Penelope becomes emotional about the hamster and with everyone arguing with each other. Other issues include a risky drug Alan is working to defend and Michael's mother has been prescribed, and the question of idealism and responsibility that is part of Penelope's current work.
Question: Who is Courtney's father?

Answer: Michael.

Question: Passage: Following the Seven Years' War (175663) and the forced migration of Native American tribes westward, German, Scots-Irish, and other European immigrants settled in the central Susquehanna Valley, including in the area that would become Northumberland, Pennsylvania. Northumberland was laid out around a central village green in 1772, on land originally purchased from the Iroquois by the Province of Pennsylvania in 1768, as part of the first Treaty of Fort Stanwix. During the American Revolution, the village was evacuated as part of the Big Runaway in 1778, and only finally resettled in 1784. In 1794, when the Priestleys moved there, it included Quaker and Wesleyan meeting houses, a brewery, two potteries, a potash manufacturer, a clock maker, a printer (who issued a weekly newspaper), several stores, and approximately one hundred houses.
The Priestley property, purchased in 1794 at a total cost of 500 ( 56,400 in 2019) from Reuben Haines, who had secured the patent to the land for Northumberland, comprised four lots of the original village plan (numbers 2932). Currently, the house and grounds occupy 1 acre (4,000 m) at 472 Priestley Avenue. (The address of the house was originally "North Way", but the street was later renamed in honor of Joseph Priestley.) This street forms the northwest boundary of the property; the other boundaries are Hanover Avenue to the northeast, Wallis Street to the southwest, and the North Shore Railroad to the southeast. Beyond the railroad line is a baseball field, and beyond that lies the Susquehanna River, which was the original southeastern boundary of the property. The confluence of the West Branch Susquehanna River with the main (or North) branch of the Susquehanna is a short distance southwest of the property, which is at an elevation of 456 feet (139 m).The property's original area was 2 acres (8,000 m), but this was reduced by about half around 1830 when the Pennsylvania Canal (North Branch Division) was dug through the house's front yard, between the house and river. On May 31, 1860, the Lackawanna and Bloomsburg Railroad opened with a train from Danville. This was the second railroad track in Northumberland, and ran behind the house. The canal closed in 1902 and was later filled in. The modern railroad line approximates the canal's course through the front yard; the track behind the house no longer exists.
Question: What was reduced from 2 acres to 1 when the Pennsylvania Canal was dug?

Answer: The Priestley property.

Question: Passage: In 1935 England, Briony Tallis is a 13-year-old from a wealthy family. She has just completed writing her first play to mark her brother's homecoming and plans to stage it later that day with her visiting cousins.
Looking out of her bedroom window, she spies on her older sister, Cecilia, and the housekeeper's son, Robbie Turner, on whom Briony has a crush. Cecilia is undressing and dips into the fountain pool; a moment later, she climbs out, her undergarments wet, all while Robbie watches. Cecilia had gone to the pond to fill a vase, Robbie grabbed one of the handles, and it broke. A part fell into the pond, and Cecilia jumped in to retrieve it, but to Briony, it looked as if Robbie had ordered Cecilia to undress and go under the water.
Robbie drafts a series of notes to Cecilia apologizing for the incident, namely breaking the vase and laughing about it. One contains an explicit expression of his sexual desire for her, including frequent and crude usage of the word "cunt": he writes it only as a joke, and it makes him laugh to himself. He writes another, more formal letter, and asks Briony to deliver it. Only after she has gone does he realise he has given her the explicit letter.
Briony reads the letter before giving it to Cecilia. Later, she describes it to her older visiting cousin, Lola, who calls Robbie a "sex maniac". Paul Marshall, a visiting friend of Briony's older brother's and a chocolate magnate, introduces himself to the visiting cousins and appears to be attracted to Lola.
Before dinner, Robbie apologises for the obscene letter, but Cecilia surprises him and confesses her secret love for him. They then proceed to make passionate love in the library when Briony walks in, and thinks that Cecilia is under attack. Cecilia and Robbie try to pass the incident off.
Question: What is the full name of the person whose joke makes them laugh to them self?

Answer:
Robbie Turner.
