In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: Jack and Sarah are expecting a baby together, but a complication during the birth leads to the death of Sarah. Jack, grief-stricken, goes on an alcoholic bender, leaving his daughter to be taken care of by his parents and Sarah's mother, until they decide to take drastic action: they return the baby to Jack whilst he is asleep, leaving him to take care of it. Although he struggles initially, he eventually begins to dote on the child and names her Sarah.
Despite this, he nevertheless finds it increasingly difficult to juggle bringing up the baby with his high-powered job, and though both sets of the child's grandparents lend a hand (along with William, a dried out ex-alcoholic who, once sober, proves to be a remarkably efficient babysitter and housekeeper), he needs more help. Amy, an American waitress he meets in a restaurant who takes a shine to Sarah, takes up the role as nanny, moving in with Jack after one meeting.
Although clashing with William and the grandparents, especially Jack's mother, Margaret, Jack and Amy gradually grow closer—but Jack's boss has also taken an interest in him.
[A]: Who finds it hard to raise the baby and do his job?


[Q]: Passage: The CIA is secretly developing "Crossbow", a space shuttle-mounted laser weapon precise enough to incinerate a single target from outer space, planning to use it for illegal political assassinations. However, they struggle with its power source, and have covertly hired Professor Jerry Hathaway at Pacific Technical University to develop this. Hathaway has assembled a group of genius students in physics to do the work for him, though outside of his graduate student Kent, purposely does not tell them the reason for their research. Hathaway is also embezzling the CIA provided funds intended for research so that he can upgrade his house.
Hathaway recruits high-school student Mitch Taylor to join the team. Mitch is roomed with Chris Knight, a "legend" in the physics area. Mitch becomes dismayed that Chris is more of a goof-off than a hard-working student. Chris introduces Mitch to some of the other genius students, including Jordan, "Ick" Ikagami, and his nemesis, the less intelligent Kent. Despite his age and inexperience, Hathaway assigns Mitch to lead the team due to his fresh and inventive ideas, hoping that he will remind Chris of how he used to be.
[A]: What is the man who hired the genius students helping to develop?


[Q]: Passage: Bach is known as a prolific composer of cantatas. When he assumed the position as Thomaskantor (director of church music) in Leipzig in 1723, he began the project to write church cantatas for the occasions of the liturgical year – Sundays and feast days – a project that he pursued for three years.Bach was appointed organist and chamber musician in Weimar at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August on 25 June 1708. He had composed sacred cantatas before, some during his tenure in Mühlhausen from 1706 to 1708. Most were written for special occasions and were based mainly on biblical texts and hymns. Examples include: Aus der Tiefen rufe ich, Herr, zu dir, BWV 131; the early chorale cantata Christ lag in Todes Banden, BWV 4 for Easter; Gott ist mein König, BWV 71, to celebrate the inauguration of the new city council on 4 February 1708; and the Actus Tragicus for a funeral.
In Weimar, Bach first concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. Christoph Wolff suggests that Bach may have studied musical material belonging to the Hofkapelle, ("court capelle" or court orchestra), and that he copied and studied works by Johann Philipp Krieger, Christoph Graupner, Georg Philipp Telemann, Marco Giuseppe Peranda and Johann David Heinichen in the period from 1711 to 1713. In early 1713 Bach composed his first cantatas in the new style that included recitatives and arias: the so-called Hunting Cantata, BWV 208, as a homage cantata for Christian, Duke of Saxe-Weissenfels, celebrated on 23 February, and possibly the church cantata for Sexagesima (the second Sunday before Lent) Gleichwie der Regen und Schnee vom Himmel fällt, BWV 18, on a text by Erdmann Neumeister.In 1713, he was asked to apply for the position of music director of the Marktkirche in Halle, succeeding Friedrich Wilhelm Zachow. Zachow had taught the young George Frideric Handel, and  composed many church cantatas in the new style, adopting recitatives and arias from the Italian opera. Bach was successful in his application for the position, but declined after Duke Wilhelm Ernst increased his salary and offered him a promotion.
