In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Passage: Chris Emerson, a young former surfing pro and his younger sister Nicole move to Luna Bay, California, following the death of their parents, to live in a house owned by their aunt Jillian. Chris leaves his address at the home of Edgar Frog, the town's surfboard shaper, in hopes of getting a job. Chris is approached at their new home by former pro surfer, Shane Powers (played by Angus Sutherland the half brother of Kiefer Sutherland who played David from the original film), who invites him to a party that night.
Chris and Nicole go to the party, where Shane and his friends Kyle, Erik and Jon are entertaining themselves with the human guests. Chris showers with a girl named Lisa and Shane gets Nicole alone, chats with her for a bit, and then tricks her into drinking his blood. When Chris learns that Nicole has been with Shane, he angrily, and protectively, takes her home, where she begins to manifest vampiric strength and rage. But before Nicole kills Chris, she is knocked out by Edgar, who reveals that he is a vampire hunter, and Nicole has been infected with vampirism. Chris throws Edgar out of the house. Then, Lisa shows up and pretends to chat with Chris for a bit before she finally tries to seduce and feed on him. In fending her off, he accidentally impales her on a mounted rack of antlers, killing her explosively when she turns into stone and explodes.
Finally convinced of the situation, remembering what Edgar said and believing that he was right, Chris seeks out Edgar's help. Edgar explains that Nicole is only half-vampire, and will remain that way unless she feeds, and she can be turned human again if they kill the head vampire before that. Chris interrupts her just before she can feed on Evan Monroe, a nice guy who has been courting her, and explains what is happening to her, and Nicole is surprised at what she almost did (because she believes herself to be a vegetarian). However, Shane draws her to their lair and they have sex.
Question: What is the name of the person that starts to manifest vampire strength?
Nicole.

Passage: Bach's early cantatas are Choralkonzerte (chorale concertos) in the style of the 17th century, different from the recitative and aria cantata format associated with Neumeister that Bach started to use for church cantatas in 1714. Wolff points out the relation of Bach's early cantatas to works by Dieterich Buxtehude, with whom Bach had studied in Lubeck. Christ lag in Todes Banden shows similarities to a composition of Johann Pachelbel based on the same Easter chorale. Although there is no evidence that Bach and Pachelbel met, Bach grew up in Thuringia while Pachelbel was based in the same region, and Bach's elder brother and teacher Johann Christoph Bach studied with Pachelbel in Erfurt. Another of Pachelbel's works appears to be referenced in the early Bach cantata, Nach dir, Herr, verlanget mich, BWV 150, and there has been recent speculation that Bach wanted to pay tribute to Pachelbel after his death in 1706.The texts for the early cantatas were drawn mostly from biblical passages and hymns. Features characteristic of his later cantatas, such as recitatives and arias on contemporary poetry, were not yet present, although Bach may have heard them in oratorios by Buxtehude, or even earlier. Instead, these early cantatas include 17th-century elements such as motets and chorale concertos. They often begin with an instrumental sinfonia or sonata (sonatina). The following table lists the seven extant works composed by Bach until 1708, when he moved on to the Weimar court.
Bach uses the limited types of instruments at his disposal for unusual combinations, such as two recorders and two viole da gamba in the funeral cantata Gottes Zeit ist die allerbeste Zeit, also known as Actus Tragicus. He uses instruments of the continuo group as independent parts, such as a cello in Nach dir, Herr, verlanget mich and a bassoon in Der Herr denket an uns. The cantata for the inauguration of a town council is richly scored for trumpets, woodwinds and strings. Wolff notes:
The overall degree of mastery by which these early pieces compare favourably with the best church compositions from the first decade of the eighteenth century ... proves that the young Bach did not confine himself to playing organ and clavier, but, animated by his Buxtehude visit, devoted considerable time and effort to vocal composition. The very few such early works that exist, each a masterpiece in its own right, must constitute a remnant only ... of a larger body of similar compositions.
The Bach scholar Richard D. P. Jones notes in The Creative Development of Johann Sebastian Bach:
"His remarkable flair for text illustration is evident even in the early cantatas, particularly the two finest of them, the Actus tragicus, BWV 106, and Christ lag in Todes Banden, BWV 4. We already sense a powerful mind behind the notes in the motivic unity of the early cantatas, in the use of reprise to bind their mosaic forms together ...".
Question: What often begin with an instrumental sinfonia or sonata?
cantatas.

Passage: The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District; Manhattan gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (about $23 billion in 2018 dollars). Over 90% of the cost was for building factories and to produce fissile material, with less than 10% for development and production of the weapons. Research and production took place at more than 30 sites across the United States, the United Kingdom, and Canada.
Two types of atomic bombs were developed concurrently during the war: a relatively simple gun-type fission weapon and a more complex implosion-type nuclear weapon. The Thin Man gun-type design proved impractical to use with plutonium, and therefore a simpler gun-type called Little Boy was developed that used uranium-235, an isotope that makes up only 0.7 percent of natural uranium. Chemically identical to the most common isotope, uranium-238, and with almost the same mass, it proved difficult to separate the two. Three methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this work was performed at the Clinton Engineer Works at Oak Ridge, Tennessee.
In parallel with the work on uranium was an effort to produce plutonium. After the feasibility of the world's first artificial nuclear reactor was demonstrated in Chicago at the Metallurgical Laboratory, it designed the X-10 Graphite Reactor at Oak Ridge and the production reactors in Hanford, Washington, in which uranium was irradiated and transmuted into plutonium. The plutonium was then chemically separated from the uranium, using the bismuth phosphate process. The Fat Man plutonium implosion-type weapon was developed in a concerted design and development effort by the Los Alamos Laboratory.
The project was also charged with gathering intelligence on the German nuclear weapon project. Through Operation Alsos, Manhattan Project personnel served in Europe, sometimes behind enemy lines, where they gathered nuclear materials and documents, and rounded up German scientists. Despite the Manhattan Project's tight security, Soviet atomic spies successfully penetrated the program.
Question: What isotope had almost the same mass as uranium-238?
uranium-235.
