Question: Passage: In March 1943, DuPont began construction of a plutonium plant on a 112-acre (0.5 km2) site at Oak Ridge. Intended as a pilot plant for the larger production facilities at Hanford, it included the air-cooled X-10 Graphite Reactor, a chemical separation plant, and support facilities. Because of the subsequent decision to construct water-cooled reactors at Hanford, only the chemical separation plant operated as a true pilot. The X-10 Graphite Reactor consisted of a huge block of graphite, 24 feet (7.3 m) long on each side, weighing around 1,500 short tons (1,400 t), surrounded by 7 feet (2.1 m) of high-density concrete as a radiation shield.The greatest difficulty was encountered with the uranium slugs produced by Mallinckrodt and Metal Hydrides. These somehow had to be coated in aluminum to avoid corrosion and the escape of fission products into the cooling system. The Grasselli Chemical Company attempted to develop a hot dipping process without success. Meanwhile, Alcoa tried canning. A new process for flux-less welding was developed, and 97% of the cans passed a standard vacuum test, but high temperature tests indicated a failure rate of more than 50%. Nonetheless, production began in June 1943. The Metallurgical Laboratory eventually developed an improved welding technique with the help of General Electric, which was incorporated into the production process in October 1943.Watched by Fermi and Compton, the X-10 Graphite Reactor went critical on 4 November 1943 with about 30 short tons (27 t) of uranium. A week later the load was increased to 36 short tons (33 t), raising its power generation to 500 kW, and by the end of the month the first 500 mg of plutonium was created. Modifications over time raised the power to 4,000 kW in July 1944. X-10 operated as a production plant until January 1945, when it was turned over to research activities. 
Question: Where was DuPont planning to build a larger plant?

Answer: Hanford.


Question: Passage: In 1943, in preparation for overseas deployment, 400 pilots and 3,600 crewmen of the 351st Bombardment Group assemble at a Colorado air base. Arriving in England, as part of the Eighth Air Force, the 351st BG is welcomed by the Royal Air Force and begins training, attending daily lectures on security. Their first mission flying Boeing B-17 Flying Fortress bombers has the armada departing at 15-second intervals.
The first mission of the 351st on Fortress Europe, after fighting through Luftwaffe defenders, is a success, with all 20 B-17s returning safely back to base. The danger of flying in massed formation, however, is brought home in training, when a collision takes place over the home base. Missions are also not always without casualties and 351st bombers are shot down.  Wounded airmen who make it back to base, are cared for at a nearby hospital. When bombers are all shot up, the ground crew works up to 90-hour periods to put them back into service.
As the mission tallies build, the men partake in activities at the base, including games, socializing and worship. The U.S.O. brings entertainers such as Bob Hope while the Red Cross provides the men with rest and recreation. During special parades, commanders of the 8th Air Force bestow medals for exceptional service and sacrifice.
The 351st participates in a big mission into Germany and after flying for about three hours, the B-17s' fighter escort turns back. As the bombers near their target to drop incendiary and anti-personnel bombs, enemy fighter aircraft appear and intense flak comes up from the ground. After a long battle, the 351st returns to base, ready to fight again until the war is over. 
Question: What is the formal name for the armada?

Answer: 351st Bombardment Group.


Question: 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: Who does Chis Emerson impale with a mounted rack of antlers?

Answer:
Lisa.
