[Q]: Passage: vista pacific airlines Flight 7500 a boeing 747-300 departs from Los Angeles to Tokyo. Passengers on board include a group of two vacationing couples, Lyn and Jack and Brad and Pia, who have secretly broken up; a thief named Jake; a suspicious businessman traveling with a strange wooden box, Lance; a young woman named Raquel; newlyweds Rick and the snobby Liz; and the goth Jacinta. Air hostesses Laura and Suzy welcome the passengers on board, and Suzy questions Laura about her secret relationship with the married captain, Pete.
A few hours into the flight, the plane hits turbulence that soon passes.
Lance has a panic attack and begins to bleed profusely from his mouth. When Lance suddenly dies, Captain Pete continues to Japan, moving the first-class passengers into economy and keeping Lance's body in the closed-off first class.
Laura notices plastic water bottles collapsing and quickly warns everyone to fasten their seatbelts, just as the cabin pressure drops. As the oxygen masks are dispensed above the seats, a thick smoke fills the cabin. After the cabin pressure returns to normal and the smoke disappears, Laura finds Raquel unconscious in the toilet and revives her with an oxygen tank. Meanwhile, the plane's radio has stopped working and Captain Pete cannot contact Tokyo air traffic controllers.
Question: Who helps the young woman regain consciousness?
[A]: Laura.

[Q]: Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Peten lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles).
Question: Who had four iron and two bronze pedreros?
[A]: the Spanish.

[Q]: Passage: It is Halloween in the small town of Pitchford Cove located somewhere in New England, and five high school friends, Phil, Mary, Mitch, Vinnie, and Melissa, plan on making it a night they will never forget. They steal outfits from the town's historic museum and come upon other old artifacts, including an old trunk encasing a paper scroll which contains an ancient curse. When Melissa, latent sorceress, recites the curse at the local cemetery, things take a turn for the worse.
The town's dead, led by Melissa's great-great-great-great-grandmother Lucinda Cavender, a witch who was put to death 300 years earlier, rise up from their graves and roam the town. As Melissa, Vinnie, Mitch, and Mary enjoy themselves at their annual Halloween costume party, Phil encounters a mysterious girl, named Sandra "Sandy" Matthews, dressed in a vintage 1950's cheerleader outfit, who warns him that the whole town is in danger.
Meanwhile, Lucinda and the various undead crash the costume party. At first, nobody pays much attention to them since everyone is in costume. However, Lucinda begins turning the party guests into vampires, starting with her great-great-great-great-granddaughter Melissa.
When Sandy discovers that Phil and his friends recited the ancient spell in the cemetery, they realize that the whole town is being overrun by the living dead and decide to team up to break the curse. The only way to do so is to find the Grenville Spirit Ring inside the grave of a witch-hunter Nathaniel Grenville - who, coincidentally, was Phil's great-great-great-great-grandfather and slave owner of Lucinda Cavender, her arch-nemesis - and use it to undo the curse. Phil and "good ghost" Sandy must restore the town to normal by midnight before it is too late and the curse becomes permanent.
Question: What is the last name of the person who starts turning party guests into vampires?
[A]:
Cavender.
