question:
Passage: In 1933, a child orphaned during the Ukrainian Holodomor runs away from his orphanage and is taken in by a Red Army unit and adopted by its kindly commander, who gives him the name Leo Demidov. In 1945, now a sergeant with the unit, Leo  becomes an icon across the Soviet Union when he is photographed planting the Soviet flag atop the Reichstag during the Battle of Berlin. He becomes a Hero of the Soviet Union.
In 1953, Leo, now married to Raisa and living in Moscow, is a captain in the Ministry of State Security, commanding a unit tasked with tracking down and arresting dissidents. They arrest a veterinarian, Anatoly Brodsky, and during the arrest, one of Leo's subordinates, the cowardly but ambitious Vasili Nikitin, shoots a farmer, Semyon Okun, and his wife in whose barn Brodsky has been hiding, orphaning their two young daughters. Angry, Leo strikes Vasili, who harbours growing resentment against Leo and the other officer in the unit, Alexei Andreyev; all three were in Berlin together in 1945. Vasili is in charge of Brodsky's interrogation and execution, and one of the names he gives to their superior, Major Kuzmin, is that of Raisa, a primary school teacher, several of whose colleagues have recently been arrested for dissident views. Kuzmin orders Leo to investigate his own wife.
Meanwhile, Alexei's young son, Jora, is found dead near a railway yard. Although the initial pathology report shows injuries consistent with torture, the surgically precise removal of organs, and drowning, the authorities declare that he was hit by a train, as Stalin has decreed that murder is a capitalist disease; there is no murder in a communist paradise. Alexei is forced to accept the official conclusions to save himself and the rest of his family. 
Question: What is the profession of the man that the person in Leo's unit interrogates?
answer:
veterinarian.

Passage: Inhabited on a mysterious island are strange creatures called Boggs who love meat. Unbeknownst to them, it is also inhabited by a shipwrecked boy. He scavenges for some food by distracting the Boggs with animal noises. Far away from the island, Odette and Derek are on their way to help the people by building a bridge leaving Alise in the care of Queen Uberta, Lord Rodgers, and their animals friends: Speed, Jean-Bob, Puffin and the Scullions. Queen Uberta begins to prepare Alise to learn how to be and act like a princess. But Alise doesn't want to be a princess in this way but to be a modern princess. Lord Rogers says that Alise needs adventure but Queen Uberta disagrees.
While fighting once again, Alise uses her chance to swim in the lake with her friends but she was quickly sent back to the palace to learn to be proper. Queen Uberta is very strict with Alise, trying to teach her everything, but instead she falls asleep and sent to bed. That same night, Lord Rogers, Jean-Bob, and Speed sneak Alise out of her room to go on an adventure.
The next morning, before Queen Uberta enters Alise's room with yoga lessons, she notices that Alise has gone with Lord Rogers. Queen Uberta chases after the group all the way to the port but they escape on a ship. Queen Uberta is furious but nervous about Alise so she sent Puffin and the Scullions after them.
On the ship, Alise changes into a pirate costume, making Lord Rogers realize that Uberta was right; he turned Alise into a pirate just when Alise wanted to have fun. On the first night they see the Polar Star and Lord Rogers says that sailors always used this star to guide the way back home. 
Question: Who all does the queen chase all the way to the port?
answer:
Lord Rogers.


question:
Passage: Returning from a Hong Kong business trip, Beth Emhoff has a layover in Chicago to rendezvous with a former lover before returning to her family in Minneapolis. She appears to have contracted a cold during her trip. Her six-year-old son from a previous marriage, Clark, also becomes sick and is sent home from school. Beth's condition worsens and two days later she collapses with severe seizures. Her husband, Mitch, rushes her to the hospital, but she dies of an unknown cause.
Mitch returns home and finds that Clark has also died from a similar infection. Mitch is placed in isolation, but seems to be immune to the disease. He is released and returns home to his teenage daughter Jory, though they are unsure if she's inherited his immunity. She decides to stay with her father regardless. Mitch struggles with learning his wife was unfaithful, and protecting his daughter from infection. Meanwhile, everyone who had contact with Emhoff begins to spread the disease around the world.
In Atlanta, representatives of the Department of Homeland Security meet with Dr. Ellis Cheever of the CDC and fear that the disease is a bio weapon terror attack over the Thanksgiving weekend. Dr. Cheever dispatches Dr. Erin Mears, an Epidemic Intelligence Service officer, to Minneapolis to begin investigating. Mears traces the outbreak to Emhoff, but after setting up triage camps in large venues, Dr. Mears becomes infected. Her evacuation is postponed, as airports close ahead of a quarantine. She later dies and is buried in a mass grave. As more and more people become infected with no cure in sight, social order begins to decay, with rampant looting of stores and homes. The U.S. President is moved underground while emergency services suffer absenteeism and no longer respond. Mitch and Jory attempt to escape to Wisconsin, but the borders are closed. 
Question: What is the full name of the person buried in a mass grave?
answer:

Dr. Ellis Cheever.
