Passage: In 1823, brash naval officer David Farragut boards the Essex and informs its commander, David Porter, that the Navy is commandeering the ship for a top-secret mission. Although the crew is overdue for shore leave, Porter, a cold, efficient leader, lies to them in order to coerce them to volunteer for the dangerous assignment. Farragut soon reunites with his old shipmate, Chief Petty Officer Link, who tries to convince him that Porter, who years earlier trained Farragut harshly in an attempt to teach him patience and discipline, is not as heartless as he appears. This starts to show itself when Porter later reconciles with Farragut about their past and agree to be civil with one another.
Once the ship is at sea, Porter and Farragut open their orders and are dismayed to discover their mission: to disguise themselves as pirates, with no ties to or protection from the United States, in order to track down pirates raiding the West Indies. One night soon after, Farragut is in charge of the ship when a storm hits. Link becomes trapped beneath a keg of rum from which he has tried to sneak a drink and Farragut is forced to break the ship's rudder to rescue him. Porter discovers the damage, but even when he threatens to court-martial Farragut, the officer refuses to inform on Link.
Within days, the supplies begin to run out, one of the crew contracts scurvy, and Porter steers the rudderless Essex to the West Indies for repairs and supplies. Farragut grows frustrated with the slow drift and, although Porter forbids anyone to enter the shark-infested waters, he tries to repair the rudder himself. When a shark attacks and Farragut's rope catches on a barnacle, he is barely rescued in time, and Porter chastises him again. Six days later, the men finally reach land and Porter orders Farragut and Link to gather supplies.
Question: What is the full name of the character who Link believes is not as heartless as he appears?
David Porter.

Passage: In 1933, Lewis Tater, an aspiring novelist who harbors dreams of becoming the next Zane Grey, decides to leave his family home in Iowa to go to the University of Titan in Nevada so he can soak up the western atmosphere. He arrives to find that there is no university, only a mail order correspondence course scam run by two crooks out of the local hotel. He tries to spend the night at the hotel, but is attacked by one of the men in an attempted robbery. He escapes his attacker, grabs his suitcase, and steals their car to get away, but after awhile it runs out of gas. He looks in the car trunk, and finds a toolbox containing a revolver and ammunition. Afraid the two crooks are still in pursuit of him, he takes the tool box and his suitcase and walks off into the desert.
Wandering and exhausted, the next morning he happens upon a threadbare film-unit from Tumbleweed Productions grinding out a "B" western. Later that day, he catches a lift with the cowboy actors to Los Angeles. After applying for work at Tumbleweed, he is referred by crusty old extra Howard Pike to the Rio, a western-themed restaurant. While washing dishes at the Rio, he is called by Tumbleweed, where Howard mentors him to be an actor. After proving himself as a stuntman, unit manager Kessler offers him a speaking role. Tater then falls in love with spunky script girl Miss Trout. Meanwhile, the crooks trace him to Los Angeles to retrieve the safe-box containing their money that was in the car stolen by Lewis.
Question: What is the last name of the person who the crooks trace to Los Angeles?
Tater.

Passage: The growing Polish-Soviet tension was beginning to strain Western-Soviet relations at a time when the Poles' importance to the Allies, significant in the first years of the war, was beginning to fade, due to the entry into the conflict of the military and industrial giants, the Soviet Union and the United States. In retrospective review of records, both British Prime Minister Winston Churchill and U.S. President Franklin D. Roosevelt were increasingly torn between their commitments to their Polish ally and the demands by Stalin and his diplomats.According to the Polish diplomat Edward Bernard Raczynski, Raczynski and General Sikorski met privately with Churchill and Alexander Cadogan on 15 April 1943, and told them the Poles had proof the Soviets were responsible for the massacre. Raczynski reports Churchill, "without committing himself, showed by his manner that he had no doubt of it". Churchill said "The Bolsheviks can be very cruel". However, at the same time, on 24 April 1943, Churchill assured the Soviets: "We shall certainly oppose vigorously any 'investigation' by the International Red Cross or any other body in any territory under German authority. Such investigation would be a fraud and its conclusions reached by terrorism". Unofficial or classified UK documents concluded Soviet guilt was a "near certainty", but the alliance with the Soviets was deemed to be more important than moral issues; thus the official version supported the Soviets, up to censoring any contradictory accounts. Churchill asked Owen O'Malley to investigate the issue, but in a note to the Foreign Secretary he noted: "All this is merely to ascertain the facts, because we should none of us ever speak a word about it." O'Malley pointed out several inconsistencies and near impossibilities in the Soviet version. Later, Churchill sent a copy of the report to Roosevelt on 13 August 1943. The report deconstructed the Soviet account of the massacre and alluded to the political consequences within a strongly moral framework but recognized there was no viable alternative to the existing policy. No comment by Roosevelt on the O'Malley report has been found. Churchill's own post-war account of the Katyn affair gives little further insight. In his memoirs, he refers to the 1944 Soviet inquiry into the massacre, which found the Germans responsible, and adds, "belief seems an act of faith".
Question: What was the full name of the person Churchill asked to conduct an investigation?
Owen O'Malley.
