Q: Passage: As a young boy, after his mother dies, Rick Martin sees a trumpet in the window of a pawn shop. He works in a bowling alley to save up enough money to buy it. Rick grows up to be an outstanding musician (adult Rick played by Kirk Douglas), tutored by jazzman Art Hazzard. He lands a job playing for the big band of Jack Chandler, getting to know the piano player Smoke Willoughby and the beautiful singer Jo Jordan.
Chandler orders him to always play the music exactly as written. Rick prefers to improvise, and one night, during a break with Chandler's band, he leads an impromptu jam session, which gets him fired.
Jo has fallen for Rick and finds him a job in New York with a dance orchestra. One night, her friend Amy North accompanies her to hear Rick play. Amy, studying to be a psychiatrist, is a complicated young woman still disturbed by her own mother's suicide.
She claims to be incapable of feeling love, but she and Rick begin an affair, which consumes him so completely he begins to slip away from his old friends. Jo eventually tries to warn him against getting too involved with Amy, suggesting that she will hurt him because "way inside she's all mixed up"; but Amy arrives while Jo is talking to Rick, and it is revealed that the two are already married. Jo hopes he will forgive her words.
Question: What is the full name of the person that the jazzman tutors?

A: Rick Martin.

Q: Passage: Dr. Edwards arrives at a secluded island laboratory to examine Mr. Porter. Although Porter carries a deadly flesh-eating virus, he is asymptomatic and shows no signs of necrosis. Along with fellow researchers Camila and Bridget, Dr. Edwards spends two months examining Porter in isolation. Porter continually asks to see his wife, but he is continually denied.
Marcus prepares to marry wealthy heiress Kate Arias in the Dominican Republic. Mark's best friend Dobs, his brother Josh, and Josh's girlfriend Penny charter a boat and take Mark to a supposedly unpopulated island for a low key bachelor party.
Sympathetic researcher Camila creates a rapport with Porter. Frustrated with his confinement, Porter intentionally infects one of the researchers as he begins revolting against his continued isolation. Porter warns Camila that he is dangerous. Bridget becomes infected.
Josh and Penny go snorkeling and find dead sea animals littering the ocean floor. When they return to camp, Josh and Penny discover strange rashes on their skin. While Josh performs oral sex on her, Penny begins spitting up large amounts of blood and her flesh starts melting. Josh radios for help and a voice claiming to be Dr. Edwards provides him with instructions.
Realizing that they need help but are stranded, Mark and Dobs search the island and find a bunker. Inside, the two friends discover research related to the virus. They also find mutated men who attempt to kill them. Mark and Dobs are able to escape the human danger, but Dobs becomes infected.
The bunker turns out to be connected to Dr. Edwards' laboratory. Josh reunites with Mark and Dobs and they find the researchers. After formulating a plan for extraction, Bridget and Josh split off to gather Penny and wait for the boat on the beach. Dobs and Edwards also go on their own while Porter, Camila, and Marcus initiate the laboratory's self-destruct sequence.
Question: Who discovers research related to a virus?

A: Mark.

Q: Passage: Stefan Lochner (the Dombild Master or Master Stefan; c. 1410 late 1451) was a German painter working in the late "soft style" of the International Gothic. His paintings combine that era's tendency toward long flowing lines and brilliant colours with the realism, virtuoso surface textures and innovative iconography of the early Northern Renaissance. Based in Cologne, a commercial and artistic hub of northern Europe, Lochner was one of the most important German painters before Albrecht Durer. Extant works include single-panel oil paintings, devotional polyptychs and illuminated manuscripts, which often feature fanciful and blue-winged angels. Today some thirty-seven individual panels are attributed to him with confidence.
Less is known of his life. Art historians associating the Dombild Master with the historical Stefan Lochner believe he was born in Meersburg in south-west Germany around 1410, and that he spent some of his apprenticeship in the Low Countries. Records further indicate that his career developed quickly but was cut short by an early death. We know that he was commissioned around 1442 by the Cologne council to provide decorations for the visit of Emperor Frederick III, a major occasion for the city. Records from the following years indicate growing wealth and the purchase of a number of properties around the city. Thereafter he seems to have over-extended his finances and fallen into debt. Plague hit Cologne in 1451 and there, apart from the records of creditors, mention of Stephan Lochner ends; it is presumed he died that year, aged around 40.
Lochner's identity and reputation were lost until a revival of 15th-century art during the early 19th-century romantic period. Despite extensive historical research, attribution remains difficult; for centuries a number of associated works were grouped and loosely attributed to the Dombild Master, a notname taken from the Dombild Altarpiece (in English cathedral picture, also known as the Altarpiece of the City's Patron Saints) still in Cologne Cathedral. One of Durer's diary entries became key, 400 years later, in the 20th-century establishment of Lochner's identity. Only two attributed works are dated, and none are signed. His influence on successive generations of northern artists was substantial. Apart from the many direct copies made in the later 15th century, echoes of his panels can be seen in works by Rogier van der Weyden and Hans Memling. Lochner's work was praised by Friedrich Schlegel and Goethe for its qualities, especially the "sweetness and grace" of his Madonnas.
Question: What is the last name of the individual to whom, today, some thirty-seven individual panels are attributed with confidence?

A:
Lochner.
