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: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?

A: Broderick.

Q: Passage: Stereolab's music is politically and philosophically charged. Dave Heaton of PopMatters said that the group "[uses] lyrics to convey ideas while using them for the pleasurable way the words sound." The lyrics of the 2006 compilation Fab Four Suture, contains themes of war, governments that suppress freedom, and "the powerlessness that everyday people feel in the face of it all", in contrast to "humans [working] together, [treating] each other like people, and [pushing] for governments that would do the same." Lætitia Sadier, who writes the group's lyrics, was influenced by both the Situationist philosophy Society of the Spectacle by Marxist theorist Guy Debord, and her anger towards the Iraq War. The Surrealist, as well as the Situationist cultural and political movements were also influences, as stated by Sadier and Gane in a 1999 Salon interview.Critics have seen Marxist allusions in the band's lyrics, and have gone so far as to call the band members themselves Marxist. Music journalist Simon Reynolds commented that Sadier's lyrics tend to lean towards Marxist social commentary rather than "affairs of the heart". The 1994 single "Ping Pong" has been put forward as evidence in regard to these alleged views. In the song, Sadier sings "about capitalism's cruel cycles of slump and recovery" with lyrics that constitute "a plainspoken explanation of one of the central tenets of Marxian economic analysis" (said critics Reynolds and Stewart Mason, respectively).Band members have resisted attempts to link the group and its music to Marxism. In a 1999 interview, Gane stated that "none of us are Marxists ... I've never even read Marx." Gane said that although Sadier's lyrics touch on political topics, they do not cross the line into "sloganeering". Sadier also said that she had read very little Marx. In contrast, Cornelius Castoriadis, a radical political philosopher but strong critic of Marxism, has been cited as a marking influence in Sadier's thinking. The name of her side project, Monade, and its debut album title, Socialisme ou Barbarie, are also references to the work of Castoriadis.Stereolab's album and song titles occasionally reference avant-garde political groups and artists. Gane said that the title of their 1999 album Cobra and Phases Group Play Voltage in the Milky Night contains the names of two Surrealist organisations, "CoBrA" and "Phases Group", The title of the song "Brakhage" from Dots and Loops (1997), is a nod to experimental filmmaker Stan Brakhage. Other examples are the 1992 compilation Switched On, named after Wendy Carlos' 1968 album Switched On Bach, and the 1993 song "Jenny Ondioline", an interlock of inventor Georges Jenny and his instrument the Ondioline. 
Question: What is the full name of the critic who describes the lyrics to Ping Pong as "a plainspoken explanation of one of the central tenets of Marxian economic analysis"?

A:
Stewart Mason.
