In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX 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?
[EX A]: Mark.

[EX Q]: Passage: Prose works in Sanskrit was prolific during this era as well. Important mathematical theories and axioms were postulated by Mahaviracharya, a native of Gulbarga, who belonged to the Karnataka mathematical tradition and was patronised by King Amoghavarsha I. His greatest contribution was Ganitasarasangraha, a writing in 9 chapters. Somadevasuri of 950 wrote in the court of Arikesari II, a feudatory of Rashtrakuta Krishna III in Vemulavada. He was the author of Yasastilaka champu, Nitivakyamrita and other writings. The main aim of the champu writing was to propagate Jain tenets and ethics. The second writing reviews the subject matter of Arthashastra from the standpoint of Jain morals in a clear and pithy manner. Ugraditya, a Jain ascetic from Hanasoge in the modern Mysore district wrote a medical treatise called Kalyanakaraka. He delivered a discourse in the court of Amoghavarsha I encouraging abstinence from animal products and alcohol in medicine.Trivikrama was a noted scholar in the court of King Indra III. His classics were Nalachampu (915), the earliest in champu style in Sanskrit, Damayanti Katha, Madalasachampu and Begumra plates. Legend has it that Goddess Saraswati helped him in his effort to compete with a rival in the king's court. Jinasena was the spiritual preceptor and guru of Amoghavarsha I. A theologian, his contributions are Dhavala and Jayadhavala (written with another theologian Virasena). These writings are named after their patron king who was also called Athishayadhavala. Other contributions from Jinasena were Adipurana, later completed by his disciple Gunabhadra, Harivamsha and Parshvabhyudaya.
Question: What is the name of what is name after their patron king?
[EX A]: Dhavala.

[EX Q]: Passage: In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research. They synthesized 14C using the laboratory's cyclotron accelerator and soon discovered that the atom's half-life was far longer than had been previously thought. This was followed by a prediction by Serge A. Korff, then employed at the Franklin Institute in Philadelphia, that the interaction of thermal neutrons with 14N in the upper atmosphere would create 14C. It had previously been thought that 14C would be more likely to be created by deuterons interacting with 13C. At some time during World War II, Willard Libby, who was then at Berkeley, learned of Korff's research and conceived the idea that it might be possible to use radiocarbon for dating.In 1945, Libby moved to the University of Chicago where he began his work on radiocarbon dating. He published a paper in 1946 in which he proposed that the carbon in living matter might include 14C as well as non-radioactive carbon. Libby and several collaborators proceeded to experiment with methane collected from sewage works in Baltimore, and after isotopically enriching their samples they were able to demonstrate that they contained 14C. By contrast, methane created from petroleum showed no radiocarbon activity because of its age. The results were summarized in a paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages. For example, two samples taken from the tombs of two Egyptian kings, Zoser and Sneferu, independently dated to 2625 BC plus or minus 75 years, were dated by radiocarbon measurement to an average of 2800 BC plus or minus 250 years. These results were published in Science in 1949. Within 11 years of their announcement, more than 20 radiocarbon dating laboratories had been set up worldwide. In 1960, Libby was awarded the Nobel Prize in Chemistry for this work.
Question: What are the last names of the people who, within 11 years of their announcement, more than 20 radiocarbon dating laboratories had been set up worldwide?
[EX A]:
Libby.
