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.

Example Input: Passage: In 1943, in preparation for overseas deployment, 400 pilots and 3,600 crewmen of the 351st Bombardment Group assemble at a Colorado air base. Arriving in England, as part of the Eighth Air Force, the 351st BG is welcomed by the Royal Air Force and begins training, attending daily lectures on security. Their first mission flying Boeing B-17 Flying Fortress bombers has the armada departing at 15-second intervals.
The first mission of the 351st on Fortress Europe, after fighting through Luftwaffe defenders, is a success, with all 20 B-17s returning safely back to base. The danger of flying in massed formation, however, is brought home in training, when a collision takes place over the home base. Missions are also not always without casualties and 351st bombers are shot down.  Wounded airmen who make it back to base, are cared for at a nearby hospital. When bombers are all shot up, the ground crew works up to 90-hour periods to put them back into service.
As the mission tallies build, the men partake in activities at the base, including games, socializing and worship. The U.S.O. brings entertainers such as Bob Hope while the Red Cross provides the men with rest and recreation. During special parades, commanders of the 8th Air Force bestow medals for exceptional service and sacrifice.
The 351st participates in a big mission into Germany and after flying for about three hours, the B-17s' fighter escort turns back. As the bombers near their target to drop incendiary and anti-personnel bombs, enemy fighter aircraft appear and intense flak comes up from the ground. After a long battle, the 351st returns to base, ready to fight again until the war is over. 
Question: What is the formal name for the armada?
Example Output: 351st Bombardment Group.

Example Input: 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?
Example Output: Broderick.

Example Input: Passage: Will Rodman, a scientist at the San Francisco biotech company Gen-Sys, is testing the viral-based drug ALZ-112 on chimpanzees to find a cure for Alzheimer's disease. ALZ-112 is given to a chimp named Bright Eyes, greatly increasing her intelligence. But then, during Will's presentation for the drug, Bright Eyes is forced from her cage, goes on a rampage and is shot to death. Will's boss Steven Jacobs terminates the project and has the chimps slaughtered. However, Will's assistant Robert Franklin discovers that the reason for Bright Eyes' rampage was that she had recently given birth to an infant chimp. Will reluctantly agrees to take in the chimp, who is named Caesar. Will learns that Caesar has his mother's intelligence, through being exposed to ALZ-112 in her womb, and decides to raise him. Three years later, Will introduces Caesar to the redwood forest at Muir Woods National Monument. Meanwhile, Will treats his dementia-suffering father Charles with ALZ-112, which seems to restore his cognitive ability. 
Question: What is the name of the infant chimp's mother?
Example Output:
Bright Eyes.
