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.

Q: Passage: While no cohesive plot is apparent from the vignette style of the trailer, it can be pieced together that Batman has been murdered, and his killer remains at large. Dick Grayson is long since retired from his superhero days and raising a family with to his wife Barbara Gordon. After his former mentor's death, however, he decides to resume his crime-fighting days as Robin. Remarkably, Grayson does not take up the Nightwing identity. The filmmakers said they chose this because many people outside the comic book community are unfamiliar with Nightwing and they wanted to appeal to a wider audience.Commissioner Gordon is aware of Grayson's secret identity and assists him by supplying official documents. In addition, Gordon provides the voiceover narration at the beginning of the trailer. The head of the investigation into Batman's death is indicated to be Chief O'Hara, a character from the 1960's Batman TV series, who apparently also knows Grayson's identity (noting that Grayson's "crimefighting days are over") His role is suspicious since he strongly wants Grayson to not become involved, even to the point of aligning with Selina Kyle/Catwoman to eliminate Robin and shouting at reporter Clark Kent that he wants "him [presumably Grayson] out of the equation!" O'Hara is also seen rolling up his sleeves, preparing to assault an angry captive Gordon.

Grayson is aware of Superman's secret identity; he addresses him as "Clark". Superman apparently is also motivated (obviously from O'Hara) to discourage Grayson's return to crimefighting and three angry confrontations between the characters are shown, in and out of costume. Grayson is also angered to violence by the sight of a Superman comic book, suggesting a strongly negative history between the two. Other comic books also appear of characters from the film, including Wonder Woman and Catwoman. Fiorella used his own comic book collection for this scene. 
Question: Who aligns himself with Catwoman to eliminate Robin?

A: Chief O'Hara.

Q: Passage: Although weakened and pushed south beyond the Huai River, the Southern Song found new ways to bolster its strong economy and defend itself against the Jin dynasty. It had able military officers such as Yue Fei and Han Shizhong. The government sponsored massive shipbuilding and harbor improvement projects, and the construction of beacons and seaport warehouses to support maritime trade abroad, including at the major international seaports, such as Quanzhou, Guangzhou, and Xiamen, that were sustaining China's commerce.To protect and support the multitude of ships sailing for maritime interests into the waters of the East China Sea and Yellow Sea (to Korea and Japan), Southeast Asia, the Indian Ocean, and the Red Sea, it was necessary to establish an official standing navy. The Song dynasty therefore established China's first permanent navy in 1132, with a headquarters at Dinghai. With a permanent navy, the Song were prepared to face the naval forces of the Jin on the Yangtze River in 1161, in the Battle of Tangdao and the Battle of Caishi. During these battles the Song navy employed swift paddle wheel driven naval vessels armed with traction trebuchet catapults aboard the decks that launched gunpowder bombs. Although the Jin forces commanded by Wanyan Liang (the Prince of Hailing) boasted 70,000 men on 600 warships, and the Song forces only 3,000 men on 120 warships, the Song dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddle wheel ships. The strength of the navy was heavily emphasized after that. A century after the navy was founded it had grown in size to 52,000 fighting marines.
The Song government confiscated portions of land owned by the landed gentry in order to raise revenue for these projects, an act which caused dissension and loss of loyalty amongst leading members of Song society but did not stop the Song's defensive preparations. Financial matters were made worse by the fact that many wealthy, land-owning families—some of which had officials working for the government—used their social connections with those in office in order to obtain tax-exempt status.Although the Song dynasty was able to hold back the Jin, a new foe came to power over the steppe, deserts, and plains north of the Jin dynasty. The Mongols, led by Genghis Khan (r. 1206–1227), initially invaded the Jin dynasty in 1205 and 1209, engaging in large raids across its borders, and in 1211 an enormous Mongol army was assembled to invade the Jin. The Jin dynasty was forced to submit and pay tribute to the Mongols as vassals; when the Jin suddenly moved their capital city from Beijing to Kaifeng, the Mongols saw this as a revolt. Under the leadership of Ögedei Khan (r.1229–1241), both the Jin dynasty and Western Xia dynasty were conquered by Mongol forces. The Mongols also invaded Korea, the Abbasid Caliphate of the Middle East and the Kievan Rus'. 
Question: What people used their social connections with those in office in order to obtain tax-exempt status?

A: wealthy, land-owning families.

Q: Passage: Desegregation in Birmingham took place slowly after the demonstrations. King and the SCLC were criticized by some for ending the campaign with promises that were too vague and "settling for a lot less than even moderate demands". In fact, Sydney Smyer, president of the Birmingham Chamber of Commerce, re-interpreted the terms of the agreement. Shuttlesworth and King had announced that desegregation would take place 90 days from May 15.  Smyer then said that a single black clerk hired 90 days from when the new city government took office would be sufficient. By July, most of the city's segregation ordinances had been overturned.  Some of the lunch counters in department stores complied with the new rules. City parks and golf courses were opened again to black and white citizens.  Mayor Boutwell appointed a biracial committee to discuss further changes.  However, no hiring of black clerks, police officers, and firefighters had yet been completed and the Birmingham Bar Association rejected membership by black attorneys.The reputation of Martin Luther King Jr. soared after the protests in Birmingham, and he was lauded by many as a hero. The SCLC was much in demand to effect change in many Southern cities. In the summer of 1963, King led the March on Washington for Jobs and Freedom where he delivered his most famous speech, "I Have a Dream".
King became Time's Man of the Year for 1963 and won the Nobel Peace Prize in 1964.
Four months after the Birmingham campaign settlement, someone bombed the house of NAACP attorney Arthur Shores, injuring his wife in the attack. On September 15, 1963, Birmingham again earned international attention when Ku Klux Klan members bombed the 16th Street Baptist Church on a Sunday morning and killed four young girls.  FBI informant Gary Thomas Rowe was hired to infiltrate the KKK and monitor their activities and plans. Rowe was involved, along with the Birmingham Police, with the KKK attacks on the Freedom Riders, led by Fred Shuttlesworth, in Anniston, Alabama on May 14, 1961. In addition, Rowe and several other Klansmen also partook in the killing of Civil Rights activist Viola Liuzzo on March 25, 1965, in Lowndes County, Georgia after the Selma to Montgomery march.The Birmingham campaign inspired the Civil Rights Movement in other parts of the South. Two days after King and Shuttlesworth announced the settlement in Birmingham, Medgar Evers of the NAACP in Jackson, Mississippi demanded a biracial committee to address concerns there. On June 12, 1963, Evers was fatally shot outside his home.  He had been organizing demonstrations similar to those in Birmingham to pressure Jackson's city government. In 1965 Shuttlesworth assisted Bevel, King, and the SCLC to lead the Selma to Montgomery marches, intended to increase voter registration among black citizens. 
Question: What is the first name of the person who, with several other Klansmen partook in the killing of a Civil Rights activist?

A:
Gary.
