question:
Passage: When the painting was unveiled in 1953, most Chinese critics were enthusiastic. Xu Beihong, the president of CAFA and a pioneer in using realism in oil painting, admired the manner in which the work fulfilled its political mission, but complained that because of the colors, it barely resembled an oil painting. He and others, though, saw that the painting opened a new chapter in Chinese art development. Zhu Dan, head of the People's Fine Arts Publishing House, which would reproduce the painting for the masses, argued that it was more a poster than an oil painting. Other artists stated that Dong's earlier works, such as Kazakh Shepherdess (1947) and Liberation (1949), were better examples of the new national style of art. Senior Party leaders, though, approved of the painting, as art historian Chang-Tai Hung put it, "seeing it as a testament to the young nation's evolving identity and growing confidence".Soon after the unveiling, Jiang wanted to arrange an exhibition at which government officials, including Mao, could view and publicly endorse the new Chinese art. He had connections in Mao's inner circle, and Dong and others organized it to be in conjunction with meetings at Zhongnanhai that Mao led. This was, most likely, the only time Mao attended an art exhibition after 1949. Mao visited the exhibition three times in between meetings and especially liked The Founding of the Nationthe official photograph of the event shows Mao and Zhou Enlai viewing the canvas with Dong. The chairman stared at the painting for a long time and finally said, "It is a great nation. It really is a great nation." Mao also stated that the portrayal of Dong Biwu was particularly well rendered. As Dong Biwu was in the second row, mostly hidden by the large Zhu De, Mao was most likely joking, but the favorable reaction by the country's leader assured the success of the painting.The Founding of the Nation was hailed as one of the greatest oil paintings ever by a Chinese artist by reviewers in that country, and more than 500,000 reproductions were sold in three months. Mao's praise helped boost the painting and its painter. Dong's techniques were seen as bridging the gap between the elitist medium of oil painting and popular art, and as a boost to Jiang's position that realistic art could be politically desirable. It was reproduced in primary and secondary school textbooks. The painting appeared on the front page of People's Daily in September 1953, and became an officially approved interior decoration. One English-language magazine published by the Chinese government for distribution abroad showed a model family in a modern apartment, with a large poster of The Founding of the Nation on the wall. According to Chang-Tai Hung, the painting "became a celebrated propaganda piece".
Question: What is the name of the person who had connections in Mao's inner circle?
answer:
Jiang.

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?
answer:
Chief O'Hara.

Passage: There was considerable local opposition to the Yellowstone National Park during its early years. Some of the locals feared that the regional economy would be unable to thrive if there remained strict federal prohibitions against resource development or settlement within park boundaries and local entrepreneurs advocated reducing the size of the park so that mining, hunting, and logging activities could be developed. To this end, numerous bills were introduced into Congress by Montana representatives who sought to remove the federal land-use restrictions.After the park's official formation, Nathaniel Langford was appointed as the park's first superintendent in 1872 by Secretary of Interior Columbus Delano, the first overseer and controller of the park. Langford served for five years but was denied a salary, funding, and staff. Langford lacked the means to improve the land or properly protect the park, and without formal policy or regulations, he had few legal methods to enforce such protection. This left Yellowstone vulnerable to poachers, vandals, and others seeking to raid its resources. He addressed the practical problems park administrators faced in the 1872 Report to the Secretary of the Interior and correctly predicted that Yellowstone would become a major international attraction deserving the continuing stewardship of the government. In 1874, both Langford and Delano advocated the creation of a federal agency to protect the vast park, but Congress refused. In 1875, Colonel William Ludlow, who had previously explored areas of Montana under the command of George Armstrong Custer, was assigned to organize and lead an expedition to Montana and the newly established Yellowstone Park. Observations about the lawlessness and exploitation of park resources were included in Ludlow's Report of a Reconnaissance to the Yellowstone National Park. The report included letters and attachments by other expedition members, including naturalist and mineralogist George Bird Grinnell.
Grinnell documented the poaching of buffalo, deer, elk, and antelope for hides. "It is estimated that during the winter of 18741875, not less than 3,000 buffalo and mule deer suffer even more severely than the elk, and the antelope nearly as much."As a result, Langford was forced to step down in 1877.
Question: What is the full name of the person who lacked the means to improve the land or properly protect the park?
answer:
Nathaniel Langford.
