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: The film begins in a parking lot in which a teenage filmmaker named Eric is attempting to document the faux-gangsta lifestyle enjoyed by Allison Lang and her boyfriend Toby's (Mike Vogel) gang of white upper-class teenagers living in the Pacific Palisades neighborhood. A brawl ensues between Toby's gang and another gang, which ends with both sides fleeing just before police arrive. Later that night, Toby's gang goes to a party at Eric's house, and Allison's relationship with Toby as well as her other friends Emily and Sam is further revealed. At the end of the party, Allison performs oral sex on her boyfriend.
The next day, Allison meets with her father, Stuart, at work to discuss family problems, the awkward conversation revealing the virtually non-existent relationship Allison has with her parents. Afterwards, she and her friends drive downtown into East LA, intent on buying marijuana, eventually encountering Mexican drug dealer Hector and his crew. Toby and Hector make a deal, but Toby believes that Hector did not sell him enough for what he paid, and attempts to confront Hector, who pulls a gun on him, humiliating him in front of his friends. Allison persuades Hector to leave Toby alone. 
Question: Where do the gangs have a brawl?
[A]: parking lot.


[Q]: Passage: Wyoming's territorial Governor Francis E. Warren visited Rock Springs on September 3, 1885, the day after the riot, to make a personal assessment. After his trip to Rock Springs, Warren traveled to Evanston, where he sent telegrams to U.S. President Grover Cleveland appealing for federal troops. Back in Rock Springs, the riot had calmed, but the situation was still unstable. Two companies of the United States Army's 7th Infantry arrived on September 5, 1885. One company, under the command of a Lieutenant Colonel Anderson, was stationed in Evanston, Wyoming; the other, under a Colonel Chipman, was stationed in Rock Springs. At Camp Murray, Utah Territory, Colonel Alexander McDowell McCook was ordered to augment the garrison sent to Wyoming with six more companies.On September 9, 1885, one week after the massacre, six companies of soldiers arrived in Wyoming. Four of the six companies then escorted the Chinese back to Rock Springs. Once back in Rock Springs, the Chinese laborers found scorched tracts of land where their homes once stood. The mining company had buried only a few dead; others remained lying in the open, mangled, decomposing, and partially eaten by dogs, hogs, or other animals.The situation in Rock Springs was stabilized as early as September 15, when Warren first requested the removal of federal troops, but the mines at Rock Springs remained closed for a time. On September 30, 1885, white miners, mostly Finnish immigrants who were members of the Knights of Labor, walked out of mines in Carbon County, Wyoming, in protest of the company's continued use of Chinese miners. In Rock Springs, the white miners were not back at work in late September, because the company still used Chinese labor. Rock Springs steadily became quieter, and, on October 5, 1885, emergency troops, except for two companies, were removed. However, the temporary posts of Camp Medicine Butte, established in Evanston, and of Camp Pilot Butte, in Rock Springs, remained long after the riot. Camp Pilot Butte closed in 1899 after the onset of the Spanish–American War.The labor strike was unsuccessful, and the miners went back to work within a couple of months. The national Knights of Labor organization refused to support the Carbon strike and the hold out by white miners in Rock Springs following the Rock Springs Riot. The organization avoided supporting the miners along the Union Pacific Railroad, because it did not want to be seen as condoning the violence at Rock Springs. When the Union Pacific Coal Department reopened the mines, it fired 45 white miners connected to the violence. 
Question: What is the full name of the person that contacted the U.S. President?
[A]: Francis E. Warren.


[Q]: Passage: The northern gannet is not heavily predated. The only known habitual natural predators of adults are bald eagles and white-tailed eagles. Predators of eggs and nestlings include the great black-backed gull and American herring gull, common ravens, ermine, and red fox. Attacks at sea are insignificant though large sharks and seals may rarely snatch a gannet out at sea.Kleptoparasitism by skuas, particularly the great skua, occurs at breeding sites. The skua chases its victim until it disgorges its stomach contents, providing a meal for the attacker. Skuas may catch the tip of the gannet's wing, causing it to fall into the sea, or seize the tail to tip its victim into the water. The gannet is only released when it has regurgitated its catch.External parasites include feather lice, although there are relatively few species and none are found on the head. As with grebes and divers it may be that the short head feathers provide insufficient cover for the parasite. In one species, Michaelichus bassani, immature lice are found in the membranes lining the subcutaneous air-cells. Ixodes mites include the widespread I. uriae.The spiny-headed worm Corynosoma tunitae appears to occur only in gannets and closely related seabird families such as the cormorants. The tapeworm Tetrabothrius bassani adsorbs toxic heavy metals at a higher concentration than the gannet's own tissues, with an average 12 times as much cadmium as the gannet's pectoral muscles and 7–10 times the lead level of the bird's kidney and liver. Since levels of these toxic metals are detectable in the parasite earlier than in the host, the tapeworm might be used as an early indicator of marine pollution. 
Question: What can levels of toxic metals in its parasites tell us might be present in the environment of the northern gannet?
[A]:
marine pollution.
