Please answer this: Given the following context:  A "skybike", a one-man, open-cockpit flying machine, attacks Dogen. Dogen shoots it down and finds one of Syn's crystals on the pilot's body. Carved into the crystal is a symbol of a dead tree. Dogen finds a murdered prospector, whose young daughter Dhyana saw him killed by Baal, Jared Syn's half-cyborg son. Baal sprayed the man with a green liquid that caused a nightmare dream-state, in which Syn appeared and executed him with a crystal. Dogen convinces Dhyana to help him find Syn. Dhyana takes Dogen to Zax, who identifies the crystal as a lifeforce storage device. Dhyana tells them about the ancient Cyclopians who once used such devices and says the only power against it is a magic mask located in their lost city. Zax affirms this and directs Dogen to find a prospector named Rhodes in the nearby mining town of Zhor. Dogen and Dhyana are blocked by vehicles driven by nomads commanded by Baal, who sprays Dogen with the green liquid, paralyzing him. Dhyana drives them off and cares for Dogen, who in the dream world finds Syn and Baal looming over him. Syn fails to pull Dogen away from Dhyana: their will is too strong. Dogen awakes, but Dhyana is suddenly teleported away. A summoned monster appears in her place and fires electric bolts at him. Dhyana simultaneously faces Syn in his lair. Dogen shorts-out the creature, and it vanishes. Dogen arrives in Zhor and finds Rhodes, a washed-up soldier, in a bar. Rhodes denies the lost city's existence and refuses to get involved. Dogen leaves and comes upon a group of miners beating a captured nomad soldier. Dogen assists him, and the miners turn hostile. Dogen is out-gunned until Rhodes helps him defeat the miners.  answer the following question:  What item can the magic mask be used against?
++++++++
Answer: the crystal

Problem: Given the following context:  Martin Luther King Jr.'s presence in Birmingham was not welcomed by all in the black community.  A local black attorney complained in Time that the new city administration did not have enough time to confer with the various groups invested in changing the city's segregation policies. Black hotel owner A. G. Gaston agreed. A white Jesuit priest assisting in desegregation negotiations attested the "demonstrations [were] poorly timed and misdirected".Protest organizers knew they would meet with violence from the Birmingham Police Department and chose a confrontational approach to get the attention of the federal government. Wyatt Tee Walker, one of the SCLC founders and the executive director from 1960 to 1964, planned the tactics of the direct action protests, specifically targeting Bull Connor's tendency to react to demonstrations with violence: "My theory was that if we mounted a strong nonviolent movement, the opposition would surely do something to attract the media, and in turn induce national sympathy and attention to the everyday segregated circumstance of a person living in the Deep South." He headed the planning of what he called Project C, which stood for "confrontation". Organizers believed their phones were tapped, so to prevent their plans from being leaked and perhaps influencing the mayoral election, they used code words for demonstrations.The plan called for direct nonviolent action to attract media attention to "the biggest and baddest city of the South". In preparation for the protests, Walker timed the walking distance from the 16th Street Baptist Church, headquarters for the campaign, to the downtown area. He surveyed the segregated lunch counters of department stores, and listed federal buildings as secondary targets should police block the protesters' entrance into primary targets such as stores, libraries, and all-white churches.  answer the following question:  What is the last name of the person who surveyed segregated lunch counters?

A: Walker

Q: Given the following context:  Nathu La is located on the 563 km (350 mi) Old Silk Route, an offshoot of the historic Silk Road. The Old Silk Route connects Lhasa in Tibet to the plains of Bengal to the south. In 1815, trade volume increased after the British annexed territories belonging to the Sikkimese, Nepalese, and Bhutanese. The potential of Nathu La was realised in 1873, after the Darjeeling Deputy Commissioner published a report on the strategic importance of mountain passes between Sikkim and Tibet. In December 1893, the Sikkimese monarchy and Tibetan rulers signed an agreement to increase trade between the two nations. The agreement culminated in 1894 when the trade pass was opened. Nathu La played a vital role in the 1903–1904 British expedition to Tibet, which sought to prevent the Russian Empire from interfering in Tibetan affairs and thus gaining a foothold in the region. In 1904, Major Francis Younghusband, serving as the British Commissioner to Tibet, led a successful mission through Nathu La to capture Lhasa. This led to the setting up of trading posts at Gyantse and Gartok in Tibet, and gave control of the surrounding Chumbi Valley to the British. The following November, China and Great Britain ratified an agreement approving trade between Sikkim and Tibet. In 1947 and 1948, a popular vote for Sikkim to join newly independent India failed and Indian Prime Minister Jawaharlal Nehru agreed to a special protectorate status for Sikkim. Sikkim agreed to be a protectorate nation and Indian troops were allowed to man its borders, including Nathu La. During this period, more than 1,000 mules and 700 people were involved in cross-border trade through Nathu La. In 1949, when the Tibetan government expelled the Chinese living there, most of the displaced Chinese returned home through the Nathu La–Sikkim–Kolkata route.The current Dalai Lama, Tenzin Gyatso, used this pass to travel to India for the 2,500th birthday celebration of Gautama Buddha, which was held between November 1956 and February 1957. Later, on 1 September 1958, Nehru,...  answer the following question:  What is the name of the country that the people of Sikkim attempted to join through vote and failed twice in the 1940s?
A:
India
