Example Input: You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. <sep>How do glaciers form?<sep>Layer upon layer of snow compacted and turned to ice
Example Output: Yes

Example Input: MALS was formed here more than 30 years ago. Today, 14 staff attorneys, 26 office workers and 21 University of Memphis third- year law students work out of rented offices in the old Claridge Hotel building at 109 N. Main. Offices are spartan. There are no lush rugs or stylish furniture. The large table in the conference room is simple varnished wood. Offices are small and mostly plain, except for the eclectic mix of pop art, African statuary and neon that adorns litigation director Webb Brewer's space. Brewer, who has been at the agency 20 years, said there is a need for lawyers of all stripes to help with the problems of the poor. "The private bar could meet more of the need through pro bono work, but there are still cases that involve the systemic problems for low-income people that we would need to do," said Brewer. "The legal system marketplace just doesn't serve low-income people too well, except in fee-generat-ing type cases," Brewer said. "If a poor person gets run over by a bus, an attorney might take that case because they might be able to recover part of the damage award as attorney fees. But so many of the cases we handle have to do with basic rights and a decent life. There is just no profit motive." Larry Pivnick, law professor at the University of Memphis Law School and director of political programs at MALS, said Legal Services is a great learning laboratory for law students. "There are thousands and thousands of people who have problems that never get an opportunity to appear in court," Pivnick said. "Some people may not be particularly articulate. Courts have rules that clients don't always understand." Brewer said a major focus of the agency's work involves housing. "Although a lot of our work is grant-driven, we find that the lack of safe and decent affordable housing and the prevalence of predatory lending are the biggest problems in our client population," Brewer said, referring to clients such as James. <sep>What type of work is done by MALS?<sep>Medical work

Example Input: Among the early blows struck for independence was a rebellion in the town of Olhão. On 16 June 1808, the townsfolk — armed with little more than ancient swords, spears, and stones — attacked and captured the local French garrison. It's said that a party of local men then set sail from Olhão all the way to Brazil, without maps or navigational aids, to tell the king of the insurrection. The real battle, however, was waged under the leadership of the Duke of Wellington, whose coalition forces expelled the French after two years of bitter fighting. The war left Portugal further weakened, and in 1822 its major empire outpost, Brazil, declared independence. At the same time, a dispute over the crown continually raged between Pedro IV, the absentee monarch who preferred to reign as Emperor of Brazil rather than return to Portugal, and his brother Miguel. The power struggle, with strong overtones of absolutism versus liberalism, excited the interest and intervention of other powers. With British help, Pedro defeated Miguel off Cape St. Vincent in 1833, and his expeditionary force marched to Lisbon. Pedro took the throne, though armed struggle continued for months and the lingering bitterness long after that. By 1892 Portugal, racked by wars and the continuing expense of maintaining its African colonies (including those of Mozambique and Angola), declared itself bankrupt. The seeds of discontent with absolutist rule were sown. Kingdom's End Bloodshed would haunt the remaining years of the Portuguese monarchy. On 1 February 1908, the royal family was riding in an open carriage along the Lisbon river front plaza, Terreiro do Paço, when an assassin opened fire and killed King Carlos and the heir to the throne, Prince Luis Filipe. The prince's younger brother, Prince Manuel, was also hit, but he survived and was thus propelled to the throne at the tender age of 19. Amid republican agitation, a surprise uprising led by elements within the armed forces deposed Manuel in 1910. Having ruled for less than three years, Manuel died in exile in 1932 in England. The sudden end of more than seven centuries of monarchy brought confusion and crisis to the country. Presidents and prime ministers were ushered into and out of office an unbelievable 45 times between 1910 and 1926, until a military revolution suspended Portugal's problematic democracy. <sep>What was the power struggle that had strong overtones of absolutism versus liberalism?<sep>A dispute over the crown between Pedro IV and his brother Miguel
