The problem: Answer a question about this article:
Glaciers form where the accumulation of snow and ice exceeds ablation. The area in which a glacier forms is called a cirque (corrie or cwm) - a typically armchair-shaped geological feature (such as a depression between mountains enclosed by aretes) - which collects and compresses through gravity the snow which falls into it. This snow collects and is compacted by the weight of the snow falling above it forming neve. Further crushing of the individual snowflakes and squeezing the air from the snow turns it into 'glacial ice'. This glacial ice will fill the cirque until it 'overflows' through a geological weakness or vacancy, such as the gap between two mountains. When the mass of snow and ice is sufficiently thick, it begins to move due to a combination of surface slope, gravity and pressure. On steeper slopes, this can occur with as little as 15 m (50 ft) of snow-ice.
How much ice and snow is minimally necessary to begin to slide on steep glaciers?
****
The answer: 15 m (50 ft)

Songbirds and their associated symbolism appear throughout the novel. The family's last name of Finch also shares Lee's mother's maiden name. The titular mockingbird is a key motif of this theme, which first appears when Atticus, having given his children air-rifles for Christmas, allows their Uncle Jack to teach them to shoot. Atticus warns them that, although they can "shoot all the bluejays they want", they must remember that "it's a sin to kill a mockingbird". Confused, Scout approaches her neighbor Miss Maudie, who explains that mockingbirds never harm other living creatures. She points out that mockingbirds simply provide pleasure with their songs, saying, "They don't do one thing but sing their hearts out for us." Writer Edwin Bruell summarized the symbolism when he wrote in 1964, "'To kill a mockingbird' is to kill that which is innocent and harmlesslike Tom Robinson." Scholars have noted that Lee often returns to the mockingbird theme when trying to make a moral point.
Which animal serves as a symbol throughout the book?
****
The answer: Songbirds

A 2000 United States Department of the Treasury study of lending trends for 305 cities from 1993 to 1998 showed that $467 billion of mortgage lending was made by Community Reinvestment Act (CRA)-covered lenders into low and mid level income (LMI) borrowers and neighborhoods, representing 10% of all U.S. mortgage lending during the period. The majority of these were prime loans. Sub-prime loans made by CRA-covered institutions constituted a 3% market share of LMI loans in 1998, but in the run-up to the crisis, fully 25% of all sub-prime lending occurred at CRA-covered institutions and another 25% of sub-prime loans had some connection with CRA. In addition, an analysis by the Federal Reserve Bank of Dallas in 2009, however, concluded that the CRA was not responsible for the mortgage loan crisis, pointing out that CRA rules have been in place since 1995 whereas the poor lending emerged only a decade later. Furthermore, most sub-prime loans were not made to the LMI borrowers targeted by the CRA, especially in the years 20052006 leading up to the crisis. Nor did it find any evidence that lending under the CRA rules increased delinquency rates or that the CRA indirectly influenced independent mortgage lenders to ramp up sub-prime lending.
What percent of sub-prime lending occurred at CRA-covered institutions in the run-up to the financial crisis?
****
The answer: 25%

From 1820 to 1848 Sicily was shaken by upheavals, which culminated on 12 January 1848, with a popular insurrection, the first one in Europe that year, led by Giuseppe La Masa. A parliament and constitution were proclaimed. The first president was Ruggero Settimo. The Bourbons reconquered Palermo in 1849, and remained under their rule until the time of Giuseppe Garibaldi. The famous general entered Palermo with his troops (the "Thousands") on 27 May 1860. After the plebiscite later that year Palermo, along with the rest of Sicily, became part of the new Kingdom of Italy (1861).
Who regained control of Palermo in 1849?
****
The answer:
The Bourbons
