PROBLEM: Passage: Throughout its existence, Warsaw has been a multi-cultural city. According to the 1901 census, out of 711,988 inhabitants 56.2% were Catholics, 35.7% Jews, 5% Greek orthodox Christians and 2.8% Protestants. Eight years later, in 1909, there were 281,754 Jews (36.9%), 18,189 Protestants (2.4%) and 2,818 Mariavites (0.4%). This led to construction of hundreds of places of religious worship in all parts of the town. Most of them were destroyed in the aftermath of the Warsaw Uprising of 1944. After the war, the new communist authorities of Poland discouraged church construction and only a small number were rebuilt. Question: Of Warsaw's inhabitants in 1901, what percentage was Catholic?

SOLUTION: 56.2%

PROBLEM: Passage: Islamist movements such as the Muslim Brotherhood, 'are well known for providing shelters, educational assistance, free or low cost medical clinics, housing assistance to students from out of town, student advisory groups, facilitation of inexpensive mass marriage ceremonies to avoid prohibitively costly dowry demands, legal assistance, sports facilities, and women's groups.' All this compares very favourably against incompetent, inefficient, or neglectful governments whose commitment to social justice is limited to rhetoric. Question: Why has the Muslim Brotherhood facilitated inexpensive mass marriage ceremonies?

SOLUTION: avoid prohibitively costly dowry demands

PROBLEM: Passage: In 2010 the Amazon rainforest experienced another severe drought, in some ways more extreme than the 2005 drought. The affected region was approximate 1,160,000 square miles (3,000,000 km2) of rainforest, compared to 734,000 square miles (1,900,000 km2) in 2005. The 2010 drought had three epicenters where vegetation died off, whereas in 2005 the drought was focused on the southwestern part. The findings were published in the journal Science. In a typical year the Amazon absorbs 1.5 gigatons of carbon dioxide; during 2005 instead 5 gigatons were released and in 2010 8 gigatons were released. Question: How many areas were impacted by the the death of vegetation in the 2010 drought?

SOLUTION:
three epicenters
