Problem: Ricci v. DeStefano was heard by the United States Supreme Court in 2009. The case concerns White and Hispanic firefighters in New Haven, Connecticut, who upon passing their test for promotions to management were denied the promotions, allegedly because of a discriminatory or at least questionable test. The test gave 17 whites and two Hispanics the possibility of immediate promotion. Although 23% of those taking the test were African American, none scored high enough to qualify. Because of the possibility the tests were biased in violation of Title VII of the Civil Rights Act, no candidates were promoted pending outcome of the controversy. In a split 5-4 vote, the Supreme Court ruled that New Haven had engaged in impermissible racial discrimination against the White and Hispanic majority.
How many whites were given the possibility of immediate promotion as a result of taking the controversial test?
The answer is the following: 17

Problem: In recent years, Melton, Wyndham and Casey, part of the Melbourne statistical division, have recorded the highest growth rate of all local government areas in Australia. Melbourne could overtake Sydney in population by 2028, The ABS has projected in two scenarios that Sydney will remain larger than Melbourne beyond 2056, albeit by a margin of less than 3% compared to a margin of 12% today. Melbourne's population could overtake that of Sydney by 2037 or 2039, according to the first scenario projected by the ABS; primarily due to larger levels of internal migration losses assumed for Sydney. Another study claims that Melbourne will surpass Sydney in population by 2040.
Melbourne's population could overtake that of Sydney by 2037 or 2039 primarily due to what factor?
The answer is the following: larger levels of internal migration losses assumed for Sydney

Problem: The accession of Valens gave a fresh lease of life to the Arian party. He issued a decree banishing the bishops who had been deposed by Constantius, but who had been permitted by Jovian to return to their sees. The news created the greatest consternation in the city of Alexandria itself, and the prefect, in order to prevent a serious outbreak, gave public assurance that the very special case of Athanasius would be laid before the emperor. But the saint seems to have divined what was preparing in secret against him. He quietly withdrew from Alexandria, 5 October, and took up his abode in a country house outside the city. Valens, who seems to have sincerely dreaded the possible consequences of another popular outbreak, within a few weeks issued orders allowing Athanasius to return to his episcopal see. 
How did Valens get him to return?
The answer is the following:
issued orders allowing Athanasius to return to his episcopal see
