Problem: The Greater Hyderabad Municipal Corporation (GHMC) oversees the civic infrastructure of the city's 18 "circles", which together encompass 150 municipal wards. Each ward is represented by a corporator, elected by popular vote. The corporators elect the Mayor, who is the titular head of GHMC; executive powers rest with the Municipal Commissioner, appointed by the state government. The GHMC carries out the city's infrastructural work such as building and maintenance of roads and drains, town planning including construction regulation, maintenance of municipal markets and parks, solid waste management, the issuing of birth and death certificates, the issuing of trade licences, collection of property tax, and community welfare services such as mother and child healthcare, and pre-school and non-formal education. The GHMC was formed in April 2007 by merging the Municipal Corporation of Hyderabad (MCH) with 12 municipalities of the Hyderabad, Ranga Reddy and Medak districts covering a total area of 650 km2 (250 sq mi).:3 In the 2016 municipal election, the Telangana Rashtra Samithi formed the majority and the present Mayor is Bonthu Ram Mohan. The Secunderabad Cantonment Board is a civic administration agency overseeing an area of 40.1 km2 (15.5 sq mi),:93 where there are several military camps.:2 The Osmania University campus is administered independently by the university authority.:93
How much area, in square miles, does the GHMC oversee?
The answer is the following: 250 sq mi

Problem: On 15 September the Luftwaffe made two large daylight attacks on London along the Thames Estuary, targeting the docks and rail communications in the city. Its hope was to destroy its targets and draw the RAF into defending them, allowing the Luftwaffe to destroy their fighters in large numbers, thereby achieving an air superiority. Large air battles broke out, lasting for most of the day. The first attack merely damaged the rail network for three days, and the second attack failed altogether. The air battle was later commemorated by Battle of Britain Day. The Luftwaffe lost 18 percent of the bombers sent on the operations that day, and failed to gain air superiority.
What two targets were the Luftwaffe trying to destroy?
The answer is the following: docks and rail communications

Problem: The first appearance of the term 'affirmative action' was in the National Labor Relations Act, better known as the Wagner Act, of 1935.:15 Proposed and championed by U.S. Senator Robert F. Wagner of New York, the Wagner Act was in line with President Roosevelt's goal of providing economic security to workers and other low-income groups. During this time period it was not uncommon for employers to blacklist or fire employees associated with unions. The Wagner Act allowed workers to unionize without fear of being discriminated against, and empowered a National Labor Relations Board to review potential cases of worker discrimination. In the event of discrimination, employees were to be restored to an appropriate status in the company through 'affirmative action'. While the Wagner Act protected workers and unions it did not protect minorities, who, exempting the Congress of Industrial Organizations, were often barred from union ranks.:11 This original coining of the term therefore has little to do with affirmative action policy as it is seen today, but helped set the stage for all policy meant to compensate or address an individual's unjust treatment.[citation needed]
Who did employers routinely blacklist of fire?
The answer is the following: employees associated with unions

Problem: Zinc serves a purely structural role in zinc fingers, twists and clusters. Zinc fingers form parts of some transcription factors, which are proteins that recognize DNA base sequences during the replication and transcription of DNA. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.
How many amino acids do the Zn2+ ions bind to?
The answer is the following:
four
