QUES: The office of Borough President was created in the consolidation of 1898 to balance centralization with local authority. Each borough president had a powerful administrative role derived from having a vote on the New York City Board of Estimate, which was responsible for creating and approving the city's budget and proposals for land use. In 1989 the Supreme Court of the United States declared the Board of Estimate unconstitutional on the grounds that Brooklyn, the most populous borough, had no greater effective representation on the Board than Staten Island, the least populous borough, a violation of the Fourteenth Amendment's Equal Protection Clause pursuant to the high court's 1964 "one man, one vote" decision.
Why was the Board of Estimate found unconstitutional?

ANS: Brooklyn, the most populous borough, had no greater effective representation on the Board than Staten Island, the least populous borough

QUES: It was during this decade that vocal house became firmly established, both in the underground and as part of the pop market, and labels such as Defected Records, Roule and Om were at the forefront of championing the emerging sound. In the mid-2000s, fusion genres such as electro house and fidget house emerged.[citation needed] This fusion is apparent in the crossover of musical styles by artists such as Dennis Ferrer and Booka Shade, with the former's production style having evolved from the New York soulful house scene and the latter's roots in techno.
Roule and Om was at the forefront of what type of Shade music?

ANS: unanswerable

QUES: Solar cookers use sunlight for cooking, drying and pasteurization. They can be grouped into three broad categories: box cookers, panel cookers and reflector cookers. The simplest solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated container with a transparent lid. It can be used effectively with partially overcast skies and will typically reach temperatures of 90–150 °C (194–302 °F). Panel cookers use a reflective panel to direct sunlight onto an insulated container and reach temperatures comparable to box cookers. Reflector cookers use various concentrating geometries (dish, trough, Fresnel mirrors) to focus light on a cooking container. These cookers reach temperatures of 315 °C (599 °F) and above but require direct light to function properly and must be repositioned to track the Sun.
What are solar cookers used for?

ANS: cooking, drying and pasteurization

QUES: The CIPA DC-004 standard requires that Japanese manufacturers of digital still cameras use either the REI or SOS techniques, and DC-008 updates the Exif specification to differentiate between these values. Consequently, the three EI techniques carried over from ISO 12232:1998 are not widely used in recent camera models (approximately 2007 and later). As those earlier techniques did not allow for measurement from images produced with lossy compression, they cannot be used at all on cameras that produce images only in JPEG format.
In what year did the three EI techniques from ISO 12232:1998 largely stop being used?

ANS:
approximately 2007 and later
