In 2002, Queen's "Bohemian Rhapsody" was voted "the UK's favourite hit of all time" in a poll conducted by the Guinness World Records British Hit Singles Book. In 2004 the song was inducted into the Grammy Hall of Fame. Many scholars consider the "Bohemian Rhapsody" music video ground-breaking, and credit it with popularising the medium. Rock historian Paul Fowles states the song is "widely credited as the first global hit single for which an accompanying video was central to the marketing strategy". It has been hailed as launching the MTV age. Acclaimed for their stadium rock, in 2005 an industry poll ranked Queen's performance at Live Aid in 1985 as the best live act in history. In 2007, they were also voted the greatest British band in history by BBC Radio 2 listeners.
What Queen song was inducted into the Grammy Hall of Fame in 2004?
A: Bohemian Rhapsody

Further problems hampered the Arctic project after the commencement of drilling in 2012, as Shell dealt with a series of issues that involved air permits, Coast Guard certification of a marine vessel and severe damage to essential oil-spill equipment. Additionally, difficult weather conditions resulted in the delay of drilling during mid-2012 and the already dire situation was exacerbated by the "Kulluk" incident at the end of the year. Royal Dutch Shell had invested nearly US$5 billion by this stage of the project.
What conditions caused the delay of drilling in mid-2012?
A: difficult weather

In the early 19th century, the role of Utrecht as a fortified town had become obsolete. The fortifications of the Nieuwe Hollandse Waterlinie were moved east of Utrecht. The town walls could now be demolished to allow for expansion. The moats remained intact and formed an important feature of the Zocher plantsoen, an English style landscape park that remains largely intact today. Growth of the city increased when, in 1843, a railway connecting Utrecht to Amsterdam was opened. After that, Utrecht gradually became the main hub of the Dutch railway network. With the industrial revolution finally gathering speed in the Netherlands and the ramparts taken down, Utrecht began to grow far beyond the medieval centre. In 1853, the Dutch government allowed the bishopric of Utrecht to be reinstated by Rome, and Utrecht became the centre of Dutch Catholicism once more. From the 1880s onward neighbourhoods such as Oudwijk, Wittevrouwen, Vogelenbuurt to the East, and Lombok to the West were developed. New middle class residential areas, such as Tuindorp and Oog in Al, were built in the 1920s and 1930s. During this period, several Jugendstil houses and office buildings were built, followed by Rietveld who built the Rietveld Schröder House (1924), and Dudok's construction of the city theater (1941).
What became obsolete in the 1900's?
A: unanswerable

Compounds that contain a carbon-copper bond are known as organocopper compounds. They are very reactive towards oxygen to form copper(I) oxide and have many uses in chemistry. They are synthesized by treating copper(I) compounds with Grignard reagents, terminal alkynes or organolithium reagents; in particular, the last reaction described produces a Gilman reagent. These can undergo substitution with alkyl halides to form coupling products; as such, they are important in the field of organic synthesis. Copper(I) acetylide is highly shock-sensitive but is an intermediate in reactions such as the Cadiot-Chodkiewicz coupling and the Sonogashira coupling. Conjugate addition to enones and carbocupration of alkynes can also be achieved with organocopper compounds. Copper(I) forms a variety of weak complexes with alkenes and carbon monoxide, especially in the presence of amine ligands.
What is produced when copper compounds are treated with organolithium reagents?
A:
Gilman reagent
