QUES: Located in Chicago's Lake View neighborhood, Wrigley Field sits on an irregular block bounded by Clark and Addison Streets and Waveland and Sheffield Avenues. The area surrounding the ballpark is typically referred to as Wrigleyville. There is a dense collection of sports bars and restaurants in the area, most with baseball inspired themes, including Sluggers, Murphy's Bleachers and The Cubby Bear. Many of the apartment buildings surrounding Wrigley Field on Waveland and Sheffield Avenues have built bleachers on their rooftops for fans to view games and other sell space for advertisement. One building on Sheffield Avenue has a sign atop its roof which says "Eamus Catuli!" which is Latin for "Let's Go Cubs!" and another chronicles the time since the last Division title, pennant, and World Series championship. The 02 denotes two years since the 2008 NL Central title, 65 years since the 1945 pennant and 102 years since the 1908 World Series championship. On game days, many residents rent out their yards and driveways to people looking for parking spots. The uniqueness of the neighborhood itself has ingrained itself into the culture of the Chicago Cubs as well as the Wrigleyville neighborhood, and has led to being used for concerts and other sporting events, such as the 2010 NHL Winter Classic between the Chicago Blackhawks and Detroit Red Wings, as well as a 2010 NCAA men's football game between the Northwestern Wildcats and Illinois Fighting Illini.

What have many apartment buildings surrounding Wrigley Field built on their rooftops?
What is the answer?
ANS: bleachers

QUES: Travel and tourism continue to be extremely important for Portugal, with visitor numbers forecast to increase significantly in the future.[citation needed] However, the increasing competition from Eastern European destinations continues to develop, with the presence of similar attractions that are often cheaper in countries such as Croatia. Consequently, it has been necessary for the country to focus upon its niche attractions, such as health, nature and rural tourism, to stay ahead of its competitors.
How does Portugal compete with other areas for tourists?

ANS: focus upon its niche attractions

The Basilica of Saint Denis is generally cited as the first truly Gothic building, however the distinction is best reserved for the choir, of which the ambulatory remains intact. Noyon Cathedral, also in France, saw the earliest completion of a rebuilding of an entire cathedral in the new style from 1150 to 1231. While using all those features that came to be known as Gothic, including pointed arches, flying buttresses and ribbed vaulting, the builders continued to employ many of the features and much of the character of Romanesque architecture including round-headed arch throughout the building, varying the shape to pointed where it was functionally practical to do so.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is one of the features that have come to be considered as an important part of the Gothic style?
Ah, so.. ribbed vaulting

Question: The Vikings established Danelaw over much of the eastern and northern part of England with its boundary roughly stretching from London to Chester. It was an area of political and geographical control imposed by the Viking incursions which was formally agreed to by the Danish warlord, Guthrum and west-Saxon king, Alfred the Great in 886 AD. The Anglo-Saxon Chronicle recorded that London was "refounded" by Alfred the Great in 886. Archaeological research shows that this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls. London then grew slowly until about 950, after which activity increased dramatically.
Try to answer this question if possible: Danelaw, established by the Vikings, covered what geographical area?
Answer: London to Chester

Context and question: There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the -hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts -halo-esters and aldehydes to -hydroxy-esters, the SimmonsSmith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:
What is the zinc equivalent of the Grinard reaction?
Answer:
The Barbier reaction
