The city struck fortune in the late 18th century with the inventions and industrial activity of Eli Whitney, a Yale graduate who remained in New Haven to develop the cotton gin and establish a gun-manufacturing factory in the northern part of the city near the Hamden town line. That area is still known as Whitneyville, and the main road through both towns is known as Whitney Avenue. The factory is now the Eli Whitney Museum, which has a particular emphasis on activities for children and exhibits pertaining to the A. C. Gilbert Company. His factory, along with that of Simeon North, and the lively clock-making and brass hardware sectors, contributed to making early Connecticut a powerful manufacturing economy; so many arms manufacturers sprang up that the state became known as "The Arsenal of America". It was in Whitney's gun-manufacturing plant that Samuel Colt invented the automatic revolver in 1836. The Farmington Canal, created in the early 19th century, was a short-lived transporter of goods into the interior regions of Connecticut and Massachusetts, and ran from New Haven to Northampton, Massachusetts.
In 1836, who invented the automatic revolver in Eli Whitney's gun manufacturing plant?
A: Samuel Colt

Beyoncé and her mother introduced House of Deréon, a contemporary women's fashion line, in 2005. The concept is inspired by three generations of women in their family, the name paying tribute to Beyoncé's grandmother, Agnèz Deréon, a respected seamstress. According to Tina, the overall style of the line best reflects her and Beyoncé's taste and style. Beyoncé and her mother founded their family's company Beyond Productions, which provides the licensing and brand management for House of Deréon, and its junior collection, Deréon. House of Deréon pieces were exhibited in Destiny's Child's shows and tours, during their Destiny Fulfilled era. The collection features sportswear, denim offerings with fur, outerwear and accessories that include handbags and footwear, and are available at department and specialty stores across the US and Canada.
Who was the business named for in Beyonce's family?
A: grandmother, Agnèz Deréon

In 2007 Torsten Struck and colleagues compared 3 genes in 81 taxa, of which 9 were outgroups, in other words not considered closely related to annelids but included to give an indication of where the organisms under study are placed on the larger tree of life. For a cross-check the study used an analysis of 11 genes (including the original 3) in 10 taxa. This analysis agreed that clitellates, pogonophorans and echiurans were on various branches of the polychaete family tree. It also concluded that the classification of polychaetes into Scolecida, Canalipalpata and Aciculata was useless, as the members of these alleged groups were scattered all over the family tree derived from comparing the 81 taxa. In addition, it also placed sipunculans, generally regarded at the time as a separate phylum, on another branch of the polychaete tree, and concluded that leeches were a sub-group of oligochaetes rather than their sister-group among the clitellates. Rouse accepted the analyses based on molecular phylogenetics, and their main conclusions are now the scientific consensus, although the details of the annelid family tree remain uncertain.
What subtypes of polychaetes were useless classifications, according to the 1997 study?
A: unanswerable

Luftwaffe policy at this point was primarily to continue progressive attacks on London, chiefly by night attack; second, to interfere with production in the vast industrial arms factories of the West Midlands, again chiefly by night attack; and third to disrupt plants and factories during the day by means of fighter-bombers. Kesselring, commanding Luftflotte 2, was ordered to send 50 sorties per night against London and attack eastern harbours in daylight. Sperrle, commanding Luftflotte 3, was ordered to dispatch 250 sorties per night including 100 against the West Midlands. Seeschlange would be carried out by Fliegerkorps X (10th Air Corps) which concentrated on mining operations against shipping. It also took part in the bombing over Britain. By 19/20 April 1941, it had dropped 3,984 mines, ⅓ of the total dropped. The mines' ability to destroy entire streets earned them respect in Britain, but several fell unexploded into British hands allowing counter-measures to be developed which damaged the German anti-shipping campaign.
What did the Fliegerkorps X concentrate on?
A:
mining operations against shipping
