On June 16, 1911, their four companies were consolidated in New York State by Charles Ranlett Flint to form the Computing-Tabulating-Recording Company (CTR). CTR's business office was in Endicott. The individual companies owned by CTR continued to operate using their established names until the businesses were integrated in 1933 and the holding company eliminated. The four companies had 1,300 employees and offices and plants in Endicott and Binghamton, New York; Dayton, Ohio; Detroit, Michigan; Washington, D.C.; and Toronto. They manufactured machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards.
In 1933 the four companies owned by CTR had how many employees?
****
The answer: 1,300 employees

In 2004, the first bike lane in the city was added to Orange Street, connecting East Rock Park and the East Rock neighborhood to downtown. Since then, bike lanes have also been added to sections of Howard Ave, Elm St, Dixwell Avenue, Water Street, Clinton Avenue and State Street. The city has created recommended bike routes for getting around New Haven, including use of the Canal Trail and the Orange Street lane. A bike map of the city entire can be seen here , and bike maps broken down by area here . As of the end of 2012, bicycle lanes have also been added in both directions on Dixwell Avenue along most of the street from downtown to the Hamden town line, as well as along Howard Avenue from Yale New Haven Hospital to City Point.
What year did New Haven finally integrated bike lanes to most of the city?
****
The answer: end of 2012


The problem: Answer a question about this article:
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 α-hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts α-halo-esters and aldehydes to β-hydroxy-esters, the Simmons–Smith 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 does organozinc chemisty describe?
****
The answer: physical properties, synthesis and reactions.


The problem: Answer a question about this article:
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
What bones in dog legs are fused?
****
The answer:
wrist
