Problem: Asphalt:

The first British patent for the use of asphalt/bitumen was 'Cassell's patent asphalte or bitumen' in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.

The second patent, Cassell's patent, was issued in which year?

Problem: Sir John Call argued the advantages of Norfolk Island in that it was uninhabited and that New Zealand flax grew there. In 1786 the British government included Norfolk Island as an auxiliary settlement, as proposed by John Call, in its plan for colonisation of New South Wales. The decision to settle Norfolk Island was taken due to Empress Catherine II of Russia's decision to restrict sales of hemp. Practically all the hemp and flax required by the Royal Navy for cordage and sailcloth was imported from Russia.
Where was the majority of the hemp and flax used by the Royal Navy imported from?
---
Answer: Russia


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
This position was carried by the D.C. Statehood Party, a political party; it has since merged with the local Green Party affiliate to form the D.C. Statehood Green Party. The nearest this movement ever came to success was in 1978, when Congress passed the District of Columbia Voting Rights Amendment. Two years later in 1980, local citizens passed an initiative calling for a constitutional convention for a new state. In 1982, voters ratified the constitution of the state, which was to be called New Columbia. The drive for statehood stalled in 1985, however, when the Washington, D.C. Voting Rights Amendment failed because not enough states ratified the amendment within the seven-year span specified.
When did the drive for Columbian statehood falter?
A: unanswerable


Context and question: Saint Barthélemy was for many years a French commune forming part of Guadeloupe, which is an overseas region and department of France. Through a referendum in 2003, island residents sought separation from the administrative jurisdiction of Guadeloupe, and it was finally accomplished in 2007. The island of Saint Barthélemy became an Overseas Collectivity (COM). A governing territorial council was elected for its administration, which has provided the island with a certain degree of autonomy. The Hotel de Ville, which was the town hall, is now the Hotel de la Collectivité. A senator represents the island in Paris. St. Barthélemy has retained its free port status.
Who officially represents St. Barts in French legislation? 
Answer: A senator


Question: It is a fully developed legal system, with all the necessary elements: courts, lawyers, judges, a fully articulated legal code principles of legal interpretation, and coercive penalties, though it lacks civilly-binding force in most secular jurisdictions. The academic degrees in canon law are the J.C.B. (Juris Canonici Baccalaureatus, Bachelor of Canon Law, normally taken as a graduate degree), J.C.L. (Juris Canonici Licentiatus, Licentiate of Canon Law) and the J.C.D. (Juris Canonici Doctor, Doctor of Canon Law). Because of its specialized nature, advanced degrees in civil law or theology are normal prerequisites for the study of canon law.
Is there an answer to this question: What profesional roles from secular law does the Catholic Church also employ?

Answer: lawyers, judges


QUES: Gram quantities of various copper salts have been taken in suicide attempts and produced acute copper toxicity in humans, possibly due to redox cycling and the generation of reactive oxygen species that damage DNA. Corresponding amounts of copper salts (30 mg/kg) are toxic in animals. A minimum dietary value for healthy growth in rabbits has been reported to be at least 3 ppm in the diet. However, higher concentrations of copper (100 ppm, 200 ppm, or 500 ppm) in the diet of rabbits may favorably influence feed conversion efficiency, growth rates, and carcass dressing percentages.

What amount of copper salt is toxic in robots?
