Article: For over 40 years, the FBI crime lab in Quantico believed lead in bullets had unique chemical signatures. It analyzed the bullets with the goal of matching them chemically, not only to a single batch of ammunition coming out of a factory, but also to a single box of bullets. The National Academy of Sciences conducted an 18-month independent review of comparative bullet-lead analysis. In 2003, its National Research Council published a report whose conclusions called into question 30 years of FBI testimony. It found the analytic model used by the FBI for interpreting results was deeply flawed, and the conclusion, that bullet fragments could be matched to a box of ammunition, was so overstated that it was misleading under the rules of evidence. One year later, the FBI decided to stop doing bullet lead analysis.

Question: How long was the National Academy of Sciences independent review?
Ans: 18-month


Article: Though known since antiquity the commercial growing of cotton in Egypt only started in 1820's, following a Frenchman, by the name of M. Jumel, propositioning the then ruler, Mohamed Ali Pasha, that he could earn a substantial income by growing an extra-long staple Maho (Barbadence) cotton, in Lower Egypt, for the French market. Mohamed Ali Pasha accepted the proposition and granted himself the monopoly on the sale and export of cotton in Egypt; and later dictated cotton should be grown in preference to other crops. By the time of the American Civil war annual exports had reached $16 million (120,000 bales), which rose to $56 million by 1864, primarily due to the loss of the Confederate supply on the world market. Exports continued to grow even after the reintroduction of US cotton, produced now by a paid workforce, and Egyptian exports reached 1.2 million bales a year by 1903.

Question: How many bales of cotton were produced by Egypt by 1903?
Ans: 1.2 million bales a year


Article: The radiation pattern and even the driving point impedance of an antenna can be influenced by the dielectric constant and especially conductivity of nearby objects. For a terrestrial antenna, the ground is usually one such object of importance. The antenna's height above the ground, as well as the electrical properties (permittivity and conductivity) of the ground, can then be important. Also, in the particular case of a monopole antenna, the ground (or an artificial ground plane) serves as the return connection for the antenna current thus having an additional effect, particularly on the impedance seen by the feed line.

Question: Whats another name for the ground?
Ans: artificial ground plane


Article: Arsenal Football Club was formed as Dial Square in 1886 by workers at the Royal Arsenal in Woolwich, south-east London, and were renamed Royal Arsenal shortly afterwards. The club was renamed again to Woolwich Arsenal after becoming a limited company in 1893. The club became the first southern member of the Football League in 1893, starting out in the Second Division, and won promotion to the First Division in 1904. The club's relative geographic isolation resulted in lower attendances than those of other clubs, which led to the club becoming mired in financial problems and effectively bankrupt by 1910, when they were taken over by businessmen Henry Norris and William Hall. Norris sought to move the club elsewhere, and in 1913, soon after relegation back to the Second Division, Arsenal moved to the new Arsenal Stadium in Highbury, north London; they dropped "Woolwich" from their name the following year. Arsenal only finished in fifth place in the second division during the last pre-war competitive season of 1914–15, but were nevertheless elected to rejoin the First Division when competitive football resumed in 1919–20, at the expense of local rivals Tottenham Hotspur. Some books have reported that this election to division 1 was achieved by dubious means.

Question: In which division was Arsenal ranked by the start of WWI?
Ans:
second division
