Article: St. John's has traditionally been one of the safest cities in Canada to live; however, in recent years crime in the city has steadily increased. While nationally crime decreased by 4% in 2009, the total crime rate in St. John's saw an increase of 4%. During this same time violent crime in the city decreased 6%, compared to a 1% decrease nationally. In 2010 the total crime severity index for the city was 101.9, an increase of 10% from 2009 and 19.2% above the national average. The violent crime severity index was 90.1, an increase of 29% from 2009 and 1.2% above the national average. St. John's had the seventh-highest metropolitan crime index and twelfth-highest metropolitan violent crime index in the country in 2010.

Question: By how much did crime in St. John's increase in 2009?
Ans: 4%

Article: Chopin's mazurkas and waltzes are all in straightforward ternary or episodic form, sometimes with a coda. The mazurkas often show more folk features than many of his other works, sometimes including modal scales and harmonies and the use of drone basses. However, some also show unusual sophistication, for example Op. 63 No. 3, which includes a canon at one beat's distance, a great rarity in music.

Question: What type of bass do Chopin's mazurkas exhibit?
Ans: drone bass

Article: Under extreme compressive stresses and pressure, marine sedimentary rocks were uplifted, creating characteristic recumbent folds, or nappes, and thrust faults. As the rising peaks underwent erosion, a layer of marine flysch sediments was deposited in the foreland basin, and the sediments became involved in younger nappes (folds) as the orogeny progressed. Coarse sediments from the continual uplift and erosion were later deposited in foreland areas as molasse. The molasse regions in Switzerland and Bavaria were well-developed and saw further upthrusting of flysch.

Question: What were later deposited in foreland areas as molasse?
Ans: Coarse sediments

Article: During World War II, the development of the anti-aircraft proximity fuse required an electronic circuit that could withstand being fired from a gun, and could be produced in quantity. The Centralab Division of Globe Union submitted a proposal which met the requirements: a ceramic plate would be screenprinted with metallic paint for conductors and carbon material for resistors, with ceramic disc capacitors and subminiature vacuum tubes soldered in place. The technique proved viable, and the resulting patent on the process, which was classified by the U.S. Army, was assigned to Globe Union. It was not until 1984 that the Institute of Electrical and Electronics Engineers (IEEE) awarded Mr. Harry W. Rubinstein, the former head of Globe Union's Centralab Division, its coveted Cledo Brunetti Award for early key contributions to the development of printed components and conductors on a common insulating substrate. As well, Mr. Rubinstein was honored in 1984 by his alma mater, the University of Wisconsin-Madison, for his innovations in the technology of printed electronic circuits and the fabrication of capacitors.

Question: What was the plate used for anti-aircraft proximity fuses in World War II made out of?
Ans:
ceramic
