Article: Like most of southern California, the majority of San Diego's current area was originally occupied by chaparral, a plant community made up mostly of drought-resistant shrubs. The endangered Torrey pine has the bulk of its population in San Diego in a stretch of protected chaparral along the coast. The steep and varied topography and proximity to the ocean create a number of different habitats within the city limits, including tidal marsh and canyons. The chaparral and coastal sage scrub habitats in low elevations along the coast are prone to wildfire, and the rates of fire have increased in the 20th century, due primarily to fires starting near the borders of urban and wild areas.

Question: Where can one find the most sage scrub in San Diego?
Ans: low elevations


Article: Edwin Chadwick's 1829 article, "Preventive police" in the London Review, argued that prevention ought to be the primary concern of a police body, which was not the case in practice. The reason, argued Chadwick, was that "A preventive police would act more immediately by placing difficulties in obtaining the objects of temptation." In contrast to a deterrent of punishment, a preventive police force would deter criminality by making crime cost-ineffective - "crime doesn't pay". In the second draft of his 1829 Police Act, the "object" of the new Metropolitan Police, was changed by Robert Peel to the "principal object," which was the "prevention of crime." Later historians would attribute the perception of England's "appearance of orderliness and love of public order" to the preventive principle entrenched in Peel's police system.

Question: Where was 'Preventive Police' published?
Ans: London Review


Article: The disquilibrium and perceived corruption of the electoral and political process led, in 1966, to back-to-back military coups. The first coup was in January 1966 and was led by Igbo soldiers under Majors Emmanuel Ifeajuna and Chukwuma Kaduna Nzeogwu. The coup plotters succeeded in murdering Prime Minister Abubakar Tafawa Balewa, Premier Ahmadu Bello of the Northern Region and Premier Ladoke Akintola of the Western Region. But, the coup plotters struggled to form a central government. President Nwafor Orizu handed over government control to the Army, then under the command of another Igbo officer, General JTU Aguiyi-Ironsi.

Question: In what year were there two military coups in Nigeria?
Ans: 1966


Article: The "photoelectrons" emitted as a result of the photoelectric effect have a certain kinetic energy, which can be measured. This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect)  Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy.

Question: If the photoelectric effect is occuring, increasing the intensity of the light source causes what?
Ans:
more photoelectrons to be emitted with the same kinetic energy
