Santa Monica is one of the most environmentally activist municipalities in the nation. The city first proposed its Sustainable City Plan in 1992 and in 1994, was one of the first cities in the nation to formally adopt a comprehensive sustainability plan, setting waste reduction and water conservation policies for both public and private sector through its Office of Sustainability and the Environment. Eighty-two percent of the city's public works vehicles now run on alternative fuels, including nearly 100% of the municipal bus system, making it among the largest such fleets in the country. Santa Monica fleet vehicles and Buses now source their natural gas from Redeem, a Southern California-based supplier of renewable and sustainable natural gas obtained from non-fracked methane biogas generated from organic landfill waste.
Water conservation policies have been adopted by what two sectors?
****
The answer: public and private

The problem: Answer a question about this article:
In the first year, 400 beer houses opened and within eight years there were 46,000 across the country, far outnumbering the combined total of long-established taverns, pubs, inns and hotels. Because it was so easy to obtain permission and the profits could be huge compared to the low cost of gaining permission, the number of beer houses was continuing to rise and in some towns nearly every other house in a street could be a beer house. Finally in 1869 the growth had to be checked by magisterial control and new licensing laws were introduced. Only then was it made harder to get a licence, and the licensing laws which operate today were formulated.
How many beer houses opened their doors in the inaugural year of the Beer Act?
****
The answer: 400

The problem: Answer a question about this article:
The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after Maruska left for Stanford, his RCA colleagues Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light. In 1974 the U.S. Patent Office awarded Maruska, Rhines and Stanford professor David Stevenson a patent for their work in 1972 (U.S. Patent US3819974 A) and today magnesium-doping of gallium nitride continues to be the basis for all commercial blue LEDs and laser diodes. These devices built in the early 1970s had too little light output to be of practical use and research into gallium nitride devices slowed. In August 1989, Cree introduced the first commercially available blue LED based on the indirect bandgap semiconductor, silicon carbide (SiC). SiC LEDs had very low efficiency, no more than about 0.03%, but did emit in the blue portion of the visible light spectrum.[citation needed]
When was the first blue-violet LED developed?
****
The answer: 1972

All military occupations were open to women in 1989, with the exception of submarine service, which opened in 2000. Throughout the 1990s, the introduction of women into the combat arms increased the potential recruiting pool by about 100 percent. It also provided opportunities for all persons to serve their country to the best of their abilities. Women were fully integrated in all occupations and roles by the government of Jean Chretien, and by 8 March 2000, even allowed to serve on submarines.
By how much did opening these jobs to women increase the recruiting pool by?
****
The answer:
100 percent
