Input: Read this: All students and faculty, regardless of religion, are required to agree to adhere to an honor code. Early forms of the Church Educational System Honor Code are found as far back as the days of the Brigham Young Academy and early school President Karl G. Maeser. Maeser created the "Domestic Organization", which was a group of teachers who would visit students at their homes to see that they were following the schools moral rules prohibiting obscenity, profanity, smoking, and alcohol consumption. The Honor Code itself was not created until about 1940, and was used mainly for cases of cheating and academic dishonesty. President Wilkinson expanded the Honor Code in 1957 to include other school standards. This led to what the Honor Code represents today: rules regarding chastity, dress, grooming, drugs, and alcohol. A signed commitment to live the honor code is part of the application process, and must be adhered by all students, faculty, and staff. Students and faculty found in violation of standards are either warned or called to meet with representatives of the Honor Council. In certain cases, students and faculty can be expelled from the school or lose tenure. Both LDS and non-LDS students are required to meet annually with a Church leader to receive an ecclesiastical endorsement for both acceptance and continuance. Various LGBT advocacy groups have protested the honor code and criticized it as being anti-gay, and The Princeton Review ranked BYU as the 3rd most LGBT-unfriendly school in the United States.
Question: What did the Princeton Review rank BUY for LGBT-friendliness?

QUES: Fluids cannot generally be pulled, so a vacuum cannot be created by suction. Suction can spread and dilute a vacuum by letting a higher pressure push fluids into it, but the vacuum has to be created first before suction can occur. The easiest way to create an artificial vacuum is to expand the volume of a container. For example, the diaphragm muscle expands the chest cavity, which causes the volume of the lungs to increase. This expansion reduces the pressure and creates a partial vacuum, which is soon filled by air pushed in by atmospheric pressure.

What can be measured in the atmosphere?

QUES: 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]
What substance helped demonstrate the first blue electroluminescence?

ANS: zinc-doped gallium nitride

In recent years, Nanjing has been developing its economy, commerce, industry, as well as city construction. In 2013 the city's GDP was RMB 801 billion (3rd in Jiangsu), and GDP per capita(current price) was RMB 98,174(US$16041), a 11 percent increase from 2012. The average urban resident's disposable income was RMB 36,200, while the average rural resident's net income was RMB 14,513. The registered urban unemployment rate was 3.02 percent, lower than the national average (4.3 percent). Nanjing's Gross Domestic Product ranked 12th in 2013 in China, and its overall competence ranked 6th in mainland and 8th including Taiwan and Hong Kong in 2009.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How was Nanjing's unemployment rate, compared to the nation as a whole?
Ah, so.. lower than the national average

Question: In 1976 the future Labour prime minister James Callaghan launched what became known as the 'great debate' on the education system. He went on to list the areas he felt needed closest scrutiny: the case for a core curriculum, the validity and use of informal teaching methods, the role of school inspection and the future of the examination system. Comprehensive school remains the most common type of state secondary school in England, and the only type in Wales. They account for around 90% of pupils, or 64% if one does not count schools with low-level selection. This figure varies by region.
Try to answer this question if possible: What is the only kind of school operating in England?
Answer: unanswerable

Problem: Primarily starting in the mid-1960s, London became a centre for the worldwide youth culture, exemplified by the Swinging London subculture associated with the King's Road, Chelsea and Carnaby Street. The role of trendsetter was revived during the punk era. In 1965 London's political boundaries were expanded to take into account the growth of the urban area and a new Greater London Council was created. During The Troubles in Northern Ireland, London was subjected to bombing attacks by the Provisional IRA. Racial inequality was highlighted by the 1981 Brixton riot.
Why was the Greater London Council established?
---
Answer:
the growth of the urban area
