Problem: Dissolution of the Soviet Union:

On October 17, 1987, about 3,000 Armenians demonstrated in Yerevan complaining about the condition of Lake Sevan, the Nairit chemicals plant, and the Metsamor Nuclear Power Plant, and air pollution in Yerevan. Police tried to prevent the protest but took no action to stop it once the march was underway. The demonstration was led by Armenian writers such as Silva Kaputikian, Zori Balayan, and Maro Margarian and leaders from the National Survival organization. The march originated at the Opera Plaza after speakers, mainly intellectuals, addressed the crowd.

The protesters were unhappy with the pollution in what body of water?

Problem: In 1997, the Vienna Philharmonic was "facing protests during a [US] tour" by the National Organization for Women and the International Alliance for Women in Music. Finally, "after being held up to increasing ridicule even in socially conservative Austria, members of the orchestra gathered [on 28 February 1997] in an extraordinary meeting on the eve of their departure and agreed to admit a woman, Anna Lelkes, as harpist." As of 2013, the orchestra has six female members; one of them, violinist Albena Danailova became one of the orchestra's concertmasters in 2008, the first woman to hold that position. In 2012, women still made up just 6% of the orchestra's membership. VPO president Clemens Hellsberg said the VPO now uses completely screened blind auditions.
In what year did the Vienna Philharmonic face protests in the US?

Answer: 1997


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Despite the calamity and huge death toll, Lisbon suffered no epidemics and within less than one year was already being rebuilt. The new city centre of Lisbon was designed to resist subsequent earthquakes. Architectural models were built for tests, and the effects of an earthquake were simulated by marching troops around the models. The buildings and big squares of the Pombaline City Centre still remain as one of Lisbon's tourist attractions. Sebastião de Melo also made an important contribution to the study of seismology by designing an inquiry that was sent to every parish in the country.
How did de Melo contribute to the study of seismology?
A: by designing an inquiry that was sent to every parish in the country


Context and question: Today, the system of Arabic and Islamic education has grown and further integrated with Kerala government administration. In 2005, an estimated 6,000 Muslim Arabic teachers taught in Kerala government schools, with over 500,000 Muslim students. State-appointed committees, not private mosques or religious scholars outside the government, determine the curriculum and accreditation of new schools and colleges. Primary education in Arabic and Islamic studies is available to Kerala Muslims almost entirely in after-school madrasa programs - sharply unlike full-time madaris common in north India, which may replace formal schooling. Arabic colleges (over eleven of which exist within the state-run University of Calicut and the Kannur University) provide B.A. and Masters' level degrees. At all levels, instruction is co-educational, with many women instructors and professors. Islamic education boards are independently run by the following organizations, accredited by the Kerala state government: Samastha Kerala Islamic Education Board, Kerala Nadvathul Mujahideen, Jamaat-e-Islami Hind, and Jamiat Ulema-e-Hind.
 What types of programs provide non-traditional Islamic teaching?
Answer: unanswerable


Question: The language of the Quran has been described as "rhymed prose" as it partakes of both poetry and prose; however, this description runs the risk of failing to convey the rhythmic quality of Quranic language, which is more poetic in some parts and more prose-like in others. Rhyme, while found throughout the Quran, is conspicuous in many of the earlier Meccan suras, in which relatively short verses throw the rhyming words into prominence. The effectiveness of such a form is evident for instance in Sura 81, and there can be no doubt that these passages impressed the conscience of the hearers. Frequently a change of rhyme from one set of verses to another signals a change in the subject of discussion. Later sections also preserve this form but the style is more expository.
Is there an answer to this question: What often changes along with the rhyming of Quranic verses?

Answer: subject of discussion


QUES: Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.

What type of boards end up with limited routing space in through-hole manufacture?
What is the answer?
ANS:
multi-layer
