Problem: Education:

Research into LCPS (low cost private schools) found that over 5 years to July 2013, debate around LCPSs to achieving Education for All (EFA) objectives was polarised and finding growing coverage in international policy. The polarisation was due to disputes around whether the schools are affordable for the poor, reach disadvantaged groups, provide quality education, support or undermine equality, and are financially sustainable. The report examined the main challenges encountered by development organisations which support LCPSs. Surveys suggest these types of schools are expanding across Africa and Asia. This success is attributed to excess demand. These surveys found concern for:

Problem: Early house music was generally dance-based music characterized by repetitive 4/4 beats, rhythms mainly provided by drum machines, off-beat hi-hat cymbals, and synthesized basslines. While house displayed several characteristics similar to disco music, it was more electronic and minimalistic, and the repetitive rhythm of house was more important than the song itself. House music in the 2010s, while keeping several of these core elements, notably the prominent kick drum on every beat, varies widely in style and influence, ranging from the soulful and atmospheric deep house to the more minimalistic microhouse. House music has also fused with several other genres creating fusion subgenres, such as euro house, tech house, electro house and jump house.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).
How are today's database systems run?
A: general-purpose hardware

Context and question: The early currency of the United States did not exhibit faces of presidents, as is the custom now; although today, by law, only the portrait of a deceased individual may appear on United States currency. In fact, the newly formed government was against having portraits of leaders on the currency, a practice compared to the policies of European monarchs. The currency as we know it today did not get the faces they currently have until after the early 20th century; before that "heads" side of coinage used profile faces and striding, seated, and standing figures from Greek and Roman mythology and composite Native Americans. The last coins to be converted to profiles of historic Americans were the dime (1946) and the Dollar (1971).
When did modern day currency start getting the faces that they have?
Answer: 20th century

QUES: Since the Spanish transition to democracy (19751982), Catalan has been recognized as an official language, language of education, and language of mass media, all of which have contributed to its increased prestige. There is no parallel in Europe of such a large, bilingual, non-state speech community.

Where is there nothing like this non-state speech community?
