Here is a question about this article: In India the majority of these schools follow the Hanafi school of thought. The religious establishment forms part of the mainly two large divisions within the country, namely the Deobandis, who dominate in numbers (of whom the Darul Uloom Deoband constitutes one of the biggest madaris) and the Barelvis, who also make up a sizeable portion (Sufi-oriented). Some notable establishments include: Al Jamiatul Ashrafia, Mubarakpur, Manzar Islam Bareilly, Jamia Nizamdina New Delhi, Jamia Nayeemia Muradabad which is one of the largest learning centres for the Barelvis. The HR[clarification needed] ministry of the government of India has recently[when?] declared that a Central Madrasa Board would be set up. This will enhance the education system of madaris in India. Though the madaris impart Quranic education mainly, efforts are on to include Mathematics, Computers and science in the curriculum. In July 2015, the state government of Maharashtra created a stir de-recognised madrasa education, receiving critisicm from several political parties with the NCP accusing the ruling BJP of creating Hindu-Muslim friction in the state, and Kamal Farooqui of the All India Muslim Personal Law Board saying it was "ill-designed"
What is the answer to this question: What problems are arising due to the political conflicts over schools?

The problem: Answer a question about this article:
In 1899 the state legislature passed a new constitution, with requirements for poll taxes and literacy tests for voter registration which disfranchised most black Americans in the state. Exclusion from voting had wide effects: it meant that black Americans could not serve on juries or in any local office. After a decade of white supremacy, many people forgot that North Carolina had ever had thriving middle-class black Americans. Black citizens had no political voice in the state until after the federal Civil Rights Act of 1964 and Voting Rights Act of 1965 were passed to enforce their constitutional rights. It was not until 1992 that another African American was elected as a US Representative from North Carolina.
What year was the Federal Civil Rights Act?
****
The answer: 1964

Problem: Please answer a question about the following article about Elevator:
A elevator of this kind uses a vacuum on top of the cab and a valve on the top of the "shaft" to move the cab upwards and closes the valve in order to keep the cab at the same level. a diaphragm or a piston is used as a "brake" if there's a sudden increase in pressure avove the cab. however, to go down, it opens the valve so that the air can pressurize the top of the "shaft", allowing the cab to go down by its own weight. this also means that in case of a power failure, the cab will automatically go down. the "shaft" is made of acrilic, is always round, due to the shape of the vacuum pump turbine. in order to keep the air inside of the cab, rubber seals are used. due to technical limitations, these elevators have a low capacity. they usually allow 1-3 passengers and up to 525 lbs.
For sudden surges in pressure above the cab, what is used as a "brake"?
A: a diaphragm or a piston

Military settlement within the empire and at its borders broadened the context of Romanitas. Rome's citizen-soldiers set up altars to multiple deities, including their traditional gods, the Imperial genius and local deities sometimes with the usefully open-ended dedication to the diis deabusque omnibus (all the gods and goddesses). They also brought Roman "domestic" deities and cult practices with them. By the same token, the later granting of citizenship to provincials and their conscription into the legions brought their new cults into the Roman military.

What type of household gods and cults did soldiers bring to outer areas?
Answer: domestic

Until recently, in the absence of prior agreement on a clear and precise definition, the concept was thought to mean (as a shorthand) 'a division of sovereignty between two levels of government'. New research, however, argues that this cannot be correct, as dividing sovereignty - when this concept is properly understood in its core meaning of the final and absolute source of political authority in a political community - is not possible. The descent of the United States into Civil War in the mid-nineteenth century, over disputes about unallocated competences concerning slavery and ultimately the right of secession, showed this. One or other level of government could be sovereign to decide such matters, but not both simultaneously. Therefore, it is now suggested that federalism is more appropriately conceived as 'a division of the powers flowing from sovereignty between two levels of government'. What differentiates the concept from other multi-level political forms is the characteristic of equality of standing between the two levels of government established. This clarified definition opens the way to identifying two distinct federal forms, where before only one was known, based upon whether sovereignty resides in the whole (in one people) or in the parts (in many peoples): the federal state (or federation) and the federal union of states (or federal union), respectively. Leading examples of the federal state include the United States, Germany, Canada, Switzerland, Australia and India. The leading example of the federal union of states is the European Union.
What form of Federalism is characterized by where sovereignty resides in the whole?
federal state (or federation)
