Problem: Comprehensive school:

The largest expansion of comprehensive schools in 1965 resulted from a policy decision taken in 1965 by Anthony Crosland, Secretary of State for Education in the 19641970 Labour government. The policy decision was implemented by Circular 10/65, an instruction to local education authorities to plan for conversion. Students sat the 11+ examination in their last year of primary education and were sent to one of a secondary modern, secondary technical or grammar school depending on their perceived ability. Secondary technical schools were never widely implemented and for 20 years there was a virtual bipartite system which saw fierce competition for the available grammar school places, which varied between 15% and 25% of total secondary places, depending on location.[citation needed]

Problem: where is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/2 = 12.7% of saturation. The factor 2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.
What does the sensor usually determine?

Answer: lower limit of the saturation speed

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Athanasius's episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed the aged Alexander. That council also denounced various heresies and schisms, many of which continued to preoccupy his 45-year-long episcopate (c. 8 June 328 2 May 373). Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life. This gave rise to the expression "Athanasius contra mundum" or "Athanasius against the world". However, during his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya. He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years. Shortly thereafter, Athanasius became occupied with the theological disputes against Arians within the Byzantine Empire that would occupy much of his life.
Who did Athanasius proceed?
A: unanswerable

Context and question: In the greater metropolitan area, 13% of the population live below the poverty line. According to a 2012 report submitted by GHMC to the World Bank, Hyderabad has 1,476 slums with a total population of 1.7 million, of whom 66% live in 985 slums in the "core" of the city (the part that formed Hyderabad before the April 2007 expansion) and the remaining 34% live in 491 suburban tenements. About 22% of the slum-dwelling households had migrated from different parts of India in the last decade of the 20th century, and 63% claimed to have lived in the slums for more than 10 years.:55 Overall literacy in the slums is 6080% and female literacy is 5273%. A third of the slums have basic service connections, and the remainder depend on general public services provided by the government. There are 405 government schools, 267 government aided schools, 175 private schools and 528 community halls in the slum areas.:70 According to a 2008 survey by the Centre for Good Governance, 87.6% of the slum-dwelling households are nuclear families, 18% are very poor, with an income up to 20000 (US$300) per annum, 73% live below the poverty line (a standard poverty line recognised by the Andhra Pradesh Government is 24000 (US$360) per annum), 27% of the chief wage earners (CWE) are casual labour and 38% of the CWE are illiterate. About 3.72% of the slum children aged 514 do not go to school and 3.17% work as child labour, of whom 64% are boys and 36% are girls. The largest employers of child labour are street shops and construction sites. Among the working children, 35% are engaged in hazardous jobs.:59
What percentage of children in Hyderabad are working hazardous jobs?
Answer: 35%

Question: The first six presidents of the United States did not make extensive use of the veto power: George Washington only vetoed two bills, James Monroe one, and John Adams, Thomas Jefferson and John Quincy Adams none. James Madison, a firm believer in a strong executive, vetoed seven bills. None of the first six Presidents, however, used the veto to direct national policy. It was Andrew Jackson, the seventh President, who was the first to use the veto as a political weapon. During his two terms in office, he vetoed twelve billsmore than all of his predecessors combined. Furthermore, he defied the Supreme Court in enforcing the policy of ethnically cleansing Native American tribes ("Indian Removal"); he stated (perhaps apocryphally), "John Marshall has made his decision. Now let him enforce it!"
Is there an answer to this question: How many bills did George Washington veto?

Answer: two

The final son of Abd al-Malik to become caliph was Hisham (72443), whose long and eventful reign was above all marked by the curtailment of military expansion. Hisham established his court at Resafa in northern Syria, which was closer to the Byzantine border than Damascus, and resumed hostilities against the Byzantines, which had lapsed following the failure of the last siege of Constantinople. The new campaigns resulted in a number of successful raids into Anatolia, but also in a major defeat (the Battle of Akroinon), and did not lead to any significant territorial expansion.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Hisham's reign start?
Ah, so..
