Problem: Film speed:

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 can too much exposure lead to?
---
A: clipped or bloomed camera output


Problem: The city is also the home of road bowling, which is played in the north-side and south-west suburbs. There are also boxing and martial arts clubs (including Brazilian jiu-jitsu, Karate, Muay Thai and Taekwondo) within the city. Cork Racing, a motorsport team based in Cork, has raced in the Irish Formula Ford Championship since 2005. Cork also hosts one of Ireland's most successful Australian Rules Football teams, the Leeside Lions, who have won the Australian Rules Football League of Ireland Premiership four times (in 2002, 2003, 2005 and 2007). There are also inline roller sports, such as hockey and figure skating, which transfer to the ice over the winter season.[citation needed]
During what season is road bowling played inside?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In absolute terms, the planet has lost 52% of its biodiversity since 1970 according to a 2014 study by the World Wildlife Fund. The Living Planet Report 2014 claims that "the number of mammals, birds, reptiles, amphibians and fish across the globe is, on average, about half the size it was 40 years ago". Of that number, 39% accounts for the terrestrial wildlife gone, 39% for the marine wildlife gone, and 76% for the freshwater wildlife gone. Biodiversity took the biggest hit in Latin America, plummeting 83 percent. High-income countries showed a 10% increase in biodiversity, which was canceled out by a loss in low-income countries. This is despite the fact that high-income countries use five times the ecological resources of low-income countries, which was explained as a result of process whereby wealthy nations are outsourcing resource depletion to poorer nations, which are suffering the greatest ecosystem losses.
What percentage of biodiversity has the planet lost since 2014?
A: unanswerable


Context and question: A striking technical innovation of the Komnenian period was the production of very precious, miniature mosaic icons. In these icons the small tesserae (with sides of 1 mm or less) were set on wax or resin on a wooden panel. These products of extraordinary craftmanship were intended for private devotion. The Louvre Transfiguration is a very fine example from the late 12th century. The miniature mosaic of Christ in the Museo Nazionale at Florence illustrates the more gentle, humanistic conception of Christ which appeared in the 12th century.
The more humanistic conception of Christ appeared when?
Answer: in the 12th century


Question: Sassou Nguesso aligned the country with the Eastern Bloc and signed a twenty-year friendship pact with the Soviet Union. Over the years, Sassou had to rely more on political repression and less on patronage to maintain his dictatorship.

Four boarders at his parents' apartments became Chopin's intimates: Tytus Woyciechowski, Jan Nepomucen Białobłocki, Jan Matuszyński and Julian Fontana; the latter two would become part of his Paris milieu. He was friendly with members of Warsaw's young artistic and intellectual world, including Fontana, Józef Bohdan Zaleski and Stefan Witwicki. He was also attracted to the singing student Konstancja Gładkowska. In letters to Woyciechowski, he indicated which of his works, and even which of their passages, were influenced by his fascination with her; his letter of 15 May 1830 revealed that the slow movement (Larghetto) of his Piano Concerto No. 1 (in E minor) was secretly dedicated to her – "It should be like dreaming in beautiful springtime – by moonlight." His final Conservatory report (July 1829) read: "Chopin F., third-year student, exceptional talent, musical genius."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Chopin receive his last Conservatory report?
Ah, so..
July 1829
