Problem: Please answer a question about the following article about Film speed:
Film speed is found from a plot of optical density vs. log of exposure for the film, known as the Dlog H curve or HurterDriffield curve. There typically are five regions in the curve: the base + fog, the toe, the linear region, the shoulder, and the overexposed region. For black-and-white negative film, the "speed point" m is the point on the curve where density exceeds the base + fog density by 0.1 when the negative is developed so that a point n where the log of exposure is 1.3 units greater than the exposure at point m has a density 0.8 greater than the density at point m. The exposure Hm, in lux-s, is that for point m when the specified contrast condition is satisfied. The ISO arithmetic speed is determined from:
What is plotted in the Hurter-Driffield curve?
A: a plot of optical density vs. log of exposure for the film
Problem: Please answer a question about the following article about Frederic Chopin:
Chopin's relations with Sand were soured in 1846 by problems involving her daughter Solange and Solange's fiance, the young fortune-hunting sculptor Auguste Clesinger. The composer frequently took Solange's side in quarrels with her mother; he also faced jealousy from Sand's son Maurice. Chopin was utterly indifferent to Sand's radical political pursuits, while Sand looked on his society friends with disdain. As the composer's illness progressed, Sand had become less of a lover and more of a nurse to Chopin, whom she called her "third child". In letters to third parties, she vented her impatience, referring to him as a "child," a "little angel", a "sufferer" and a "beloved little corpse." In 1847 Sand published her novel Lucrezia Floriani, whose main charactersa rich actress and a prince in weak healthcould be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys. In 1847 he did not visit Nohant, and he quietly ended their ten-year relationship following an angry correspondence which, in Sand's words, made "a strange conclusion to nine years of exclusive friendship." The two would never meet again.
What role did Sand take on as her relationship with Chopin progressed?
A: nurse
Problem: Please answer a question about the following article about BBC Television:
National and regional variations also occur within the BBC One and BBC Two schedules. England's BBC One output is split up into fifteen regions (such as South West and East), which exist mainly to produce local news programming, but also occasionally opt out of the network to show programmes of local importance (such as major local events). The other nations of the United Kingdom (Wales, Scotland and Northern Ireland) have been granted more autonomy from the English network; for example, programmes are mostly introduced by local announcers, rather than by those in London. BBC One and BBC Two schedules in the other UK nations can vary immensely from BBC One and BBC Two in England.
What kind of coverage might take precedence over standard BBC programming?
A: major local events
Problem: Please answer a question about the following article about Melbourne:
Water storage and supply for Melbourne is managed by Melbourne Water, which is owned by the Victorian Government. The organisation is also responsible for management of sewerage and the major water catchments in the region as well as the Wonthaggi desalination plant and NorthSouth Pipeline. Water is stored in a series of reservoirs located within and outside the Greater Melbourne area. The largest dam, the Thomson River Dam, located in the Victorian Alps, is capable of holding around 60% of Melbourne's water capacity, while smaller dams such as the Upper Yarra Dam, Yan Yean Reservoir, and the Cardinia Reservoir carry secondary supplies.
Which is Melbourne's largest dam?
A:
Thomson River Dam
