Question: The world's oldest football competition is the FA Cup, which was founded by C. W. Alcock and has been contested by English teams since 1872. The first official international football match also took place in 1872, between Scotland and England in Glasgow, again at the instigation of C. W. Alcock. England is also home to the world's first football league, which was founded in Birmingham in 1888 by Aston Villa director William McGregor. The original format contained 12 clubs from the Midlands and Northern England.
Try to answer this question if possible: How many clubs were in the last football league?
Answer: unanswerable
Question: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.

Question: To create green sparks, fireworks use barium salts, such as barium chlorate, barium nitrate crystals, or barium chloride, also used for green fireplace logs. Copper salts typically burn blue, but cupric chloride (also known as "campfire blue") can also produce green flames. Green pyrotechnic flares can use a mix ratio 75:25 of boron and potassium nitrate. Smoke can be turned green by a mixture: solvent yellow 33, solvent green 3, lactose, magnesium carbonate plus sodium carbonate added to potassium chlorate.
Try to answer this question if possible: Which two solvents are used in green pyrotechnic flares?
Answer: unanswerable
Question: Experts point out that the earthquake hit an area that has been largely neglected and untouched by China's economic rise. Health care is poor in inland areas such as Sichuan, highlighting the widening gap between prosperous urban dwellers and struggling rural people. Vice Minister of Health Gao Qiang told reporters in Beijing that the "public health care system in China is insufficient." The Vice Minister of Health also suggested that the government would pick up the costs of care to earthquake victims, many of whom have little or no insurance: "The government should be responsible for providing medical treatment to them," he said.
Try to answer this question if possible: What did the Vice Minster of Health call the public health system in China?
Answer:
insufficient
