This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

[EX Q]: The limited standardization of analog HDTV in the 1990s did not lead to global HDTV adoption as technical and economic constraints at the time did not permit HDTV to use bandwidths greater than normal television.
[EX A]: What constraints kept HDTV from being widely adopted in the 90's?

[EX Q]: "Funday Night at the Movies" was replaced in 2008 by "Essentials Jr.", a youth-oriented version of its weekly series The Essentials (originally hosted by actors Abigail Breslin and Chris O'Donnell, then by John Lithgow from 2009 to 2011, and then by Bill Hader starting with the 2011 season), which included such family-themed films as National Velvet, Captains Courageous and Yours, Mine and Ours, as well as more eclectic selections as Sherlock, Jr., The Music Box, Harvey, Mutiny on the Bounty and The Man Who Knew Too Much.
[EX A]: What series replaced Funday Night at the Movies?

[EX Q]: Normal functioning of the kidney, brain, liver, heart, and other systems can be affected by uranium exposure, because, besides being weakly radioactive, uranium is a toxic metal. Uranium is also a reproductive toxicant. Radiological effects are generally local because alpha radiation, the primary form of 238U decay, has a very short range, and will not penetrate skin. Uranyl (UO2+
2) ions, such as from uranium trioxide or uranyl nitrate and other hexavalent uranium compounds, have been shown to cause birth defects and immune system damage in laboratory animals. While the CDC has published one study that no human cancer has been seen as a result of exposure to natural or depleted uranium, exposure to uranium and its decay products, especially radon, are widely known and significant health threats. Exposure to strontium-90, iodine-131, and other fission products is unrelated to uranium exposure, but may result from medical procedures or exposure to spent reactor fuel or fallout from nuclear weapons. Although accidental inhalation exposure to a high concentration of uranium hexafluoride has resulted in human fatalities, those deaths were associated with the generation of highly toxic hydrofluoric acid and uranyl fluoride rather than with uranium itself. Finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature.
[EX A]:
Along with the heart, brain and liver, what system is notably affected by exposure to uranium?
