TASK DEFINITION: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
PROBLEM: Do you know of anyone who uses the truth to deceive ? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture. For example, some might say, "I just won a hundred dollars on the lottery . It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!" This guy's a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He's really a big loser! www. .com He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest. Some politicians often use this trick. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeked another term. One of her opponents said, "During Governor Smith's term, the state lost one million jobs!" That's true. However, an honest statement would have been, "During Governor Smith's term, the state had a net gain of two million jobs." Advertisers will sometimes use half-truths. It's against the law to make false statements so they try to mislead you with the truth. An advertisement might say, "Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache." It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company. This kind of deception happens too often. Lies are lies, and sometimes the truth can lie as well, which is a sad fact of life.

SOLUTION: How much did the lottery winner lose?

PROBLEM: Restless legs syndrome is a neurological disorder characterized by an urgency to move the legs during periods of rest. Data from a variety of sources provide a compelling argument that the amount of iron in the brain is lower in individuals with restless legs syndrome compared with neurologically normal individuals. Moreover, a significant percentage of patients with restless legs syndrome are responsive to intravenous iron therapy. The mechanism underlying the decreased iron concentrations in restless legs syndrome brains is unknown. We hypothesize that the source of the brain iron deficit is at the blood-brain interface. Thus we analysed the expression of iron management proteins in the epithelial cells of the choroid plexus and the brain microvasculature in post-mortem tissues. The choroid plexus, obtained at autopsy, from 18 neurologically normal controls and 14 individuals who had primary restless legs syndrome was subjected to histochemical staining for iron and immunostaining for iron management proteins. Iron and heavy chain ferritin staining was reduced in the epithelial cells of choroid plexus in restless legs syndrome. Divalent metal transporter, ferroportin, transferrin and its receptor were upregulated in the choroid plexus in restless legs syndrome. Microvessels were isolated from the motor cortex of 11 restless legs syndrome and 14 control brains obtained at autopsy and quantitative immunoblot analyses was performed. Expression of heavy chain ferritin, transferrin and its receptor in the microvessels from restless legs syndrome was significantly decreased compared with the controls but divalent metal protein 1, ferroportin, prohepcidin, mitochondrial ferritin and light-chain ferritin remained unchanged. The presence of an iron regulatory protein was demonstrated in the brain microvasculature and the activity of this protein is decreased in restless legs syndrome; a finding similar to our earlier report in neuromelanin cells from the substantia nigra of restless legs syndrome brains. This study reveals that there are alterations in the iron management protein profile in restless legs syndrome compared with controls at the site of blood-brain interface suggesting fundamental differences in brain iron acquisition in individuals with restless legs syndrome. Furthermore, the decrease in transferrin receptor expression in the microvasculature in the presence of relative brain iron deficiency reported in restless legs syndrome brains may underlie the problems associated with brain iron acquisition in restless legs syndrome. The consistent finding of loss of iron regulatory protein activity in restless legs syndrome brain tissue further implicates this protein as a factor in the underlying cause of the iron deficiency in the restless legs syndrome brain. The data herein provide evidence for regulation of iron uptake and storage within brain microvessels that challenge the existing paradigm that the blood-brain barrier is merely a transport system.

SOLUTION: Which deficiency is the cause of restless leg syndrome?

PROBLEM: Delta Chi () (del-ta kai) or D-Chi is an international Greek letter college social fraternity formed on October 13, 1890, at Cornell University, initially as a professional fraternity for law students.
