Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Example Input: CADASIL is a cerebrovascular disease caused by mutations in the NOTCH3 gene. Most mutations result in a gain or loss of cysteine residue in one of the 34 epidermal growth factor-like repeats in the extracellular domain of the Notch3 protein, thus sparing the number of cysteine residues. To date, more than 130 different mutations in the NOTCH3 gene have been reported in CADASIL patients, of which 95% are missense point mutations. Many polymorphisms have also been identified in the NOTCH3 coding sequence, some of them leading to amino acid substitutions. The aim of the present study was to analyze the NOTCH3 gene in a large group of patients affected by leukoencephalopathy and to investigate the presence of genetic variants. The molecular analysis revealed several nucleotide alterations. In particular, we identified 20 different mutations, 22 polymorphisms, and 8 genetic variants of unknown pathological significance never reported previously. We hope that this NOTCH3 gene mutational analysis, performed in such a significant number of unrelated and related patients affected by leukoencephalopathy, will help in molecular screening for the NOTCH3 gene, thus contributing to enlargement of the NOTCH3 gene variation database.
Example Output: Which amino acid residue appears mutated in most of the cases reported with  cadasil syndrome?

Example Input: In a few states where racial prejudice is serious, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are states where the white man imposes his rule by force; there are states where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence - as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more serious. The sheer horror, the bloodshed, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us. The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the shabby houses at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is weakened by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law. Before we can even begin to reflect on peaceful co-existence between the races, we must appreciate each other's problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. "Talk, talk, talk," the advocates of violence say, "all you ever do is talk, and we are none the wiser." It's rather like the story of the famous lawyer who carefully explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. "Possible, my lord," the lawyer replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.
