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

Example Input: We describe the clinical characteristics and epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) in children with cystic fibrosis (CF) from the U.S. CF center with the highest MRSA prevalence. Medical records of children with CF were retrospectively reviewed from 1997-2009. MRSA clinical isolates from 2007-2009 were analyzed by polymerase chain reaction and pulsed field gel electrophoresis. The prevalence of MRSA was 1% in 1997 and 49% in 2009. Fifty-five children (26%) had persistent MRSA infection. Sixty-eight percent of MRSA isolates were hospital-associated (HA) MRSA, of which 52% were pulsed-field type USA 100. Ninety-three percent of HA MRSA isolates were clindamycin resistant. Twelve children acquired MRSA before 1 year of age, 83% of whom were hospitalized prior to acquisition of MRSA. Ten of 11 sibling pairs carried indistinguishable MRSA strains. Children with persistent MRSA were hospitalized more often (P=.01), required inhaled medications more frequently (P=.01), and had higher rates of Pseudomonas aeruginosa coinfection (P<.001). MRSA prevalence in children with CF is increasing, and most children are infected with HA MRSA. Exposure to health care facilities and gastrointestinal surgeries may facilitate early acquisition of MRSA. Siblings carry indistinguishable MRSA strains, indicating household transmission of MRSA. Children with persistent MRSA had worse pulmonary morbidity. Coinfection with MRSA and P aeruginosa is likely associated with further increased pulmonary morbidity.
Example Output: What is MRSA?

Example Input: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a small vessel disease of the brain caused by mutations in the NOTCH3 gene. CADASIL progresses, in some cases, to subcortical dementia with a particular cognitive impairment. Different diseases in the dementia spectrum share a central cholinergic and sensorimotor plasticity alteration. We aimed to study different intracortical circuits and sensorimotor plasticity in CADASIL patients using transcranial magnetic stimulation protocols, and to determine whether these characteristics correlated with the results of clinical neuropsychological evaluation. Ten CADASIL patients and 10 healthy subjects were included in the study. All subjects underwent a transcranial magnetic stimulation study examining different intracortical circuits. Sensorimotor plasticity was also assessed using a paired associative stimulation and extensive neuropsychological tests. CADASIL patients showed a lack of intracortical facilitation, short latency afferent inhibition and sensorimotor plasticity when compared with control subjects. CADASIL patients also showed an altered neuropsychological profile. Correlation between sensorimotor plasticity and neuropsychological alterations was observed in CADASIL patients. These results suggest that acetylcholine and glutamate could be involved in the dementia process in CADASIL and that abnormal sensorimotor plasticity correlates with the neuropsychological profile in CADASIL patients.
Example Output: Which gene is involved in CADASIL?
