Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Input: Consider Input: Context: 51827 Laurelclark (2001 OH38) is an asteroid named for astronaut Laurel Clark, who was killed in the STS-107 (Columbia) space shuttle reentry disaster on February 1, 2003. 
 Question: Whom is 51827 Laurelclark named after?

Output: laurel clark


Input: Consider Input: Context: In the present study, we tested the hypothesis that having migraine in middle age is related to late-life parkinsonism and a related disorder, restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED). The AGES-Reykjavik cohort (born 1907-1935) has been followed since 1967. Headaches were classified based on symptoms assessed in middle age. From 2002 to 2006, 5,764 participants were reexamined to assess symptoms of parkinsonism, diagnosis of Parkinson disease (PD), family history of PD, and RLS/WED. Subjects with midlife migraine, particularly migraine with aura (MA), were in later life more likely than others to report parkinsonian symptoms (odds ratio [OR]MA = 3.6 [95% CI 2.7-4.8]) and diagnosed PD (ORMA = 2.5 [95% CI 1.2-5.2]). Women with MA were more likely than others to have a parent (ORMA = 2.26 [95% CI 1.3-4.0]) or sibling (ORMA = 1.78 [95% CI 1.1-2.9]) with PD. Late-life RLS/WED was increased for headache generally. Associations were independent of cardiovascular disease and MRI-evident presumed ischemic lesions. These findings suggest there may be a common vulnerability to, or consequences of, migraine and multiple indicators of parkinsonism. Additional genetic and longitudinal observational studies are needed to identify candidate pathways that may account for the comorbid constellation of symptoms. 
 Question: Willis-Ekbom disease is also known as?

Output: restless legs syndrome


Input: Consider Input: Context: Acrokeratosis paraneoplastica (Bazex' syndrome) is a rare but clinically distinctive dermatosis that has been associated in all reported cases, to our knowledge, with either a primary malignant neoplasm of the upper aerodigestive tract or metastatic cancer to the lymph nodes of the neck. Acrokeratosis paraneoplastica was found in a 53-year-old black man with squamous cell carcinoma of the tonsil. A distinctive series of changes was found on histopathologic examination of biopsy specimens taken from his skin lesions, and direct immunofluorescence microscopy of both lesional and nonlesional skin specimens showed immunoglobulin and complement deposition on the epidermal basement membrane. The skin lesions largely resolved following radiation therapy of the neoplasm and of the presumably involved lymph nodes. 
 Question: Name synonym of Acrokeratosis paraneoplastica.


Output: bazex syndrome
