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.

Example Input: Context: Lever House, designed by Gordon Bunshaft and Natalie de Blois (design coordinator) of Skidmore, Owings and Merrill and located at 390 Park Avenue in Midtown Manhattan, New York City, is a seminal glass-box skyscraper built in the International Style according to the design principles of Ludwig Mies van der Rohe. 
 Question: Who was the architect or designer of Lever House?
Example Output: gordon bunshaft

Example Input: Context: Christianson syndrome (CS) is an X-linked neurodevelopmental and neurological disorder characterized in males by core symptoms that include non-verbal status, intellectual disability, epilepsy, truncal ataxia, postnatal microcephaly and hyperkinesis. CS is caused by mutations in the SLC9A6 gene, which encodes a multipass transmembrane sodium (potassium)-hydrogen exchanger 6 (NHE6) protein, functional in early recycling endosomes. The extent and variability of the CS phenotype in female heterozygotes, who presumably express the wild-type and mutant SLC9A6 alleles mosaically as a result of X-chromosome inactivation (XCI), have not yet been systematically characterized. Slc9a6 knockout mice (Slc9a6 KO) were generated by insertion of the bacterial lacZ/-galactosidase (-Gal) reporter into exon 6 of the X-linked gene. Mutant Slc9a6 KO male mice have been shown to develop late endosomal/lysosomal dysfunction associated with glycolipid accumulation in selected neuronal populations and patterned degeneration of Purkinje cells (PCs). In heterozygous female Slc9a6 KO mice, -Gal serves as a transcriptional/XCI reporter and thus facilitates testing of effects of mosaic expression of the mutant allele on penetrance of the abnormal phenotype. Using -Gal, we demonstrated mosaic expression of the mutant Slc9a6 allele and mosaically distributed lysosomal glycolipid accumulation and PC pathology in the brains of heterozygous Slc9a6 KO female mice. At the behavioral level, we showed that heterozygous female mice suffer from visuospatial memory and motor coordination deficits similar to but less severe than those observed in X-chromosome hemizygous mutant males. Our studies in heterozygous Slc9a6 KO female mice provide important clues for understanding the likely phenotypic range of Christianson syndrome among females heterozygous for SLC9A6 mutations and might improve diagnostic practice and genetic counseling by helping to characterize this presumably underappreciated patient/carrier group. 
 Question: Mutation of which gene is implicated in the Christianson syndrome?
Example Output: slc9a6

Example Input: Context: Coming off their bye week, the Jets stayed at home for a Week 10 duel with the Jacksonville Jaguars. New York would trail early in the first quarter with running back Maurice Jones-Drew's 33-yard touchdown run. The Jets would respond with kicker Jay Feely getting a 32-yard field goal, followed by rookie quarterback Mark Sanchez completing a 7-yard touchdown pass to wide receiver Jerricho Cotchery. In the second quarter, Jacksonville would take the lead as quarterback David Garrard got an 11-yard touchdown run and completed a 26-yard touchdown pass to wide receiver Mike Sims-Walker. New York would close out the half as Feely made a 37-yard field goal. After a scoreless third quarter, the Jets would regain the lead in the fourth quarter with a 40-yard field goal from Feely and a 1-yard touchdown run from running back Thomas Jones (with a failed 2-point conversion). However, the Jaguars got the last laugh as kicker Josh Scobee booted the game-winning 21-yard field goal. 
 Question: Who kicked the longest field goal?
Example Output:
feely
