Input: Consider Input: Context: In 2009, 78.5% of Dallas (city) commuters drive to work alone. The 2009 modal share for Dallas (city) commuters are 10.7% for carpooling, 3.9% for transit, 1.9% for walking, and .1% for cycling. In 2015, the American Community Survey estimated modal shares for Dallas (city) commuters of 75.4% for driving alone, 12.8% for carpooling, 3.5% for riding transit, 1.9% for walking, and .2% for cycling. The city of Dallas has a higher than average percentage of households without a car. In 2015, 10.2 percent of Dallas households lacked a car, and decreased to 9.1 percent in 2016. The national average was 8.7 percent in 2016. Dallas averaged 1.59 cars per household in 2016, compared to a national average of 1.8. 
 Question: Which group in percent of commuters in Dallas in 2009 is larger: carpooling or walking?

Output: carpooling


Input: Consider Input: Context: The company "Spacely Sprockets and Spindles" is in dire trouble. Their latest project, dubbed the 'Orbiting Ore Asteroid,' has had numerous technical setbacks, doing only 3 days of work in over 6 months. To make matters worse, the vice-president in charge of operations, Alexander Throttle-bottom, has run off, making this the fourth vice-president that the operation has lost. Matters are further compounded when the site's assistant refuses to press the start button to activate the factory, or accept Spacely's offer for a promotion or raise.Using his secretarial computer, Spacely pegs George Jetson to be the new vice-president, sending George home to pack and tell his family. However, the news is met with with sadness, as the move will interfere with Jane's recycling program, Elroy's spaceball tournament, and Judy's date with rock star Cosmic Cosmo.Even so, the family manages to come together (with the exception of Judy who is sad about her missed date), and the family arrives at the 'Orbiting Ore Asteroid,' which not only houses the factory, but a shopping center and housing complex. The Jetsons meet their new neighbors, including Lucy-2, whose husband Rudy-2 works at the factory, and son Teddy-2 plays on the local spaceball team. They also meet the Furbolo family, including their mischievous daughter, Fergie.The next day, George arrives at work and meets Rudy-2. Rudy verses George on the factory equipment, and they prepare for the official start-up of the factory. Meanwhile, Jane and Judy go shopping with Lucy-2. Still feeling depressed, Judy goes off on her own, and meets a boy named Apollo Blue, whom she quickly develops a crush on.Later on that day, everyone turns out for the re-opening of the plant, with George activating the controls. However, the machine malfunctions again, irritating Spacely. Shortly thereafter, Rudy-2 reveals to George about previous technical issues with the plant, and cautions that it may be safer if George were to go home. George refuses, not wanting to give up on being vice-president. The next day, repairs appear to be made but the factory again malfunctions. Spacely blames George for the technical glitches, and leaves Earth to check on the factory.After inspecting the factory again, Rudy-2 reveals that the incidents do not appear to be accidents, but 'warnings' to shut down the plant. Rudy then explains about the factory's troubles, and of the 4 previous vice-presidents. George decides to stay overnight at the plant, and figure out just what is happening.Elroy and Teddy-2 sneak off to follow him. However, when their disappearance is found out, Jane asks Judy and Apollo Blue to try and find them. Judy and Apollo find both Elroy and Teddy-2 at the plant, along with Fergie, who tagged along. They also find a strange little creature, whose species Fergie identifies as a Grungee. The Grungee leads them into the core of the asteroid, where it is revealed why the factory keeps being sabotaged: The factory's enormous drill is destroying the Grungee's habitat in the base of the asteroid. The Grungees have been making the plant malfunction to keep their homes from being destroyed.Jane and Astro soon make their way into the factory, along with Rudy-2. Rudy stays in the factory, as Jane and Astro go below. Soon afterwards, they all find George, who had been bound and gagged by the Grungees. George has no idea why this has happened to him, untill Jane and the others explain.Shortly after this revelation, Mr Spacely arrives, and against Rudy-2's protestations, reactivates the drill, almost killing Elroy when it's actions cause a large amount of rock to collapse. The other Grungees manage to help him, and they all head top-side. After Mr Spacely refuses to stop the drill, George manage to make the system malfunction. When Spacely demands an explanation, George explains about the Grungees, and Spacely is soon found to have ignored reports that the asteroid was inhabited.A deal is made by which the Grungees operate the plant, 
 Question: what is teddy-2's father working?

Output: factory


Input: Consider Input: Context: Alpha-synuclein phosphorylated at serine 129 (S129) is highly elevated in Parkinson's disease patients where it mainly accumulates in the Lewy bodies. Several groups have studied the role of phosphorylation at the S129 in -synuclein in a rat model for Parkinson's disease using recombinant adeno-associated viral (rAAV) vectors. The results obtained are inconsistent and accordingly the role of S129 phosphorylation in -synuclein toxicity remains unclear. This prompted us to re-examine the neuropathological and behavioral effects of the S129 modified -synuclein species in vivo. For this purpose, we used two mutated forms of human -synuclein in which the S129 was replaced either with an alanine (S129A), to block phosphorylation, or with an aspartate (S129D), to mimic phosphorylation, and compared them with the wild type -synuclein. This approach was similar in design to previous studies, however our investigation of dopaminergic degeneration also included performing a detailed study of the -synuclein induced pathology in the striatum and the analysis of motor deficits. Our results showed that overexpressing S129D or wild type -synuclein resulted in an accelerated dopaminergic fiber loss as compared with S129A -synuclein. Furthermore, the motor deficit seen in the group treated with the mutant S129D -synuclein appeared earlier than the other two forms of -synuclein. Conversely, S129A -synuclein showed significantly larger pathological -synuclein-positive inclusions, and slower dopaminergic fiber loss, when compared to the other two forms of -synuclein, suggesting a neuroprotective effect of the mutation. When examined at long-term, all three -synuclein forms resulted in pathological accumulations of -synuclein in striatal fibers and dopaminergic cell death in the substantia nigra. Our data show that changes in the S129 residue of -synuclein influence the rate of pathology and neurodegeneration, with an overall deleterious effect of exchanging S129 to a residue mimicking its phosphorylated state. 
 Question: Which residue of alpha-synuclein was found to be phosphorylated in Lewy bodies?


Output: serine 129
