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.

[EX Q]: Context: Telomeres may regulate human disease by at least two independent mechanisms. First, replicative senescence occurs once short telomeres generate DNA-damage signals that produce a barrier to tumor progression. Second, telomere position effects (TPE) could change gene expression at intermediate telomere lengths in cultured human cells. Here we report that telomere length may contribute to the pathogenesis of facioscapulohumeral muscular dystrophy (FSHD). FSHD is a late-onset disease genetically residing only 25-60 kilobases from the end of chromosome 4q. We used a floxable telomerase to generate isogenic clones with different telomere lengths from affected patients and their unaffected siblings. DUX4, the primary candidate for FSHD pathogenesis, is upregulated over ten-fold in FSHD myoblasts and myotubes with short telomeres, and its expression is inversely proportional to telomere length. FSHD may be the first known human disease in which TPE contributes to age-related phenotype. 
 Question: Which disease is associated with the ectopic expression of the protein encoded by the gene DUX4?
[EX A]: fshd

[EX Q]: Context: The Texans' ninth match was an AFC South rivalry match against the Jaguars at EverBank Field. In the first quarter the Texans trailed early as kicker Josh Scobee hit a 38-yard field goal. They replied after kicker Neil Rackers made a 24-yard field goal. They trailed again in the 2nd quarter with RB Maurice Jones-Drew getting a 3 and a 9-yard TD run. However, the lead didn't last long after RB Arian Foster got a 1-yard TD run, and QB Matt Schaub threw a 9-yard TD pass to WR Andre Johnson. The Jaguars stayed in the lead when QB David Garrard completed a 52-yard TD pass to TE Zach Miller, but the Texans replied again with Schaub finding WR Kevin Walter on an 18-yard TD pass. Suddenly, the Texans' defense broke through with only a few seconds remaining after Garrard made a 50-yard TD pass to WR Mike Thomas. The ball was batted into his hands by Texans Defensive back Glover Quin, who made an attempt to bat the ball to the ground. 
 Question: In what quarter did both teams score a field goal?
[EX A]: first quarter
