Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
One example: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
Solution is here: In what year did francis, duke of anjou leave the netherlands?
Explanation: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this: Coming off their divisional home win over the Panthers, the Falcons flew to Qualcomm Stadium for a Week 13 interconference duel with the San Diego Chargers. In the first quarter, Atlanta took off as kicker Jason Elam got a 35-yard field goal. The Chargers responded with RB LaDainian Tomlinson getting a 3-yard TD run, yet the Falcons stayed close with Elam getting a 40-yard field goal. In the second quarter, Atlanta regained the lead as rookie quarterback Matt Ryan completed an 18-yard TD pass to TE Justin Peelle, along with their defense forcing opposing quarterback Philip Rivers to commit intentional grounding from his own endzone, giving Atlanta a safety. In the third quarter, San Diego answered with safety Eric Weddle returning a fumble 86 yards for a touchdown (with a failed two-point conversion). In the fourth quarter, the Falcons replied with Ryan completing a 5-yard TD pass to rookie WR Harry Douglas. The Chargers tried to come back, as kicker Nate Kaeding nailed a 28-yard field goal. Atlanta's defense stiffened for the victory.
