Task: Question Generation
Input (English): Passage: Another set of back-to-back losses came in controversial circumstance for the 49ers that saw the team slip to 6-4. The 49ers lead 20-17 with under 5 minutes to go in the final quarter, before two Garrett Hartley field goals won it for the Saints, the second as time expired. On the drive leading to the first or these field goals, linebacker Ahmad Brooks was flagged for a contentious personal foul on Drew Brees for a blow to the neck on a sack and fumble, leading to a 15-yard penalty. Colin Kaepernick's three and out between the field goals also was a major contributor to the Saints' victory.
Output (English): How did the 49ers lose the lead?
