Task: Question Generation
Input (English): Passage: The Seahawks met the 3-0 Chicago Bears in a primetime matchup of NFC powerhouses at Soldier Field. The Seahawks took the lead on an early field goal, but momentum quickly shifted to the hometown Bears. Two Matt Hasselbeck interceptions midway through the 2nd quarter led to 10 Chicago points and a 20-6 halftime lead. Any hopes for a comeback were erased after the Bears scored a touchdown on their first possession of the second half for a 27-6 lead. The Seahawks running attack was diminished without the injured Shaun Alexander. Near constant pressure on Hasselbeck, including 5 sacks, thwarted the effectiveness of the 4 receiver offense that had confused the Giants the week before. The team flight back to Seattle was diverted to South Dakota for a "medical emergency", which turned out to be Defensive Consultant Ray Rhodes feeling ill after the game. He was checked out at a Rapid City, South Dakota hospital and released. With the loss, the Seahawks went into their bye week at 3-1.
Output (English): How many points did the Bears lead by at halftime?
