Task: Question Generation
Input (English): Passage: One week later, Dallas faced the 1993 San Francisco 49ers season in the NFC Championship Game for the second year in a row in what was, at the time, the last NFL game to air on CBS.  The 49ers had the NFLs highest scoring offense with 473 points, 97 more than the runner-up Cowboys.  The last time the two teams played for the NFC title, Dallas won when Aikman thwarted an attempted 49ers comeback with a touchdown drive late in the fourth quarter.  But this time, the game was extremely one-sided.  The Cowboys scored touchdowns on four of their five first-half possessions.  By the end of the half, Dallas had a commanding 28-7 lead.  Aikman completed 14 of 18 passes for 177 yards and three touchdowns with no interceptions, while also rushing for 25 yards, but was knocked out of the game with a concussion in the third quarter.  Then San Francisco scored a touchdown, making the score 28-14 with plenty of time left for a comeback.  However, their hopes were soon dashed as backup quarterback Bernie Kosar, who had already played in three conference championship games and was unable to advance to the Super Bowl each time, led the Cowboys 82 yards to go up 35-14 on his 42-yard touchdown pass to Alvin Harper.  Murray then put the finishing touches on San Francisco with a 50-yard field goal, while all the 49ers could do was score a useless touchdown in "garbage time" to make the final score 38-21.  Smith rushed for 88 yards, caught seven passes for 85 yards, and scored two touchdowns.  Meanwhile, the Dallas defense held 49ers running back Ricky Watters, who rushed for over 100 yards and scored 5 touchdowns in the divisional round, to just 37 yards on 12 carries.
Output (English): How many points were the Cowboys winning by at the end of the half?
