Task: Question Generation
Input (English): Passage: The Browns scored on their first three drives and led 20-2 early in the first quarter. The 18 point lead at the end of the first quarter was the Browns' largest lead after the 1st quarter since 1960. However, the Browns' offense stalled the rest of the game. The Ravens would score the final 23 points of the game to win 25-20. The Browns had a chance to score a go ahead touchdown on a drive with less than a minute to play, but things went wrong after a controversial taunting penalty was called on Pryor following his catch at the Ravens' 10-yard line with under 30 seconds to play. McCown would throw an interception on the next play to seal the loss. With the loss, the Browns fell to 0-2.
Output (English): how many points did the browns lead by in the first?
