Task: Question Answering
Input (English): Passage: The Giants were in control of the winless Chiefs from the opening kickoff, which Bryan Kehl recovered after a Jamaal Charles fumble. The Giants proceeded to score on their first possession for the fourth straight week, this time on a short pass to Smith. Smith himself went on to have a busy day, with 11 catches for 134 yards and a 25-yard touchdown in the second quarter as well. Nicks returned from his Week 1 injury and scored his first career touchdown, a 54-yard pass from Manning, in the fourth quarter. Late in the game, the Chiefs put up a brief flurry of offense; quarterback Matt Cassel threw touchdowns to tight end Sean Ryan and wide receiver Bobby Wade within a span of about five minutes. But the comeback fell short, and the Giants improved to 4-0. Manning suffered a heel injury in the fourth quarter, and was forced to leave the game early. Initially concerned about a possible Achilles tendon injury, he was later diagnosed with plantar fasciitis; his start against the Raiders was to be a game-time decision. 
Question: How many TDs did the Chiefs have in the fourth quarter? 
Answer type: Number 
Output (English): 2.
