Task: Question Answering
Input (English): Passage: Coming off their win over the Eagles, the Patriots returned home for an AFC duel with the Indianapolis Colts. The Patriots took the early lead, with a 39-yard field goal by Stephen Gostkowski, before placekicker and former Patriots Super Bowl hero Adam Vinateri hit back with a 31-yard field goal of his own early in the second quarter. The Patriots then reeled off 28 unanswered points, starting with quarterback Tom Brady tossing an 11-yard touchdown pass to tight end Rob Gronkowski, a 1-yard touchdown run by running back BenJarvus Green-Ellis just before halftime, then Brady threw two more touchdown passes to Gronkowski in the third quarter - a 21-yarder followed by a 2-yarder. In the fourth quarter, the Patriots were held scoreless and the Colts reeled off 21 unanswered points - a 5-yard touchdown run by running back Donald Brown, followed by two touchdown passes from Dan Orlovsky to wide receiver Pierre Gar&#231;on - a 33-yarder and a 12-yarder - the latter with 36 seconds remaining in regulation. Despite the touchdowns, one of Gar&#231;on's catches in the end zone was accompanied with an angry throw at a sign with a target meant for Gronkowski's trademark spike. A Colts' onside kick attempt near the end of the contest was unsuccessful, sealing the win for the Patriots. 
Question: How many touchdown receptions did Rob Gronkowski catch?
