Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Let me give you an example: Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.
Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
The answer to this example can be: Saint Bernadette Soubirous
Here is why: This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.

Context: Coming off a primetime victory over Cincinnati, the Colts flew to Reliant Stadium for an AFC South rematch with the Houston Texans. Heading into this game, Indianapolis had never lost a game to the Texans, winning their first 9 games against them. In the first quarter, the Colts got an early shock as RB Ron Dayne ran for a 3-yard touchdown and a 6-yard touchdown run. Indianapolis would respond with 37-yard touchdown pass from QB Peyton Manning to WR Marvin Harrison. In the second quarter, the Colts tied the game with Manning completing a 9-yard touchdown pass to WR Aaron Moorehead. However, Houston reclaimed its lead with QB David Carr's 3-yard touchdown pass to RB Vonta Leach. In the third quarter, Indianapolis crept closer with K Adam Vinatieri making a 33-yard field goal for the only score of the period. In the fourth quarter, the Texans responded with kicker Kris Brown's 42-yard field goal. Afterwards, the Colts tied the game with Manning hooking up with Harrison again on a 7-yard touchdown pass, Harrison's second of the game. However, Houston managed to pull off a huge upset with Kris Brown's game-winning 48-yard field goal as time expired, giving Indianapolis their first ever loss against them. With the loss, the Colts fell to 11-4. Colts QB Peyton Manning finished the game 21 of 27 for 205 yards passing with three touchdowns and Texans QB David Carr finished with 163 passing yards on completing 16 of 23 passes with one touchdown.
