Input: Consider Input: Question: How many pages long was Strout's first novel? Passage:Strout's first novel, Amy and Isabelle (1998) met with widespread critical acclaim, became a national bestseller, and was adapted into a movie starring Elisabeth Shue.

The novel won the 2009 Pulitzer Prize for Fiction. The book was adapted into a multi Emmy Award-winning mini series and became a New York Times bestseller.

Input: Consider Input: Question: How many dollars in damage did the storm do which forced the game's start time to be changed to 12:35 PM? Passage:For 2003, he signed with the Baltimore Orioles and again spent a few games in the majors. His most notable performance as a major leaguer occurred at Camden Yards on September 18, 2003. An attempt to avoid Hurricane Isabel by changing the game's start time from 7:05 pm (ET) to 12:35 pm proved futile as the contest was played entirely in a downpour. With the score tied at one, Swann opened the bottom of the fifth inning with a double off Mike Mussina. When Brian Roberts hit a one-out single to left field, Orioles third-base coach Tom Trebelhorn had initially waved Swann home. He abruptly put up the stop sign when left fielder Hideki Matsui quickly threw the ball to third baseman Aaron Boone. Swann, who was too far past third base, got caught in a rundown and was tagged out. When the inning ended with the Orioles failing to score a run, the match was suspended and replayed in its entirety eight days later on September 26 as part of a twi-night doubleheader at Yankee Stadium. The Orioles would have had a 2–1 victory had Swann successfully crossed home plate because the game became official upon the completion of the fifth inning.
