Question: What Pixar short written by the originator and co-director of Pixar's Oscar-winning 2007 film "Ratatouille" won an Academy Award for Best Animated Short Film in 1998?
Sentence (from "Geri's Game"): Although Pixar had started out with a successful string of shorts in the 1980s, these were put on hold for most of the 1990s to focus on for-hire work, and development of the feature films "Toy Story" and "A Bug's Life"; "Geri's Game" was the first Pixar short since the 1989 short "Knick Knack".
Relevant evidence: No
