Input: Consider Input: Question: Who did Vinny Del Negro play for before he signed with the Spurs? Passage:The 1992–93 NBA season was the Spurs' 17th season in the National Basketball Association, and 26th season as a franchise. During the offseason, Terry Cummings suffered a serious knee injury and only played in the final eight games of the season. With the acquisition of Dale Ellis from the Milwaukee Bucks and signing free agent Vinny Del Negro, plus re-signing Avery Johnson after a brief stint with the Houston Rockets, the Spurs struggled with a 9–11 start to the season as new head coach Jerry Tarkanian was fired. After playing one game under Rex Hughes, the team hired John Lucas II as their new coach. At midseason, they acquired J.R. Reid from the Charlotte Hornets. Under Lucas, the Spurs would play solid basketball posting a 10-game winning streak in January, then winning eight straight in February, finishing second in the Midwest Division with a 49–33 record. David Robinson and Sean Elliott were both selected for the 1993 NBA All-Star Game.

Input: Consider Input: Question: Has the voice actor for the White Rabbit voiced any other characters? Passage:The film follows the storyline of the book closely, save for adding some scenes from Through the Looking-Glass. It also changes the opening real world scene from Alice and her sister sitting at a riverbank to Alice in her bedroom, reluctantly practicing the song "Cherry Ripe", which she is expected to perform at a garden party. (The party guests are played by the same actors as the Wonderland characters and are shown as resembling them in appearance and personality, in a similar manner to the MGM version of The Wizard of Oz. The toys in Alice's room also reflect the residents of Wonderland). Thanks to stage fright and constant nagging from her confident governess (Dilys Laye), Alice runs out of the house and hides herself in the woods nearby, planning to stay hidden until the party has ended. However, an apple floats down from the tree and seems to hover in Alice's face. She is suddenly distracted by a human-sized White Rabbit (voiced by Richard Coombs) rushing by. Curious, Alice follows the White Rabbit, falling down his rabbit hole and ending up in Wonderland.
 Links: a. Dilys Laye b. Bedroom c. Richard Coombs d. White Rabbit

Output: c


Input: Consider Input: Question: How old was Jimmy Duncan's father when Goldwater ran for president? Passage:Duncan was born in Lebanon, Tennessee. His "paternal grandparents were small-areage farmers in Scott County, which in 1861 left Tennessee, refusing to follow the Volunteer State into the Confederacy, and declared itself 'the Free and Independent state of Scott.'" Duncan's parents were Lois (Swisher) and John Duncan Sr., who "hitchhiked into Knoxville with five dollars in his pocket,' and after an education at the University of Tennessee was elected mayor of Knoxville and then congressman." The elder Duncan was also a co-owner of the Knoxville Smokies of the "Sally League," for which his son "was a batboy, a ball shagger, scoreboard operator, and, as a freshman at the University of Tennessee, the Smokies' public-address announcer." Duncan also worked as a grocery bagger and salesman at Sears while working his way through school. Duncan supported Barry Goldwater's 1964 presidential campaign, and sent the first paycheck he earned as a bagboy at the local A&P to the Goldwater campaign.
