I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The official Cubs team mascot is a young bear cub, named Clark, described by the team's press release as a young and friendly Cub. Clark made his debut at Advocate Health Care on January 13, 2014, the same day as the press release announcing his installation as the club's first ever official physical mascot. The bear cub itself was used in the clubs since the early 1900s and was the inspiration of the Chicago Staleys changing their team's name to the Chicago Bears, due to the Cubs allowing the football team to play at Wrigley Field in the 1930s."?
A:
What is Clark?
