Problem: The Macintosh (/ˈmækᵻntɒʃ/ MAK-in-tosh; branded as Mac since 1997) is a series of personal computers (PCs) designed, developed, and marketed by Apple Inc. Steve Jobs introduced the original Macintosh computer on January 24, 1984. This was the first mass-market personal computer featuring an integral graphical user interface and mouse.

Since 1998, Apple has largely phased out the Macintosh name in favor of "Mac", though the product family has been nicknamed "Mac" or "the Mac" since the development of the first model.

Problem: On September 23, 1908, the Cubs and New York Giants were involved in a tight pennant race. The two clubs were tied in the bottom of the ninth inning at the Polo Grounds, and N.Y. had runners on first and third and two outs when Al Bridwell singled, scoring Moose McCormick from third with the Giants' apparent winning run, but the runner on first base, rookie Fred Merkle, left the field without touching second base. As fans swarmed the field, Cub infielder Johnny Evers retrieved the ball and touched second. Since there were two outs, a forceout was called at second base, ending the inning and the game. Because of the tie the Giants and Cubs ended up tied for first place. The Giants lost the ensuing one-game playoff and the Cubs went on to the World Series.
Who was the runner on first base?
The answer is the following: Fred Merkle

This capped the first year of declining PC sales to the Asia Pacific region, as consumers bought more mobile devices than Windows PCs.
