I want to know the answer to the following question:
Why did the cubs need to host their home games at an alternative site?
All the background I'm provided with is that "The confusion may stem from the fact that Major League Baseball did decide that, should the Cubs make it to the World Series, the American League winner would have home field advantage unless the Cubs hosted home games at an alternate site since the Cubs home field of Wrigley Field did not yet have lights.". Is that enough to answer the question?
Answer: yes
