I want to know the answer to the following question:
What is the predominant language in the region of Alace?
All the background I'm provided with is that "With a population of 768,868 in 2012, Strasbourg's metropolitan area (only the part of the metropolitan area on French territory) is the ninth largest in France and home to 13% of the ACAL region's inhabitants.". Is that enough to answer the question?
