I want to know the answer to the following question:
What is the largest city in the ACAL region of France?
All the background I'm provided with is that "German: Straßburg, [ˈʃtʁaːsbʊɐ̯k]) is the capital and largest city of the Alsace-Champagne-Ardenne-Lorraine (ACAL) region in eastern France and is the official seat of the European Parliament.". Is that enough to answer the question?
