I want to know the answer to the following question:
Which other large religion also exist in Alsace due to the once German presence?
All the background I'm provided with is that "Most of the Alsatian population is Roman Catholic, but, largely because of the region's German heritage, a significant Protestant community also exists: today, the EPCAAL (a Lutheran church) is France's second largest Protestant church, also forming an administrative union (UEPAL) with the much smaller Calvinist EPRAL.". Is that enough to answer the question?
Answer: yes
