I want to know the answer to the following question:
The Cathedral Basilica of St. Louis holds the largest what?
All the background I'm provided with is that "A modern example of mosaic is the Museum of Natural History station of the New York City Subway (there are many such works of art scattered throughout the New York City subway system, though many IND stations are usually designed with bland mosaics.)". Is that enough to answer the question?
Answer: no
