Suppose Ludwig van Beethoven was a German composer and pianist. He was a crucial figure in the transition between the Classical and Romantic eras in Western art music. His best-known compositions include 9 symphonies, 5 piano concertos, 16 string quartets, 32 piano sonatas, 16 string quartets, one opera, and the great Mass the Missa solemnis.
Can we infer that "Beethoven wrote 50 symphonies."? Yes, no, or maybe?
