Suppose Mozart's Symphony No. 40 is one of his most well-known works, composed in 1788. The piece is in sonata form and is scored for flute, two oboes, two bassoons, two horns, and strings. The symphony is in the key of G minor and is often praised for its dramatic and emotional depth.
Can we infer that "Mozart composed Symphony No. 40 in his old age."? Yes, no, or maybe?
