I want to know the answer to the following question:
When did Chaucer die?
All the background I'm provided with is that "The publication of vernacular literature increased, with Dante (d. 1321), Petrarch (d. 1374) and Giovanni Boccaccio (d. 1375) in 14th-century Italy, Geoffrey Chaucer (d. 1400) and William Langland (d. c. 1386) in England, and François Villon (d. 1464) and Christine de Pizan (d. c. 1430) in France.". Is that enough to answer the question?
Answer: yes
