premise: Aziyadé (1879; also known as Constantinople) is a novel by French author Pierre Loti. Originally published anonymously, it was his first book, and along with "Le Mariage de Loti" (1880, also published anonymously), would introduce the author to the French public and quickly propel him to fame; his anonymous persona did not last long.
hypothesis: "Le Mariage de Loti" is the sequel to Aziyadé.
reason: Based on the statement alone, it is impossible to know if "Le Mariage de Loti" is a sequel to Aziyadé or if it was a standalone book. The system knew that "Le Mariage de Loti" was published after Aziyadé and may have thought there was a higher chance of it being a sequel.
