Ruth Plumly Thompson (27 July 1891 – 6 April 1976) was an American writer of children's stories, best known for writing many novels placed in Oz, the fictional land of L. Frank Baum's classic children's novel "The Wonderful Wizard of Oz" and its sequels.
Ruth Plumly Thompson was born in the year that immediately comes after 1889.
It's definitely incorrect because she was born in 1891, not 1890. The system does not appear to know what "immediately comes after" means in terms of years.
