to the passage below and then answer the question afterwards in the same language as the passage: Passage: To be assigned an Erdős number, someone must be a co-author of a research paper with another person who has a finite Erdős number. Paul Erdős has an Erdős number of zero. anybody else's Erdős number is k + 1 where k is the lowest Erdős number of any co-author. The American Mathematical Society provides a free online tool to determine the Erdős number of every mathematical author listed in the Mathematical Reviews catalogue.Erdős wrote around 1,500 mathematical articles in his lifetime, mostly co-written. He had 511 direct collaborators; these are the people with Erdős number 1.
