Due to his many interests and pursuits, Eratosthenes dabbled in a variety of fields, and he is credited with a theory known as the sieve of Eratosthenes. This is an early algorithm used to determine prime numbers. To which section of the library should Jorgen go to find out more about the current applications of the sieve of Eratosthenes?
Correct Answer: D
Rationale: Jorgen should go to the 500 section of the library, which is dedicated to science and mathematics. The sieve of Eratosthenes is a mathematical concept, so current applications and research related to it would be found in this section. Choice A (0) is incorrect as it is for general works. Choice B (100) is for philosophy and psychology, which are unrelated to mathematics. Choice C (400) is for languages, not mathematics.
