Answer:
Newspaper article
Explanation:
Newspaper articles are the most timely and up-to-date. As the newspapers are intended to be read within a day, and they are published daily, they have to provide the most recent information.
Encyclopedia is a book or set of books containing information on many subjects, or many aspects of a single subject.
Field guides help the readers about the field (usually a natural field), natural park, mountain range, riverside, and beach etc.
Autobiography is writer's own life story usually written by himself.
Field-guide, autobiography, and encyclopedia are not published and updated daily; hence they don't have up-to-date information.
