QUESTION 20 In a bibliography, how many names of authors are listed? A. Only ten authors B. The first one only C. The first and the second D. Names of all the writers involved

A bibliography is a list of all the sources (books, articles, websites, etc.) that you have used or referred to in your research for a piece of writing. Its primary purpose is to give credit to the original authors and to allow your readers to find the sources themselves.

In academic writing, when you list a source in a bibliography (or a "Works Cited" or "References" list, depending on the citation style), the goal is to provide complete information about that source. This includes listing all the individuals who contributed to the work as authors. While some citation styles might use "et al." (and others) for in-text citations or for sources with a very large number of authors (e.g., more than 20 in APA 7th edition), the general principle for a bibliography entry is to list all authors to fully credit their work.

• A. "Only ten authors": This is not a universal rule for all bibliographies or citation styles.
• B. "The first one only": This is typically used for in-text citations when there are many authors, not for the full bibliography entry.
• C. "The first and the second": Similar to option B, this is an abbreviation strategy, not a comprehensive listing for a bibliography.
• D. "Names of all the writers involved": This option best reflects the purpose of a bibliography, which is to provide full credit and complete information for each source, including all contributing authors.

The final answer is $\boxed{\text{D. Names of all the writers involved}}$
