What is the most important reason to cite evidence in an argumentative essay?

to allow readers to learn more about the variety of research available to the public

to provide writers the opportunity to officially present the data they have gathered

to give credit for the ideas used to the appropriate sources in an organized format

to condense the information in the essay into a more reader-friendly arrangement

to give credit for the ideas used to the appropriate sources in an organized format

Explanation:

The purpose of citing sources is to give credit where credit is due. The information and data found used in an argumentative essay to give the author's ideas and credibility must be cited. Otherwise, it's considered plagiarism. While citing the sources also allows the reader to find and read the source information themselves, this is not the most important reason for citing sources.
