Around 800 B.C.E, hunter gatherer groups started planting crops and settling near the Mississippi River (O'Brien and Kiffel-Alcheh, 2021). The ability to reliably provide food for their community allowed for their settlements to become permanent. The Mississippi River valley provided a mild climate with a low chance of drought or flood throughout the year (Mississippi State University, pg. 1). Staple crops such as maize, beans, and squash that grew in this fertile region allowed for tribes such as the Cherokee, Chickasaw, Choctaw, and Creek to flourish (History editors, 2020).

Write a paragraph that explains three places where citations are provided.

The citations in this passage provide evidence for the claims made about the history and geography of the Mississippi River valley. One citation is provided when the authors state that hunter gatherer groups began to settle near the Mississippi River around 800 B.C.E; this citation likely supports this claim with specific archaeological or historical evidence. Another citation appears when the authors discuss the mild climate of the Mississippi River valley; this citation may provide data or analysis from climate studies, or it could reference historical accounts of the region's weather patterns. Finally, a third citation is used when the authors mention the tribes that lived in the Mississippi River valley; this citation likely either provides a historical or archaeological source that identifies these tribes or draws upon existing research on the native cultures of the region. Overall, these citations help to bolster the accuracy and validity of the information presented in the passage.

In the given paragraph, three places where citations are provided are as follows:

1. "(O'Brien and Kiffel-Alcheh, 2021)": This citation indicates that the information about hunter-gatherer groups planting crops and settling near the Mississippi River around 800 B.C.E. comes from a source by O'Brien and Kiffel-Alcheh. The specific reference or publication details of this source are not provided in the paragraph.

2. "(Mississippi State University, pg. 1)": This citation indicates that the information about the mild climate and low risk of drought or flood in the Mississippi River valley comes from a source by Mississippi State University. The specific page number is mentioned as "pg. 1", which suggests that this information can be found on the first page of the source, but the complete reference or source details are not mentioned.

3. "(History editors, 2020)": This citation indicates that the information about tribes like the Cherokee, Chickasaw, Choctaw, and Creek flourishing in the Mississippi River valley due to the abundance of staple crops comes from a source by History editors. The specific publication year of this source is mentioned as "2020", but the complete reference or source details are not provided.
