If the file contains multiple lines of text, the newline characters will be embedded in this string. The next session shows how to use the method read:

After input is finished, another call to read would return an empty string, to indicate that the end of the file has been reached. To repeat an input, the file must be re-opened. It is not necessary to close the file.

The writer did not follow my choice of topic (Food/Water Insecurity, Hunger, & Poverty), the paper was instead written about Climate Change in Africa. However, the paper was still great and informative. Thank you!
