Answer:
by providing places for the reader to pause
Step-by-step explanation:
In this text, the reader employs a period every time he finishes a sentence or an important idea. This is appropriate according to the rules of grammar. Periods are meant to indicate separation between different ideas. When reading aloud, periods indicate pauses in the reading. The reader should pause at a period in order to make the reading more fluent. It also allows listeners to better understand the ideas of the text.
