Answer:
He uses a mix of long and short sentences.
Step-by-step explanation:
In the given passage, Frederick Douglass uses a mix of long and short sentences to vary his sentence structure and make his writing more interesting for the reader. For instance, the first sentence is a short and declarative sentence that expresses his intention to take to the water to gain freedom. The second sentence is longer and more complex, explaining his plan in detail. Then he uses another short sentence to conclude his thought. By mixing the length of the sentences, Douglass creates a rhythm and flow to his writing, which keeps the reader engaged and interested in the story.
