What is the best way to improve the sentence fluency in the paragraph? a. vary the beginnings of the sentences. b. create more vivid images. c. combine sentences 4 and 5. d. rewrite to keep a consistent tone.

I believe the answer is D. Rewrite to keep a consistent tone. When we write, we write in sentences. Beginning with a capital letter, we wind our way over words and phrases until we've expressed a complete thought, and then we mark the an endpoint with a period, question mark, or exclamation mark. Readers read the same way: they follow the shape of each sentence from beginning to end trying to understand the single complete thought the writer is expressing. In order for readers to do that, your writing needs to flow smoothly from word to word, phrase to phrase, and sentence to sentence.
