Example of paragraph unity?
Unity in a paragraph is making sure that everything "flows." The
paragraph should always begin with a topic sentence, such as "One
of the reasons the climate is changing is because of pollution."
From then on, whatever is being said must support the topic
sentence. If you make claims, they need to be supported by logic.
An example of a paragraph that would not be unified would be by
inserting a random fact about your dog in a paragraph about global
warming. They're not related, nor does your dog have an relevance
to global warming.
