Final answer:
A narrative essay is a type of essay that tells a story. A well-written paragraph should focus on a single idea and have a topic sentence. Transitions are essential for linking and separating ideas in writing.
Step-by-step explanation:
The purpose of a narrative essay is to tell a story. It is a type of essay where the writer narrates an event or an experience to engage the reader. Unlike expository essays that focus on delivering information, narrative essays aim to entertain or evoke emotions in the reader.
A well-written paragraph should focus on a single, coherent idea and have a topic sentence that introduces that idea. It should also have supporting details and a concluding sentence to effectively convey the main point.
Transitions in writing link ideas and separate ideas to ensure a smooth flow of information. They can also inform/explain or interest the reader. Therefore, transitions serve various purposes in writing.
In the given example, the supporting sentence for the topic sentence 'Young children should not be allowed to cross a highway by themselves' would be 'Last year, two children were injured while crossing it.' This sentence provides evidence to support the topic sentence's argument.
The correct transition in the given example is 'no matter.' It is used to indicate that regardless of people's preference for smokeless cigarettes, they did not like the taste of the product in question.
