A paragraph should always end with a strong?

Not necessarily. A paragraph does not always have to end with a strong sentence. While a strong ending can leave a lasting impression on the reader, the most appropriate way to conclude a paragraph depends on the context and the writer's intention. Different types of paragraphs may have different purposes and conclusions. For example, in an argumentative or persuasive paragraph, a strong and impactful conclusion may be more effective to reinforce the main point, whereas in a descriptive paragraph, a subtle or reflective ending might be more suitable to create a specific atmosphere or mood. Ultimately, the goal is to ensure the paragraph flows coherently and achieves the desired impact on the reader.
