a central idea or dominant impression that comes across throughout the writing

a clear organizational structure
facts and examples to support the writer's ideas
vivid descriptive details that appeal to the senses and create a "verbal picture"

a strong and cohesive writing style that engages the reader

logical and coherent reasoning that connects ideas and supports the main argument
effective use of language, including appropriate vocabulary and grammar
a persuasive tone that convinces the reader of the writer's point of view
proper citation and use of sources to provide evidence and credibility to the writer's claims

These are four key elements of effective writing:

1. Central Idea or Dominant Impression: This refers to the main message or theme that the writer intends to convey to the reader. It is the core concept that ties the entire piece of writing together. A strong central idea provides coherence and focus to the writing.

2. Clear Organizational Structure: A well-structured piece of writing follows a logical arrangement that enables readers to understand the flow of ideas easily. This typically includes an introduction, body paragraphs with supporting details, and a conclusion. A clear organizational structure enhances readability and helps readers follow the writer's argument or narrative.

3. Facts and Examples: Effective writing incorporates factual information and relevant examples to support the writer's ideas. By presenting evidence or specific instances, the writer can strengthen their arguments and make the writing persuasive. Facts and examples provide credibility and create a connection between the reader and the topic being discussed.

4. Vivid Descriptive Details: Using descriptive details helps to create a vivid mental image in the reader's mind. This engages the reader's senses and makes the writing more engaging and memorable. Descriptive language appeals to sight, sound, taste, touch, and smell, adding depth and richness to the writing. By painting a "verbal picture," the writer can evoke emotions and create a more immersive experience for the reader.

The concepts you mentioned are important elements of effective writing. Let me break down each one and explain how they contribute to creating a strong piece of writing.

1. Central Idea/Dominant Impression: This is the main point or theme that the writer wants to convey to the reader. To identify the central idea, start by reading the text and looking for recurring themes, motifs, or messages. The central idea should be evident through careful analysis of the main arguments or main points the author presents.

2. Clear Organizational Structure: A well-organized piece of writing follows a logical and coherent structure. This means that the ideas flow logically from one point to another. Look for clear topic sentences that introduce each paragraph's main idea and ensure that there is a smooth transition between paragraphs. You may also find the use of subheadings or bullet points helpful in organizing the content.

3. Facts and Examples: Supporting the central idea with relevant facts and examples strengthens the writer's argument and adds credibility. Effective writers use evidence to back up their claims and establish their authority on the subject. When analyzing a text, look for well-researched facts, statistics, expert opinions, or specific examples that support the writer's ideas.

4. Vivid Descriptive Details: Descriptive language appeals to the reader's senses and creates a more engaging reading experience. Look for literary devices such as similes, metaphors, vivid adjectives, and sensory details (sight, sound, taste, touch, smell) that bring the writing to life. These details help the reader visualize the ideas and enhance their understanding and connection to the text.

To determine if a piece of writing possesses these qualities, read the text carefully and critically. Pay attention to the content, structure, and language used. Take notes on the main ideas, supporting evidence, and descriptive details. Analyze how these elements work together to create a unified and impactful piece of writing.
