Hi. You did not provide any response options. This makes it difficult for your question to be answered. However, we can consider that keeping the focus is a quality of a good writing that allows the main idea of the text to be kept until the end of it.
Explanation:
An essay that keeps the focus throughout the text is an essay that manages to keep its main idea and work on it in every paragraph, being specific and not losing the main subject. This keeps the text cohesive and well-established, keeping the reader well informed about the topic discussed and preventing the text from getting confused.
