When preparing to write a letter, why is it essential to identify what information is not needed?

Identifying what information is not needed is crucial because it helps maintain clarity and relevance in your writing. When you focus on including only the necessary information, you ensure that the reader can easily understand the main points and purpose of the letter. This approach prevents confusion that may arise from excessive details, allowing the reader to grasp the key message without being distracted or overwhelmed.

In professional communication, such as in the context of the Occupational English Test, being concise and specific is especially important. It reflects the writer's ability to prioritize information that is pertinent to the reader, thereby enhancing the effectiveness of the communication.
