College Composition CLEP 2026 Complete Practice Exam

An author should use formal language when writing because it is considered more appropriate and typically used in professional or academic settings. Using technical language (choice B) may be useful when discussing a specific subject and with a specialized audience, but it may be difficult for the average reader to understand. Casual language (choice C) is too informal and may not convey the seriousness or importance of the topic being discussed. Folksy language (choice D) is not appropriate for most writing situations as it is too casual and may come across as condescending or unprofessional. Therefore, formal language is the most suitable and effective choice for writing.
