Which level is known for using organized expression of ideas and a variety of sentence patterns?

The correct choice indicates that Level 4 is characterized by the organized expression of ideas and the use of a variety of sentence patterns. At this level, language learners demonstrate an ability to construct complex thoughts and articulate them clearly, which is essential for academic success. This involves using a range of grammatical structures and vocabulary to express nuanced ideas effectively.

In contrast, lower levels tend to focus on more basic sentence structures and may lack clarity in expressing complex concepts. Levels 2 and 3 are often centered around simpler forms of communication and may not exhibit the same level of fluency or sophistication in writing and speaking. Level 5, while advanced, is primarily associated with proficiency that includes a high degree of fluency and spontaneity rather than just focused on organizing ideas and varied sentence patterns. Therefore, Level 4 is rightly positioned as the stage where organized and varied expression becomes a primary focus.
