Review; mixed tasks recycle vocabulary such as leadership skills, current issues, and greenhouse gas, along with listening and reading from the preceding units. The page functions as a checkpoint for the earlier language work, so it combines short language items with skills tasks rather than introducing new content. The OCR indicates a broad review section with multiple strands of practice.
