What is included in the glossary of Book 3-2?

The glossary in Book 3-2 serves as a valuable resource by providing key terms and definitions specifically related to language concepts. This inclusion aids students and educators in understanding essential vocabulary that is foundational to the material presented in the book. Clear definitions help clarify concepts, allowing learners to grasp the subject matter more fully and enhance their comprehension of the language content discussed throughout the text.

The other options, while potentially beneficial resources in an educational context, do not align with the primary function of a glossary. Instead, they focus on different aspects, such as providing additional educational materials or offering context, which are not the typical purpose of a glossary in a language-focused book.
