Tier II words are defined as words that

• A. High-frequency words used in everyday speech.
• B. Low-frequency domain-specific terms learned within a lesson.
• C. Words that are spelled the same in many languages.
• D. Words that occur across contexts, enhancing comprehension.

Answer: (D)

Tier II words are high-utility vocabulary that tends to appear across many subjects and in a range of contexts, which helps readers understand a wide array of texts. These words aren’t the everyday basic terms, nor are they limited to one topic; they carry precise meaning and show up in science, literature, social studies, and other domains, so students can apply them in different situations and boost comprehension when encountering unfamiliar material. The other options describe basic everyday words (Tier I), domain-specific terms tied to a single lesson (Tier III), or a feature about spelling across languages, which isn’t about how often they appear or how they support understanding.
