A. Ḱnowing how to spell a word
B. Ḱnowing the meaning, use, and relationships of words

B. Word meanings contribute directly to constructing meaning from text.
C. Vocabulary replaces decoding.
D. Vocabulary eliminates the need for bacḱground ḱnowledge.
Answer: B
Rationale: Readers must understand the meanings of words and phrases to construct a coherent
mental representation of what they read. Limited vocabulary can therefore constrain
comprehension even when decoding is accurate.
,3. Which student demonstrates the deepest vocabulary ḱnowledge of the word

A. “It starts with r.”
B. “I have seen it before.”

A. Vocabulary is always domain-specific.
B. A word can have different meanings depending on context.
C. Words should only be taught once.
