3. Key: B — re- (again) + -able (can be); able to be sealed again.

4. Key: A — -ness converts adjective to noun meaning state of being bright.

Part 2: Passage Investigation (2 pts each = 4 pts)

5. untrustworthy (2 pts): 1 pt for identifying base (trust), prefix (un-), and suffix (-worthy); 1 pt for inferring meaning: not worthy of trust, dangerous, or unsafe to use.

6. calmness (2 pts): 1 pt for identifying base (calm) and suffix (-ness); 1 pt for inferring meaning: the condition of staying peaceful, steady, and not panicking.

Part 3: Word Repair Lab (2 pts)

Correction (1 pt): Change uselessness to useless.

Explanation (1 pt): The sentence needs an adjective to describe the map ("The map was completely useless"). Adding -ness turns it into a noun, which is grammatically incorrect in this predicate adjective position.

Performance Bands: 9–10 pts: Advanced Mastery 7–8 pts: Proficient 5–6 pts: Approaching (Targeted Intervention) <5 pts: Remediation Required
