Option 1 -> The passage criticizes test-focused teaching, stating that meaningful qualities "cannot be tested."
Option 2 -> The text explicitly states "They were empowered to unlock our potential" - teachers had freedom to approach each student individually.
Option 3 -> This contradicts the passage; the writer's curiosity was nurtured, not curbed, by these teachers.
Option 4 -> Teachers were specifically described as "free" from test prep constraints, not working within strict confines.
Hence, Option 2 -> The writer clearly explains that teachers were empowered because they had the freedom to treat each student as "an individual puzzle" and focus on unlocking their unique potential, rather than being constrained by standardized test preparation -> correct
