How this list was built
These 120 words are the Environment vocabulary in Reach120's bank, chosen from the 171 words tagged with this subject. 120 of them were mined from Reach120's own 2026-format passages, talks and question stems, and the least common of those still appears in 3 separate documents. Reach120 wrote this practice material for the 2026 format — it is not ETS content, and any band figure beside it is a Reach120-scored estimate, not an ETS score.
