Briefing

You grouped loot in the Lockward. Now average salinity per pool — AVG is the new piece.

Objective

Return pool_name and AVG(salinity) as avg_salinity, grouped by pool, ordered by pool_name.

Hint

GROUP BY pool_name with AVG — then ORDER BY pool_name.

Warden

I am the Warden. Ask for a hint, paste a failing query, or request a review — I won't hand you the full answer.
