# bird-bench / toxicology__196 - taskset: [bird-bench](https://harnessreport.com/tasks/bird-bench.md) - difficulty: hard - category: database - language: - runnable from the site: no - agent timeout: 3600s ## Results by harness _none yet_ ## Instruction ``` You are given a natural language question and a SQLite database. Your task is to write a SQL query that answers the question. Database file: `/app/db.sqlite` You may use `sqlite3` or Python to inspect the schema and data. Do not modify the database. Question: For non-carcinogenic molecules containing chlorine, what are the statistics including the count of such molecules, average and maximum number of chlorine atoms, average number of bonds, count of molecules with more single bonds than double bonds, and average number of bonds involving chlorine? Evidence: non-carcinogenic molecules refers to label = '-'; chlorine atoms refers to element = 'cl'; single bonds refers to bond_type = '-'; double bonds refers to bond_type = '=' Schema: CREATE TABLE `atom` ( `atom_id` TEXT NOT NULL, `molecule_id` TEXT DEFAULT NULL, `element` TEXT DEFAULT NULL, PRIMARY KEY (`atom_id`), FOREIGN KEY (`molecule_id`) REFERENCES `molecule` (`molecule_id`) ) CREATE TABLE `bond` ( `bond_id` TEXT NOT NULL, `molecule_id` TEXT DEFAULT NULL, `bond_type` TEXT DEFAULT NULL, PRIMARY KEY (`bond_id`), FOREIGN KEY (`molecule_id`) REFERENCES `molecule` (`molecule_id`) ) CREATE TABLE `connected` ( `atom_id` TEXT NOT NULL, `atom_id2` TEXT NOT NULL, `bond_id` TEXT DEFAULT NULL, PRIMARY KEY (`atom_id`,`atom_id2`), FOREIGN KEY (`atom_id`) REFERENCES `atom` (`atom_id`) ON DELETE CASCADE ON UPDATE CASCADE, FOREIGN KEY (`atom_id2`) REFERENCES `atom` (`atom_id`) ON DELETE CASCADE ON UPDATE CASCADE, FOREIGN KEY (`bond_id`) REFERENCES `bond` (`bond_id`) ON DELETE CASCADE ON UPDATE CASCADE ) CREATE TABLE `molecule` ( `molecule_id` TEXT NOT NULL, `label` TEXT DEFAULT NULL, PRIMARY KEY (`molecule_id`) ) Output: Write ONLY the SQL query to `/app/answer.sql`. Do not include code fences, comments, or explanations. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
