Task 6 is poorly worded. And my correct solution does not pass the test! It must because the error in previous question are not checked properly. See my solution below: SELECT DISTINCT country_name, FROM `qwiklabs-gcp-02-beec5aadcaeb.covid_294.oxford_policy_tracker_807` WHERE population IS NULL UNION ALL SELECT DISTINCT country_name FROM `qwiklabs-gcp-02-beec5aadcaeb.covid_294.oxford_policy_tracker_807` WHERE country_area IS NULL ORDER BY country_name ASC
