Task 1 should explicitly say that the expiration date relates to the partition and not to the table. The current wording is confussing.

This lab is INCORRECT. Task 4 says "Delete data from the oxford_policy_tracker_by_countries table in the covid_data BigQuery dataset where the population and country_area value is null." DELETE FROM covid_data.oxford_policy_tracker_by_countries WHERE population is Null AND country_area is null; should be the solution. But it is incorrect. The lab requires using an OR instead of AND. Therefore the question is WRONG. DELETE FROM covid_data.oxford_policy_tracker_by_countries WHERE population is Null OR country_area is null; It should say "Delete data from the oxford_policy_tracker_by_countries table in the covid_data BigQuery dataset where the population OR country_area value is null.
