Fun lab and challenging. I would rephrase the last task's first sentence to "find the countries in <table name> without data in either population, country_area, or both. The current phrasing makes it unclear whether it's isolated to the lab table or if it means all countries in general. The international_census_bureau dataset for example contains an additional 40 countries not in the lab table, which means they are "missing" in the lab table, and according to the current wording, would suggest that maybe they need to be included in task 6's query, as they are missing and also don't have population or country_area data.
