for question 2, when i populate the mobility record with this query, my answer is not accepted, and i do not understand why: INSERT INTO covid_data.consolidate_covid_tracker_data ( mobility) SELECT STRUCT( AVG(retail_and_recreation_percent_change_from_baseline) as avg_retail, AVG(grocery_and_pharmacy_percent_change_from_baseline) as avg_grocery, AVG(parks_percent_change_from_baseline) as avg_parks, AVG(transit_stations_percent_change_from_baseline) as avg_transit, AVG( workplaces_percent_change_from_baseline ) as avg_workplace, AVG( residential_percent_change_from_baseline) as avg_residential) AS mobility FROM `bigquery-public-data.covid19_google_mobility.mobility_report` GROUP BY country_region, date i have also tried to insert the date and country_area columns, but there is no column corresponding to country_area column in the target table. i would like to know what i am doing wrong. **UPDATE** when i tried the lab for the fourth time, the questions were changed.
