关于“从 BigQuery 数据中挖掘数据洞见：实验室挑战赛”的评价

I spent more than an hour on Item 2 and couldn’t get any further. SELECT count( distinct subregion1_name) AS count_of_states FROM `bigquery-public-data.covid19_open_data.covid19_open_data` WHERE country_name = 'United States of America' AND subregion1_name IS NOT NULL AND cumulative_deceased IS NOT NULL AND cumulative_deceased > 100 AND date = '2020-06-25'
