This lab seems like it needs more testing, I got some unexpected results from some queries, and had trouble accessing the public-datasets resource using the URL provided.

This is by far the most problematic lab I found in Qwiklabs. - The Natural Language API demo now (2020-07-22) shows *very* different values than the ones expected by lab. The questions need some serious update. - The 1st. progress checker didn't recognize my queries, even though they were correct. I could proceed only after entering the suggested possible solutions. - Why should one use DISTINCT in the SQL that creates the sales_by_sku_20170801 table? There is already a GROUP BY for the only non-aggregate column.
