Assumes we know exactly what the query is trying to do. The query executes correctly (as we told it to) so why is there something wrong? How are we expected to guess what it should do at a specific step? Also one of the questions assumes we know what is "legacy SQL".

phrasing of questions was unclear. the data set does not have descriptions. it is unclear what total_transactions actually mean in the row. some questions are asking for number of products and there's a column called hits_product_productQuantity instead but the questions are using total_transactions (confused). there's one suggested answer that's incomplete.
