One question assumes the user has seen Legacy SQL before, and would know how to identify it. If a person is inexperienced enough to need this lab, what are the chances they have history with Legacy SQL? One question expects you to answer that "page title" is missing from the query, when "page title" was never specified in the requirements for the query. One question expects you to answer "Large GROUP BYs hurt performance..." but the table only has ~56k records. 56k records meets google's definition of "large?" One question asks you to identify a logical problem with a query, without first defining what the query is supposed to do. From a pedagogical standpoint, this is a terrible lab.
