A Data Engineer is working to optimize the performance of end-users' queries about automobile shipment data for a portal web application that generates dashboards for different clients. An internal team queries the information using order_date as a WHERE condition; the ingestion and natural clustering are performed in this column. However, the application recovers data using the client_id, warehouse, product_id, and destination_city. The Engineer needs to create materialized views with different cluster keys, and must choose two columns combined with client_id to optimize the first cluster key. Which statements will provide all the information needed to select the MOST effective combination of columns to cluster? (Choose two.)
