The correct answer is: Summary
<span>If you only selected fields from a single table in the first screen, then when you click the “Next >” button to continue, you will only need to provide the query with a name and then click the “Finish” button to finish creating the query. If, however, you picked data fields from two or more related tables, then when you click the “Next >” button, you will instead view a second screen which asks if you would like a “Detail” or “Summary” query. You can select the option button for the type of query that you wish to create. If you select “Summary,” then you will be able to click the “Summary Options…” button to open the “Summary Options” dialog box. In this dialog box, you can select what type of summary to perform over a selected field. Make your selections, and then click the “OK” button to return to the “Simple Query Wizard.”</span>
