A parameter query allows the user to input a parameter (in this case, the name of the cooking demonstration) before the query runs. This will allow Carlos to filter the results of the query based on the specific cooking demonstration he is interested in. Top values query is used to return a specific number of records with the highest or lowest values, crosstab query is used to calculate and summarize data by cross-tabulating rows and columns, and a pattern match query is used to search for records based on a specific pattern or string of characters. None of these options would be useful in allowing Carlos to input the name of the cooking demonstration before running the query.
