 ### Q6: How many social shares meet complex multi-stage filtering criteria?
+
 **Question**: What is the count of sharing actions from iPhone mobile users on specific social networks, within common timezones, participating in seasonal campaigns, with high screen resolutions and closely matched UTM parameters?
 **Important Query Properties**: Simple filter with high-selectivity, Costly string matching, A large number of filters with high overhead are positioned relatively later in the process

+### Q7: Device Resolution and Refresh Behavior Analysis
+
+**Question**: Identify the top 10 WatchIDs with the highest resolution range (min/max "ResolutionWidth") and total refresh count ("IsRefresh") in descending WatchID order
+
+**Important Query Properties**: Primitive aggregation functions, group by single primitive column, high cardinality grouping
+
+```sql
+SELECT "WatchID", MIN("ResolutionWidth") as wmin, MAX("ResolutionWidth") as wmax, SUM("IsRefresh") as srefresh
+FROM hits
+GROUP BY "WatchID"
+ORDER BY "WatchID" DESC
