Video Summary

The athlete has a collection of 2 gold and 5 silver medals, numbered 1 to 7. Each photo shows exactly one gold medal, so each photo with multiple medals must have only one gold. By testing each possibility:<br /><br />1. When 1 is gold, there's no consistent second gold to satisfy all photo conditions.<br />2. When 2 is gold, likewise, no consistent second gold can fulfill the conditions.<br />3. When 3 is gold, making 6 the other gold satisfies all conditions.<br /><br />Thus, the gold medals are numbered 3 and 6. The sum of their numbers is 9. The answer is C.
