Rachel I think you'll just need to do width: 100% on the card class as shown in here. Otherwise Daniyal M. suggestion for creating more cards will work, just be sure to follow the same patterns as previous cards.
Daniyal M. I did the copy and paste method for the card but hadn't changed the combo class to card-5 so couldn't see it. I've now been able to change the content on card-5 but still can't view it in the interaction.
Matt J. Do I now need to make changes to the interaction to trigger card-5? Changing the card width worked. To achieve the same height on the cards I added lines in the paragraph.
