Hi Audrey, thanks for the question!

Only two of the variables could be last because both F and S come before T, meaning that neither F nor S could be last.

And P comes before G, meaning that P cannot be last. This leaves only T and G to be last.

I hope this helps. Please let me know if you have any other questions or would like me to elaborate further!
