Section 6 - House plants
The dead house plants are in the Hotel lobby. The dead house plants are scenery and plural-named. The description is "The leaves have fallen off the plants and are now only dead branches. They're beyond resuscitation."
Understand "plant" and "houseplants" and "leaves" and "leaf" and "brances" and "branch" as the dead house plants.
Instead of doing anything other than examining with the dead house plants:
say "The plants are not important."
