Agatha Christie's travels with her archaeologist husband inspired her to write several mystery novels; travelers to Egypt can still stay at the Old Cataract Hotel, the model for the hotel in one of Christie's most famous books.
A) Agatha Christie's travels with her archaeologist husband inspired her to write several mystery novels
B) Agatha Christie used her travels with her archaeologist husband to inspire several mystery novels
C) Because her husband was an archaeologist, Agatha Christie was able to use their travels as inspiration for several of her mystery novels
D) Together with her archaeologist husband, Agatha Christie was inspired to incorporate their travel into several of her mystery novels
E) Agatha Christie's travels with her archaeologist husband served as inspiration for several of her mystery novels
The original answer is E. Can someone explain to me the possessive pronoun rules regarding antecedents. Maybe I'm misinterpretting the Possessive Poison rule from the SC guide, but I thought since the subject was Agatha Christie's travels that "her" could not refer to Agatha Christie. Any help would be greatly appreciated.
