In what part of the novel are you speaking?
I think it's the first sentence because a noun phrase contains is or contains the subject and Hikers is the subject.
Answer:
1. In the second sermon, Paneloux refers to the New Testament by comparing the suffering of the "earthly" father at the death of his child with God's suffering at the death of Christ. Paneloux says that the cross is the symbol, face to face, with the suffering child.
2. Paneloux dies, clutching a crucifix. His death, however, is less violent than a typical plague death, and his case is recorded as a "Doubtful case."
3 Soon thereafter, Paneloux falls ill, but he refuses to consult a doctor. His symptoms do not conform to those of the plague, so when he dies, Rieux marks him as a "doubtful case."
In the story, it's written that she has drowned a young girl. But it's not an actual winning, rather than it convey that the woman usually see a young girl in the reflection but as she got older, she couldn't see the beautiful reflection anymore.
So i think the most appropriate answer would be : Realized that she must forget the past
hope this helps
