Interrogative mood because it asks a question.
This story “Jane Eyre” written by Charlotte Brontë, relates about how the orphan Jane’s life evolves and highlights into her marriage to Mr. Rochester, her former boss she fell in love with. She was thinking to leave with St. John to India, but at night she heard Rochester’s voice calling her through the moors.
Question: How does Jane know to leave St. John and go find Rochester?
Answer: She hears Rochester's voice from afar.
I think its
“They” is cleaning up their garbage mess so that the neighborhood black bear won’t make chaos
Hope this is correct.
