It may seem like animal shelter is the answer, but those words are apart of a subordinate clause which the sentence could easily go without.
There are three correct answers here:
1. The time of day during which the story takes place
2. The city in which the story takes place
3. The atmosphere or mood of the place.
Characters exist in the setting but aren't part of it in the same way we live on Earth but aren't part of the Earth's composition.
The following is an exerpt from “Finding The Titanic“
(from Planet-Science.com)
”The traditional way to search for wrecks was to use sonar. Sonar uses sound to detect objects underwater. As well as using sonar, Ballard searched for the Titanic's trail of debris. He estimated that it would be over 2km long. Ballard had just 12 days to find it, in an area of ocean five times the size of New York.
To find the trail, Ballard used a deep-sea vehicle called Argo. Argo had lots of cameras and was towed behind the ship. Argo floated just above the sea floor, 2.5 miles down in the cold, dark Atlantic.
After days of searching, Ballard found the trail. He knew the currents would take the trail northwards. Ballard followed the trail and sailed right up to the Titanic!”
Answer:
A woman has three daughters. The older two have no luck at all but the youngest, Nella, is as usual lovely and talented and more or less perfect. She is having a secret affair with a handsome prince who lives many miles away. The two lovers build a glass tunnel that runs under the ground—from the prince’s castle into the princess’s bedroom, so that they might “joy together” without the mom’s knowing it. Every night the prince runs through the tunnel naked to spend time with his young princess.
Nella’s two sisters, who are ugly and evil, learn of the affair and smash the glass tunnel. That night the prince is running so fast to reach his young lover that he doesn’t see the broken glass and the skin all over his body is cut. Because the glass that cut him was enchanted his wounds will not heal. The prince’s father vows that the woman who can find a remedy for the enchanted wounds will be the prince’s wife and if a man heals him he will be given half the kingdom.
Nella is heartbroken upon hearing of her mortally wounded prince, and goes out disguised to at least see him before he dies. Luckily, she overhears two ogres telling each other that the only thing in the whole world that will heal the prince is to smear the fat from their own bodies all over the prince. Nella, pretending to be lost in the woods, begs the ogres to let her into their house. The ogre husband, fancying a bit of human flesh, lets her in eagerly but sadly he drinks so much alcohol that he passes out before he gets to eat her.
Nella quickly gets to work and slaughters him then collects all the fat from his body in a bucket. She makes her way to the prince’s palace. She smears the fat into the prince’s wounds and he is healed as if by magic, then she reveals her identity and the marriage is swiftly arranged. And her sisters? They are burned alive in typical fairy tale fashion, “so that like unto leeches they should purge their blood in the cinders of their wickedness and envy.”
