Passage 2: Adapted from "Why the Sun and the Moon Live in the Sky" in Folk Stories from Southern Nigeria, West Africa by Elphinstone Dayrell (1910)

Many years ago the sun and water were great friends, and both lived on the earth together. The sun very often used to visit the water, but the water never returned his visits. At last the sun asked the water why it was that he never came to see him in his house, the water replied that the sun's house was not big enough, and that if he came with his people he would drive the sun out.

He then said, "If you wish me to visit you, you must build a very large compound; but I warn you that it will have to be a tremendous place, as my people are very numerous, and take up a lot of room."

The sun promised to build a very big compound, and soon afterwards he returned home to his wife, the moon, who greeted him with a broad smile when he opened the door. The sun told the moon what he had promised the water, and the next day commenced building a huge compound in which to entertain his friend.

When it was completed, he asked the water to come and visit him the next day.

When the water arrived, he called out to the sun, and asked him whether it would be safe for him to enter, and the sun answered, "Yes, come in, my friend."

The water then began to flow in, accompanied by the fish and all the water animals.

Very soon the water was knee-deep, so he asked the sun if it was still safe, and the sun again said, "Yes," so more water came in.

When the water was level with the top of a man's head, the water said to the sun, "Do you want more of my people to come?" and the sun and moon both answered, "Yes," not knowing any better, so the water flowed on, until the sun and moon had to perch themselves on the top of the roof.

Again the water addressed the sun, but receiving the same answer, and more of his people rushing in, the water very soon overflowed the top of the roof, and the sun and moon were forced to go up into the sky, where they have remained ever since.

Passage 1: Rabbits, Stoats, and Kiwis: The Ecology of New Zealand (2016)

The island nation of New Zealand is unique. Many of its animals and plants are found nowhere else. The kiwi is one of the most famous of these animals. This small, flightless bird dwells on the ground. It has tiny wings with which it is unable to fly. Kiwis belong to the same biological family as ostriches and emus, but they are much smaller than their relatives. Kiwis have round bodies and long beaks, and their brown feathers are very long and thin. Because of this, at first glance, someone who has never seen a kiwi before might think it has fur! 

New Zealand is particularly fond of the kiwi. It is the country’s national bird. New Zealanders are even sometimes referred to as “kiwis.” Unfortunately, the kiwi is in danger due to changes humans made to New Zealand’s environment.

Hundreds of years ago, European colonists decided to bring rabbits from Europe to New Zealand. They wanted to hunt them for food and for sport. Unfortunately, their plan succeeded too well. In Europe, other animals in the food chain eat rabbits. This keeps their population in check. In New Zealand, though, no animals ate rabbits. So, their population grew to an enormous size. There were way too many rabbits! 

The colonists tried to fix the problem by bringing another animal to New Zealand. Since none of New Zealand’s animals ate rabbits, the colonists imported one from Europe that did: the stoat. Stoats are small, carnivorous mammals similar to weasels. They eat rabbits, as well as birds and their eggs. Bird scientists warned the colonists to reconsider their plan, but the plan went forward—to the kiwi’s detriment.

New Zealand’s islands historically lacked predatory mammals. Because of this, kiwis’ flightlessness never put them at a huge risk of being hunted and eaten. This was the case until the stoats were released. The stoats began to eat the kiwis and their eggs in huge numbers. The kiwis had no way of protecting themselves from the stoats. As a result, their population plummeted. 

To this day, stoats threaten the kiwi population in New Zealand. To protect native wildlife, residents have to tried to use various methods of trapping and hunting to limit the size of the stoat population. Certain areas have also been fenced in to keep stoats away from native birds like the kiwi.

To function, environments maintain a careful equilibrium between predators and prey. Altering this balance purposely or accidentally can have serious consequences.
