Bees play an important role in the environment. As they travel from flower to flower collecting nectar, they spread pollen between plants. This process, called pollination, helps plants produce fruits and seeds. Many of the foods people eat, including apples, strawberries, and almonds, depend on pollination. Without bees and other pollinators, food production would become much more difficult.
What is the main idea of this passage?
Bees are important because they help plants grow and produce food.

The deep ocean is one of the darkest places on Earth. Sunlight cannot reach most of these depths, so many animals have developed unusual ways to survive. Some creatures produce their own light through a process called bioluminescence. Others have large eyes to help them see in low-light conditions. These special adaptations allow deep-sea animals to find food, avoid predators, and survive in an extreme environment.
What is the main idea of this passage?
Deep-sea animals have special adaptations that help them survive.
Many animal species around the world are at risk of becoming extinct. Habitat destruction is one major reason animals become endangered. When forests are cut down or wetlands are drained, animals lose the places where they find food and shelter. Pollution and illegal hunting also threaten wildlife populations. Scientists and conservation groups work to protect endangered animals by creating wildlife preserves and enforcing laws against hunting.
Which detail best explains why habitat destruction is dangerous to animals?
Animals lose places where they find food and shelter.
Plastic pollution has become a serious threat to the environment. Millions of tons of plastic enter the oceans each year, where animals may mistake it for food. Sea turtles, birds, and fish can become injured or die after swallowing plastic. Although plastic is convenient, people should reduce their use of disposable plastic products. Reusable water bottles and shopping bags are simple ways to make a difference.
What is the author's perspective about plastic pollution?
People should take steps to reduce plastic pollution.
Many cities are trying to implement new recycling programs to reduce waste. Instead of simply discussing ideas, city leaders are putting these plans into action by adding more recycling bins and creating community education programs.

More people had opportunities to learn how to read, and information could spread across Europe more quickly.
Which detail best supports the idea that the printing press made books more accessible?
Books became more available to ordinary people.
Playing team sports teaches children more than how to score points or win games. Athletes learn to communicate, cooperate, and trust one another. When a team loses, players have an opportunity to practice handling disappointment and working harder. These lessons can help children become successful in many areas of life. Although individual sports have benefits, team sports offer important opportunities to develop social skills.

Wetlands are areas where water covers the soil for at least part of the year. These environments provide homes for many different plants and animals. Wetlands also act like natural filters by trapping pollution and improving water quality. During heavy rainfall, they absorb extra water, which can help prevent flooding in nearby communities. Unfortunately, many wetlands are being destroyed to make room for buildings and roads.
What is the main idea of this passage?
Wetlands are important environments that provide several benefits.
Trees provide many benefits to the environment. They absorb carbon dioxide from the air and release oxygen, which humans and animals need to breathe. Their roots hold soil in place and help prevent erosion during heavy rain. Trees also provide shade that can lower temperatures in neighborhoods and cities. In addition, forests provide habitats for thousands of animal species.
Which detail supports the idea that trees help protect the environment?
Tree roots hold soil in place and help prevent erosion.
National parks protect some of the most beautiful and important natural areas in the country. These parks provide safe habitats for wildlife and allow visitors to experience nature.
