Recycling plays a vital role in protecting the environment. By reusing materials such as paper, plastic, and glass, we can significantly reduce the amount of waste that ends up in landfills. This process also helps conserve natural resources and reduce pollution, as manufacturing from recycled materials uses less energy and water than producing from raw materials. Recycling creates jobs in the collection, processing, and selling of recycled goods. Many cities that have implemented effective recycling programs have seen economic and environmental benefits.
Question: What is the main idea of the paragraph?
Answer: Recycling helps protect the environment and economy by reducing waste and creating jobs.
Many people underestimate the importance of sleep in their daily lives. Sleep is not only a time to rest but also a time for the brain and body to recover.

Experts recommend that adults sleep for at least seven to eight hours each night. Developing a healthy sleep routine can improve overall well-being.

Photosynthesis is a process by which green plants make their own food. This process takes place mainly in the leaves, using a green pigment called chlorophyll. When sunlight hits the leaves, chlorophyll absorbs the light energy. Plants use this energy, along with carbon dioxide from the air and water from the roots, to produce glucose. This sugar is then used by the plant for growth and energy. Oxygen is also produced during photosynthesis and is released into the air. This process is vital for life on Earth.
Question: What is the main idea of the paragraph?
Answer: Photosynthesis is the process plants use to make food and produce oxygen.

Polar bears are facing serious challenges due to climate change. As global temperatures rise, sea ice—the primary habitat for polar bears—melts earlier and forms later each year. This limits the bears’ ability to hunt seals, which are their main food source. As a result, many polar bears are becoming thinner and are having fewer cubs. Scientists have also observed that some bears must swim longer distances between ice patches, increasing their risk of drowning. These changes not only threaten the survival of polar bears but also indicate larger environmental problems.
Question: What is the main idea of the paragraph?
Answer: Climate change is threatening polar bears by reducing their habitat and food supply.
Climate change is a global issue that affects weather patterns, sea levels, and natural habitats. Human activities such as burning fossil fuels and cutting down forests release greenhouse gases that trap heat in the atmosphere. As a result, temperatures rise, ice melts, and extreme weather events become more common. These changes threaten wildlife, agriculture, and human settlements. Scientists urge governments and individuals to take action by reducing emissions, switching to renewable energy, and protecting ecosystems.
Question: What is the main idea of the paragraph?
Answer: Climate change caused by human activities has serious global consequences.
