Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize this info. Have the last sentence involve Andy Warhol. 

One of the types of paint for art you’ll often spot in a market is acrylic paint. Acrylic paint is the most common of the paint types. It is a favorite for many artists because it is cost-effective and often comes in convenient packaging. Most stores sell a wide selection of acrylic paint colors in single tubes or packs. Another bonus is that it is non-toxic, which makes it a great option for kids too!

Acrylic paint is water-based. It is a mixture of pigment with an acrylic polymer emulsion for its binder. Because of its materials, it sticks to most surfaces, such as canvases, woods, and metals. It also dries faster than most types of paint, which makes it convenient for artists who don’t like to wait. Artists can also mix water with acrylic paint, which can dilute the thick paint and make it resemble watercolor.

One of the most famous artists who liked to use acrylic paint is Andy Warhol. His famous painting, Marilyn Diptych, is an example of acrylic paint on canvas.
Response: Acrylic paint is common, as it is cost-effective, convenient, non-toxic, quick-drying, and comes in many colors. It's a water-based mixture of pigment with an acrylic polymer binder, making it stick to canvas, wood, metal, and many other surfaces. Andy Warhol often used acrylic paint, including for his work, Marilyn Diptych.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize this info. Mention the role of the ozone layer at the end. 

The ozone layer is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone (O3) and is found at about 10 to 30 kilometers above Earth. The layer is thicker over the poles and thinner near the equator. This layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. The protection provided by the ozone layer is crucial for life on Earth. It prevents most of the UV-B rays from the sun from reaching the surface, which can cause skin cancer and cataracts in humans and damage to plants.

In the late 20th century, scientists discovered that the ozone layer was being depleted by chemicals like chlorofluorocarbons (CFCs). These chemicals were widely used in refrigerants, aerosol sprays, and other industrial applications. The global response to the issue was the Montreal Protocol agreement in 1987, which aimed to phase out the production of numerous substances that are responsible for ozone depletion. The protocol is considered one of the successful milestones in global environmental agreements.

The ozone layer, a region in Earth's stratosphere, was discovered by Fabry and Buisson in 1913. It absorbs most of the Sun's UV radiation, which is crucial for protecting life on Earth. Depletion of this layer by chemicals like CFCs led to the Montreal Protocol in 1987, aimed at reducing harmful emissions. The ozone layer prevents dangerous UV-B rays from reaching Earth's surface.
