Natural selection is the process by which organisms with traits better suited to their environment are more likely to survive and reproduce. This results in the gradual evolution of species over time as advantageous traits become more common in a population. The driving force behind natural selection is competition for resources, such as food, shelter, and mates. As individuals with beneficial traits are more successful in these competitions, they pass on those traits to their offspring, leading to the evolution of populations.

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: Recap this text for me in 4 sentences. 

Most of the planets in our solar system – and some asteroids – have moons. Earth has one moon. We call it "the Moon" because for a long time it was the only one we knew about. Many languages have beautiful names for our Moon. It is "Luna" in Italian, Latin, and Spanish, "Lune" in French, "Mond" in German, and "Selene" in Greek.

Our Moon is like a desert with plains, mountains, and valleys. It also has many craters, holes created when space rocks hit the surface at a high speed. There is no air to breathe on the Moon.

The Moon travels around the Earth in an oval-shaped orbit. Scientists think the Moon was formed long, long ago when Earth crashed into a Mars-sized object.
Response: Earth - like many planets and asteroids - has a moon (The Moon). It's called "Luna", "Lune", "Mond", and "Selene" in various languages. The Moon is cratered, mountainous, and desert-like with no air to breathe, and it orbits Earth. It's believed that Earth crashed into a large object long ago, and that created the Moon.

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.
