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: In two sentences, tell me the main points from the news article.

The article in reference:
Eighteen-hundred people were called as potential jurors, and the pool whittled down to 10 men and eight women last week.
All 16 will hear the case, but only 12 will actually take part in deliberations to decide Vallow Daybell’s guilt or innocence. The other six are alternates and will be released from service before deliberations begin. Jurors will not be notified they are an alternate until it is time for deliberations in order to ensure they all stay engaged throughout the trial.
The trial is expected to take up to 10 weeks.
Chad Daybell, seen during a 2020 court appearance, has also pleaded not guilty. Only Vallow Daybell’s trial begins Monday.

Response: The trial of Vallow and Chad Daybell is expected to take up to 10 weeks. Eighteen jurors have already been selected from a pool of 1,800 potentials, and while all eighteen will hear the case, only twelve will be allowed to take part in the decision-making process; the other six are potential alternates.

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.

Outline the key points of Charles Darwin's theory of evolution, in two sentences.

Charles Darwin's theory of evolution posits that all species of organisms arise and develop through natural selection, which increases an individual’s ability to survive and reproduce. This theory emphasizes that favorable traits become more common in successive generations, leading to gradual changes and the evolution of species over time.
