Extractive summarization involves selecting and concatenating the most representative sentences or phrases from the original text to form the summary. This approach maintains the exact wording and phrasing of the source material. Its strengths are simplicity, preservation of factual accuracy, and computational efficiency. However, extractive summaries can lack coherence and fail to capture the overall context. Abstractive summarization, on the other hand, involves generating new sentences that express the main ideas in a concise manner. This approach requires a deeper understanding of the text's meaning and the ability to paraphrase and generalize. Abstractive summaries can be more coherent and capture the essence better, but they risk introducing factual errors or omitting important details.

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: I want a summary of the key points in no more than 4 sentences. 

Use this text for the summary:
Both Russia and the United States like to lay claim to the Siberian Husky. The breed was developed by the Chukchi tribe of northeast Asia over 3,000 years ago to help them in their nomadic life as sled pullers. Certainly, the breed has spitz ancestors.

During the Alaskan gold rush, many sled dog races were set up for amusement as well as for checking out working stock. The dogs from the Chukchis proved to be fast runners of great endurance despite their small size.

The fame of the Siberian husky as a racing sled dog was cemented when a team of huskies raced 340 miles through raging blizzards to deliver serum for diphtheria-stricken Nome. The movie "Balto" and the many stories on the same theme have made this breed recognized by people worldwide.

While most of today's Siberian huskies are beloved family pets, many still pull sleds in local races and enjoy ski-joring with their owners.
Response: Russia and the US lay claim to Siberian Huskies, but they were developed by Asia's Chukchi tribe for sled-pulling thousands of years ago. Chukchis' dogs were fast runners in Alaskan gold rush sled dog races, and Siberian Huskies became popular racing sled dogs when they delivered medication over 300 miles in a blizzard. People now recognize the breed from this story and the movie "Balto". Siberian Huskies are pets nowadays but still pull sleds.

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.
