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: Explain in two sentences how the author feels about pico de gallo. 


Please use the following source text: 

Do you love pico de gallo like I do? It’s a classic Mexican tomato dip (or sauce) that adds a fresh, healthy, low-calorie boost of flavor to just about any Mexican meal.

When I was little, I piled pico de gallo on my tortilla chips at our nearby Mexican restaurant and called it dinner (refill, please). I didn’t fully appreciate pico de gallo’s wonder, though, until my family traveled to Mexico one summer when I was in college.

We stayed at an all-you-can-eat resort, which meant all-you-can-eat pico de gallo. Their pico de gallo was super fresh and utterly irresistible, and I piled it onto every single meal. Eggs! Tortillas! Beans! Spaghetti, even! Why not?
Response: The author of this text really loves Pico de Gallo. They fully realized how much they liked Pico de Gallo when they traveled to Mexico in college and put it on everything they ate.

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.
