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: From the following article, sum up what the writer is talking about.

Here is the article I mentioned:
Dear Annie: I’ve seen lots of parents (or babysitters) gabbing on the phone as they push strollers or baby carriages. The tots are getting no attention. Once, I saw a large dog, unleashed and apparently unaccompanied, dash up to a youngster in a stroller. Happily, the dog meant no ill and simply gave the child a big, slobbery kiss. And the stroller’s pusher? She missed the entire incident.

She also missed -- as they all do -- the fun of watching the baby’s reactions to the sun and sky and trees and people. And dogs, too. But the cellphone-addicted parents are oblivious. Why isn’t bonding with their kids more important than bonding with their phones? -- Kids Are Better Than Phones

Dear Kids Are Better Than Phones: Being in the moment and drinking in all of life’s beautiful experiences is something that should be treasured for everyone. And for parents and guardians, their children’s safety is also at risk when not properly monitored.
Response: While pushing strollers, the writer has witnessed many caregivers busy talking on their phones instead of interacting with the young child. They question why it seems that caregivers find their phones more important than bonding with young kids. These caregivers are missing little moments and could potentially be putting the child’s safety at risk because they are distracted.

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.
