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: Give me a one sentence summary of the main point of the following excerpt:

Livestreamed events
Pre-Covid, online events were reserved for the technologically savvy. Today, we’re all early adopters: watching online live performances, attending virtual conferences, taking yoga classes via Zoom — suddenly, a world of choices and opportunities can be found on our touchscreens.

While some may lament the digitization of things that used to be done IRL, many of these changes have brought new access and equity to these activities. Seniors in remote areas can now take online exercise classes. Telehealth sessions are bringing medical care to residents of small islands. And for those of us who don’t have easy access to world-class cultural productions, there are now livestreamed performances everywhere you look.

Response: Because of COVID, things like attending virtual conferences, taking athletic classes via ZOOM, and even using Telehealth for healthcare have become easily accessible to the average person.

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.

Summarize the main points discussed in the following paragraph about the challenges of effective summarization:

While summarization is a crucial skill, it's not without its challenges. Firstly, identifying the true essence of a text requires a deep understanding of the subject matter and the ability to discern between central and peripheral information. This can be particularly difficult when dealing with unfamiliar or technical topics. Additionally, effective summarization demands objectivity and impartiality, as personal biases or preconceptions can skew the representation of the original material. Furthermore, striking the right balance between concision and completeness is a delicate art – a summary that is too brief may omit crucial details, while an overly lengthy one defeats the purpose of summarization. Finally, summarizing complex arguments or intricate narratives poses an additional challenge, as capturing the nuances and intricacies of the original text can be arduous.
