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: Summarize the situations when a person may benefit from Elderberry supplements in one short sentence.

What are the benefits of elderberry?
Like many herbal supplements, elderberry can provide nutrients to your body while boosting its immunity powers. The reason why elderberry is so great at helping your body's immunity is because elderberries contain antioxidants called anthocyanins and flavonoids. WebMD explains that flavonoids "seem to help reduce swelling, fight inflammation, and boost the immune system."


Elderberry's specific benefits can include the following:


Lessening cold and flu symptoms, like upper respiratory symptoms, if taken in the first 48 hours of a virus
Reducing inflammation and swelling
Easing constipation due to the anthraquinones in elderberry
Boosting immunity and health to possibly prevent future illness

Note: These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
Response: Persons may benefit from Elderberry supplements if they have cold or flu symptoms, a lessened immune system, inflammation or swelling, or are constipated.

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.
