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.

Manage Stress Levels
Woman Stressed Tinnitus Cause
As we mentioned before with the ‘vicious cycle’, tinnitus has a strong link to stress. Despite this, some people are surprised to find that stress management methods equip them with a way to control their tinnitus for life.

Stress can exacerbate tinnitus and trigger symptoms. Prolonged periods of stress can and make the ringing sound louder for some individuals.

People with tinnitus often find that their stress threshold is lower than it used to be before tinnitus. This means that it is particularly important for tinnitus sufferers to understand their stress levels and work to improve their quality of life and prevent the exacerbation of other mental health issues. 

Therefore, a possible solution in the remedies for tinnitus is to find hobbies and activities that you find relaxing! What acts as a stress-releaser won’t be the same for everyone, so take some time to figure out what works for you. Tinnitus is often a mysterious and confusing condition, so whether you’re helped by activities such as painting, reading, going to the cinema, taking part in sport, and meeting up with a friend, or more unconventional hobbies, carve out some ‘me time’ in your schedule. 
Response: Since tinnitus is linked to stress, you should try stress management methods like relaxing hobbies.

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.
