What does the text say about the functions of vitamins in the human body?

Vitamins are essential nutrients that the body needs to function correctly. They play various roles in bodily processes. For example, Vitamin C is crucial for the repair of tissues, Vitamin D aids in bone health by helping the body absorb calcium, and Vitamin A is important for vision and immune function. The body cannot synthesize most vitamins in sufficient quantities, so they must be obtained from the diet. Deficiencies in specific vitamins can lead to health problems and diseases.

Vitamins are essential nutrients needed for various bodily functions, such as tissue repair (Vitamin C), bone health (Vitamin D), and vision and immune function (Vitamin A). They must be obtained from the diet as the body can't produce most vitamins sufficiently. Deficiencies can cause health issues.

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: Briefly tell me what this text says about Greece. 

Greece has the longest coastline in Europe and is the southernmost country in Europe. The mainland has rugged mountains, forests, and lakes, but the country is well known for the thousands of islands dotting the blue Aegean Sea to the east, the Mediterranean Sea to the south, and the Ionian Sea to the west.

The country is divided into three geographical regions: the mainland, the islands, and Peloponnese, the peninsula south of the mainland.
Response: Greece is the southernmost country in Europe and has the longest coastline. Its mainland includes mountains, forests, and lakes, while thousands of islands surround it in the Aegean, Mediterranean, and Ionian Seas. Greece also includes the Peloponnese, a peninsula to the south.

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.
