May Day is a public holiday usually celebrated on 1 May. It is an ancient Northern Hemisphere spring festival and a traditional spring holiday in many cultures. Dances, singing, and cake are usually part of the festivities. In the late 19th century, May Day was chosen as the date for International Workers' Day by the Socialists and Communists of the Second International to commemorate the Haymarket affair in Chicago. International Workers' Day can also be referred to as "May Day", but it is a different celebration from the traditional May Day.

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.

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. During photosynthesis, these organisms take in carbon dioxide and water from the environment and release oxygen as a byproduct. This process occurs in the chloroplasts within plant cells and is crucial for converting light energy into chemical energy.
