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 following story in a few sentences.
A young Mouse in search of adventure was running along the bank of a pond where lived a Frog. When the Frog saw the Mouse, he swam to the bank and croaked:
"Won't you pay me a visit? I can promise you a good time if you do."
The Mouse did not need much coaxing, for he was very anxious to see the world and everything in it. But though he could swim a little, he did not dare risk going into the pond without some help.
The Frog had a plan. He tied the Mouse's leg to his own with a tough reed. Then into the pond he jumped, dragging his foolish companion with him. The Mouse soon had enough of it and wanted to return to shore; but the treacherous Frog had other plans. He pulled the Mouse down under the water and drowned him. But before he could untie the reed that bound him to the dead Mouse, a Hawk came sailing over the pond. Seeing the body of the Mouse floating on the water, the Hawk swooped down, seized the Mouse and carried it off, with the Frog dangling from its leg. Thus at one swoop he had caught both meat and fish for his dinner.
Response: A mouse was running along the bank of a pond in search of an adventure when he came upon a frog. The frog tied his leg to the mouse's leg with a tough reed to help him swim in the pond. Soon, the mouse wanted to go back to shore but the treacherous frog pulled the mouse underwater and drowned him. Before the frog was able to untie his leg, a hawk spotted the mouse floating on the water and swooped down, carrying both the mouse and the frog away for dinner.

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.

Describe the water cycle and its stages.
user
The water cycle, also known as the hydrologic cycle, is the continuous movement of water on, above, and below the surface of the Earth. It includes several stages: Evaporation (where water changes from liquid to vapor), Condensation (where water vapor cools and forms clouds), Precipitation (where water falls back to the Earth as rain, snow, sleet, or hail), and Collection (where the fallen water collects in oceans, rivers, lakes, and the ground, eventually restarting the cycle).
