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: In short, why does the article say second terms are terrible?

Warning: second terms are terrible. Now, the bad news for Democrats. Beginning with George Washington, second terms are a litany of troubles. No modern president has had a good time of it. Work backwards: George Bush’s second term started with Katrina and ended in financial disaster; Clinton met Monica and was impeached; Reagan ran into Iran Contra, saw his approval plummet, lost the Senate, had a bout with cancer, and grew deeply despondent. Richard Nixon resigned. Eisenhower suffered a heart attack, a stroke, and became enmeshed in civil rights. FDR lost his coalition in Congress, saw the economy falter, and was humiliated when he tried to intervene in the midterm elections. Of course, history is not destiny. But it offers second-termers a gloomy warning. It gets only harder and the burdens of office take a personal toll.
Response: In short, second terms have been historically tough for a lot of past presidents. Many of the events were out of the control of the president at the time, but nevertheless, they ran into problems that impeded the second term of their presidency. Events such as natural disasters, scandals, sickness, economic collapse, and more have all been issues during the second term of presidencies.

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 steps involved in the water cycle. The water cycle consists of several key stages: evaporation, condensation, precipitation, and collection. During evaporation, water from oceans, rivers, and lakes turns into vapor due to heat from the sun. This vapor rises into the atmosphere and cools down, forming clouds in a process called condensation. When these clouds become heavy, they release water in the form of precipitation (rain, snow, sleet, or hail). The precipitated water is collected in bodies of water, such as rivers, lakes, and oceans, and the cycle begins anew.

The water cycle includes evaporation, condensation, precipitation, and collection. Water evaporates due to the sun's heat, forms clouds through condensation, falls as precipitation, and is collected in bodies of water, restarting the cycle.
