Write an instruction explaining how to summarize the key points from a set of lecture notes. Then, summarize the following lecture notes on the history of the telescope in 2-3 sentences:

- Galileo Galilei is credited with building the first telescope used for astronomical observations in 1609.
- Early telescopes had a relatively low magnification and poor image quality due to imperfections in the lenses.
- The reflecting telescope, invented by Isaac Newton in 1668, used mirrors instead of lenses to reflect and focus light, overcoming some limitations of refracting lenses.
- Major advances in telescope technology in the 20th century included the development of radio telescopes to detect radio waves from space and the Hubble Space Telescope launched in 1990, which operates outside Earth's atmosphere.

To summarize key points from lecture notes, read through the notes carefully, identify the main topics or concepts covered, and condense the essential information into clear, concise sentences. The provided lecture notes on the history of the telescope can be summarized as: Galileo Galilei built the first astronomical telescope in 1609, but early telescopes had limited capabilities. Isaac Newton's reflecting telescope in 1668 improved upon lens-based designs, and later advancements included radio telescopes and the Hubble Space Telescope launched in 1990.

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: Hi. Please summarize the benefits of a Roth IRA in one sentence.

This is the paragraph I'd like you to summarize.

What Are the Advantages of a Roth IRA?
While Roth IRAs do not include an employer match, they do allow for a greater diversity of investment options. For individuals who anticipate that they will be in a higher tax bracket when they’re older, Roth IRAs can also provide a beneficial option. In Roth IRAs, you can withdraw your contributions (but not earnings) tax- and penalty-free.
Ultimately, you can manage how you want to invest your Roth IRA by setting up an account with a brokerage, bank, or qualified financial institution.

Response: With a Roth IRA, contributors can invest in more types of investment vehicles than traditional IRAs and because the contribution taxes are paid upfront, the beneficiary can withdraw the funds without taxes or penalties.

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.
