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: As a bullet point outline, summarize the contents of this text.

Last week, shortly after a Wii review unit arrived at Forbes.com's office, I set it up in a conference room to test it out. A colleague and I booted up Wii Sports, a collection of simple sports games that comes bundled with every console. It wasn't long before we were completely immersed in Wii Tennis. The simple mini-game replicates an actual tennis match as well as any I've ever seen: Since you're actually swinging the remote like you would a racket, you can hit with varying force or apply spin to the ball, depending on how you move your body.

Within minutes, we'd drawn a crowd, and only a short while after that, most of the editorial staff was packed into the conference room, laughing, enjoying the show and pushing for their turn at the remote. It was the first time since the original Nintendo Entertainment System came out in 1985 that videogaming felt like a party experience--not just because it was new, and worth gawking at, but because the experience is so much more physical, like Charades or Twister, and spectators can enjoy as much as the players.

After the hard-core gamers got their turns, less videogame-savvy editors took a shot, too. And it was here where the intuitive motion control system really proved its worth. There's no sequence of arcane button combinations required to throw a baseball: You just wind up and mime an actual throw. Suddenly, videogames are fun for everyone--old or young, male or female, regardless of prior gaming experience. I lost count of how many times I heard non-gamers say, "Wow, I want to get this."

The other phrase I heard a lot was something to the effect of, "There's no way I'm shelling out all that cash for a PlayStation 3." Sony's new game console, which debuts Nov. 17 in the U.S., will retail for $500 or $600, depending on whether you buy a basic setup or the premium version, which comes with a bigger hard drive, built-in Wi-Fi and a flash memory card reader. Similarly, Microsoft's Xbox 360, which debuted in November 2005, now retails at $300 or $400.

Compare that to the Wii's $250 price tag, and Nintendo's already got a leg up in the upcoming console war. By concentrating on innovating through game play, and ignoring its competitors' most high-tech features--super-powered processors, support for high-definition televisions and DVD formats--Nintendo has not only been able to keep its costs down, but it's hit upon the single thing that sets apart an entertainment device most: It's fun.
Response: Here is the bullet point summary you asked for:

- The Wii Sports Tennis game is immersive and fun
- The motion-based controller means users can swing as if they are holding a real tennis racket
- The physical experience allows for an enjoyable experience for both players and spectators
- The controls don't require complex button sequences meaning that everyone can enjoy regardless of gaming experience
- Sony's PS3 retails for around $500 and the Xbox 360 retails for between $300-400
- The Wii retails at just $250
- The biggest advantage of the Nintendo Wii is that it's fun

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.
