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: Please summarize this text from a review of the 'Sonic the Hedgehog' movie in just a couple of sentences.

Here is the text.

Sonic also famously boasts one of the largest and strangest online fandoms, and the movie makes nods to several memes, none of which distract from the plot. The film is in on the joke. It feels like a friend made it.

And that’s the difference between this and so many other video game films. Tyson Hesse, a Sonic fan artist who eventually began official work on the franchise, was brought in to salvage the film from the backlash of the horrifying original design Paramount Pictures proposed.

Redesigning Sonic was not only smart, it was necessary. The original design was so terrible, it would’ve sunk this otherwise heartwarming and expertly crafted film. Sonic fans have long been victimized by a gauntlet of mediocre-to-terrible video games. The memes have been a way to cope. It’s no surprise that Sonic Mania, a 2018 fan-led Sega game to which Hesse contributed, remains one of Sonic’s few bright spots this century. Adding a messy Sonic movie to the lineage of bad games and tie-ins would have been tragic.

Speaking of Sonic Mania, sharp-eared Sonic fans will hear some familiar tunes. Yes, you’ll even hear the piano jazz stylings of Jon Batiste, band leader for “The Late Show with Stephen Colbert” and lifelong Sonic fan
Response: Sonic has a large online fanbase, and that fanbase is largely to thank for the film's success considering the studio had to completely redesign Sonic following backlash to their original proposal. The original proposed design was so poor it would have doomed the film as a whole, adding it to a long lineage of bad video games and tie-in projects in the Sonic legacy.

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.
