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.

Chinese espionage is becoming more difficult for U.S. companies to track. The Asian country is shifting to targeting internet security services, researchers for Google said in a report Thursday.
The researchers said they recently discovered a new virus targeting the software security company Fortinet. Alleged Chinese hackers used a "back door" to hack the security company's system and upload malicious code to the company's security management tool, according to the report.

"Given how incredibly difficult they are to find, most organizations cannot identify them on their own," Charles Carmakal, chief technology officer at the Google-owned company Mandiant, said in a statement to Axios. "It’s not uncommon for Chinese campaigns to end up as multi-year intrusions."

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.
