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: Read the following: 

If a Spanish class were to go on an in-country immersion in Spain, they’d be flooded by the sights and sounds of native speakers going about their business. Good times! But that would make a huge dent in everybody’s budget. So why not bring a native speaker to class instead?

Pick somebody who’s outgoing, a natural extrovert who loves interacting with people and doesn’t take himself too seriously. Ask him to prepare a short talk. And he can really talk about anything—so long as he does it in Spanish. He can tell his personal story, talk about his job or share some interesting quirk about his culture.

You may be a native speaker yourself, but count yourself out. Bring some new face to stand in front of the class. (There’s just something more effective about a fresh face.)

Now, please summarize what it says about having a native speaker visit the classroom.
Response: Bringing a native speaker into the classroom can help immerse students in a foreign language. Invite a guest speaker who is outgoing, extroverted, and has something interesting to share. 

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.

The key to effective summarization is to capture the main points of a text while omitting unnecessary details. Read the following passage and summarize the core ideas in 2-3 sentences:

In today's fast-paced world, multitasking has become a common practice. People often juggle multiple tasks simultaneously, such as checking emails while attending a virtual meeting or scrolling through social media while watching a movie. However, research has shown that multitasking can significantly diminish productivity and cognitive performance. When our attention is divided, we are less efficient at completing tasks, more prone to errors, and have difficulty retaining information. Effective time management strategies, such as prioritizing tasks, minimizing distractions, and practicing single-tasking, can help improve focus and productivity.
