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: Summarize this article on pancreatic cancer in a few sentences. 


Facing a new reality of having one of the toughest-to-treat cancers can indeed be overwhelming. That’s why it’s so important to make sure your treatment plan is the best possible one for you, say experts. One way to do that is with a second opinion.

The reasons why pancreatic cancer patients seek second opinions are as varied as the patients themselves. “One of the things I pride myself on is spending time with my patients and explaining options,” says gastrointestinal oncologist Allyson Ocean, M.D., Associate Professor of Clinical Medicine at Weill Cornell Medical College of Cornell University, and medical oncologist and attending physician in gastrointestinal oncology, Solid Tumor Division, at New York-Presbyterian Hospital/Weill Cornell Medical Center, New York. “I see a lot of second opinions, but I also encourage my patients to get a second opinion. I’ll give them names. That’s because pancreatic cancer is extremely complex, and patients need to feel comfortable with their treatment plan and the medical professionals who are going to be carrying out that plan. Anything less than that makes it harder on the patient, and none of us want that.”

But there are other equally important reasons to get a second opinion. “Sometimes a patient will come to me for a second opinion simply for reassurance the recommendation they currently have is the same thing that we would do,” says Ocean, adding that’s a fairly common scenario, though in many cases a treatment approach can be “slightly tweaked,” she adds. However, there are some instances in which pancreatic cancer patients are not told about innovative treatments simply because their current doctors weren’t aware of those treatments and they aren’t experts in pancreatic cancer care. “What patients forget sometimes is they have every right to a second opinion, and to consult other experts at any point in time, really,” Ocean states.
Response: Patients seek second opinions after a pancreatic cancer diagnosis for a variety of reasons. One reason is to ensure they feel comfortable with their treatment plan and providers because the disease is complex. Another reason is to find out if there are other treatment options available that a different provider would recommend or that their current doctor is unaware of.

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.

Describe the basic principles of Newton's three laws of motion.

Newton's three laws of motion are fundamental principles that describe the relationship between a body and the forces acting on it. The first law, the law of inertia, states that an object remains at rest or in uniform motion unless acted upon by a force. The second law explains that the force acting on an object is equal to its mass times its acceleration (F=ma). The third law states that for every action, there is an equal and opposite reaction.
