Completing his resemblance to a man who was sitting for his portrait, Mr. Lorry dropped off to sleep. The arrival of his breakfast roused him, and he said to the drawer, as he moved his chair to it:

“I wish accommodation prepared for a young lady who may come here at any time to-day. She may ask for Mr. Jarvis Lorry, or she may only ask for a gentleman from Tellson’s Bank. Please to let me know.”

“Yes, sir. Tellson’s Bank in London, sir?”

“Yes.”

“Yes, sir. We have oftentimes the honour to entertain your gentlemen in their travelling backwards and forwards betwixt London and Paris, sir. A vast deal of travelling, sir, in Tellson and Company’s House.”

“Yes. We are quite a French House, as well as an English one.”

“Yes, sir. Not much in the habit of such travelling yourself, I think, sir?”

“Not of late years. It is fifteen years since we—since I—came last from France.”

“Indeed, sir? That was before my time here, sir. Before our people’s time here, sir. The George was in other hands at that time, sir.”

“I believe so.”

“But I would hold a pretty wager, sir, that a House like Tellson and Company was flourishing, a matter of fifty, not to speak of fifteen years ago?”

“You might treble that, and say a hundred and fifty, yet not be far from the truth.”

“Indeed, sir!”

According to the immemorial usage of waiters in all ages.
Response: Mr. Lorry's breakfast arrived, and he asked that the hotel make accommodations for a young woman who would arrive today and that he be told when she arrived. He and the waiter then talked briefly about the success and history of Tellson and Company.

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.
