Automatic text summarization can be approached using two main techniques: extractive and abstractive methods. Extractive methods involve selecting and concatenating the most important sentences or phrases from the original text to form the summary. This approach leverages statistical and linguistic features to identify and rank the most relevant sentences. Abstractive methods, on the other hand, aim to generate entirely new sentences that capture the essence of the text, much like a human would summarize it. These methods often employ advanced natural language processing and generation techniques, including neural networks and deep learning models. Abstractive summarization is generally more challenging but can produce more concise and coherent summaries.

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: Sum this up for me in one paragraph with 6 sentences. It's about the Tulsa Race Massacre.


Governor James B. A. Robertson had gone to Tulsa during the riot to ensure order was restored. Before returning to the capital, he ordered an inquiry into events, especially of the City and Sheriff's Office. He called for a Grand Jury to be empaneled, and Judge Valjean Biddison said that its investigation would begin June 8. The jury was selected by June 9. Judge Biddison expected that the state attorney general would call numerous witnesses, both black and white, given the large scale of the riot.[120]

State Attorney General S.P. Freeling initiated the investigation, and witnesses were heard over 12 days. In the end, the all-white jury attributed the riot to the black mobs, while noting that law enforcement officials had failed in preventing the riot. A total of 27 cases were brought before the court, and the jury indicted more than 85 individuals. In the end, no one was convicted of charges for the deaths, injuries or property damage.[121]

On June 3, a group of over 1,000 businessmen and civic leaders met, resolving to form a committee to raise funds and aid in rebuilding Greenwood. Judge J. Martin, a former mayor of Tulsa, was chosen as the chairman of the group. He said at the mass meeting:

Tulsa can only redeem herself from the country-wide shame and humiliation into which she is today plunged by complete restitution and rehabilitation of the destroyed black belt. The rest of the United States must know that the real citizenship of Tulsa weeps at this unspeakable crime and will make good the damage, so far as it can be done, to the last penny.[120]
Many black families spent the winter of 1921–1922 in tents as they worked to rebuild. Charles Page was commended for his philanthropic efforts in the wake of the riot in the assistance of 'destitute blacks'.[122]

A group of influential white developers persuaded the city to pass a fire ordinance that would have prohibited many black people from rebuilding in Greenwood. Their intention was to redevelop Greenwood for more business and industrial use and force black people further to the edge of the city for residences. The case was litigated and appealed to the Oklahoma Supreme Court by Buck Colbert Franklin, where the ordinance was ruled unconstitutional. Most of the promised funding was never raised for the black residents, and they struggled to rebuild after the violence. Willows, the regional director of the Red Cross, noted this in his report, explaining his slow initial progress to facilitate the rehabilitation of the refugees. The fire code was officially intended to prevent another tragedy by banning wooden frame construction houses in place of previously burnt homes. A concession was granted to allow temporary wooden frame dwellings while a new building, which would meet the more restrictive fire code, was being constructed. This was quickly halted as residents within two weeks had started to erect full-sized wooden frame dwellings in contravention of the agreement. It took a further two-month delay to secure the court decision to reinstate the previous fire code. Willows heavily criticized the Tulsa city officials for interfering with his efforts, for their role in the Public Welfare Committee which first sought to rezone the "burned area" as industrial, and for constructing a union station in its place with no consideration for the refugees. Then he criticized them again for the dissolution of the Public Welfare Committee in favor of the formation of the Reconstruction Committee which failed to formulate a single plan, leaving the displaced residents prohibited from beginning reconstruction efforts for several months.[123]
Response: In the aftermath of the Tulsa Race Massacre, a Grand Jury investigated the issue over twelve days, ultimately ruling that the riot had been the result of black mobs. Though law enforcement was also implicated in failing to prevent the riot, no one was ever charged for the violence or property damage. On June 3, businessmen and civic leaders met to discuss raising funds and aid for rebuilding Greenwood, claiming that Tulsa had just suffered something worthy of shame and humiliation and restitution was their only way to recover. Despite this resolve, many black families were forced to live in tents during the winter of 1921-1922 as they worked to rebuild the district. On top of that, a group of influential white developers passed a fire ordinance that would prohibit full-sized wooden frame buildings to be constructed in the area, making it nearly impossible for most of the black families to rebuild. These developers wanted to redevelop the area for business and industry so that black people would be forced to move further from the center of the city.

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.
