The theory of evolution by natural selection, proposed by Charles Darwin, states that organisms with traits better suited to their environment are more likely to survive and reproduce. Over time, these advantageous traits become more common in the population. Natural selection drives the adaptation of species to their environment through the differential survival and reproduction of individuals.

Instruction: Brief me on the history of the Met Gala according to the info below: 

History
The Met Gala was established in 1948 by fashion publicist Eleanor Lambert as a fundraiser for the newly founded Costume Institute to mark the opening of its annual exhibit. The first gala comprised a dinner, and tickets were 50 dollars each.[7] Over the first few decades of its existence, the Gala was simply one of many annual benefits held for New York charitable institutions. Accordingly, the attendees of the early galas were almost entirely members of New York high society or the city's fashion industry. From 1948 to 1971, the event was held at various Manhattan venues, including the Waldorf Astoria, Central Park, and the Rainbow Room.[8]

When Diana Vreeland became consultant to the Costume Institute in 1972, the Gala began to evolve into a more global and glamorous affair, although one that was still aimed at the high-societal set.[9] The event started to become higher profile celebrity-oriented with attendees like Elizabeth Taylor, Andy Warhol, Bianca Jagger, Diana Ross, Elton John, Liza Minnelli, Madonna, and Cher intermixing with the city's elite.[8] It was during the Vreeland years that the Gala was first held at the Met and that Gala themes were introduced.[8]

The Met Gala is widely regarded as among the most prominent and most exclusive social events in the world. It is also one of the biggest fundraising nights in New York City, with US$9 million raised in 2013, $12 million the following year, and then rising to a record $17.4 million by 2022.[10][11][12][13] The Met Gala is one of the most notable sources of funding for the Institute,[14] with total contributions surpassing $200 million for the first time after the 2019 event. Anna Wintour, the chairperson of the event, assumed the chairmanship of the Institute in 1995. Also, The Met Gala is held on the first Monday in May, according to Wintour. Her guest list grew to include celebrities globally from the worlds of fashion, entertainment, business, sports, and politics who would eventually grace the pages of Vogue.[4]

Since 1948, the Met Gala has occurred consecutively each year, except in 2000 and 2002.[citation needed] The 2020 Met Gala was canceled due to the COVID-19 pandemic.[15] The Gala resumed in 2021, but was held in September rather than in May that year.[16] In 2022, the Gala returned to holding its traditional May ceremony.[17]

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.
