Question:
Frederik Willem de Klerk DMS (Afrikaans pronunciation: ['frI@d@r@k 'v@l@m d@ 'klerk]; born 18 March 1936) is a South African politician who served as State President of South Africa from 1989 to 1994 and as Deputy President from 1994 to 1996. South Africa's last head of state from the era of white-minority rule, his government focused on dismantling the apartheid system and introducing universal suffrage.
De Klerk had been unhappy that changes had been made to the inauguration ceremony, rendering it multi-religious rather than reflecting the newly elected leader's particular denomination. When he was being sworn in, and the chief justice said "So help me God", de Klerk did not repeat this, instead stating, in Afrikaans: "So help me the triune God, Father, Son, and Holy Spirit".  Mandela reappointed de Klerk's finance minister, Derek Keys, and retained Chris Stals, a former member of the Broederbond, as the head of the Central Bank. De Klerk supported the coalition's economic policies, stating that it "accepted a broad framework of responsible economic policies".  De Klerk's working relationship with Mandela was often strained, with the former finding it difficult adjusting to the fact that he was no longer president. De Klerk also felt that Mandela deliberately humiliated him, while Mandela found de Klerk to be needlessly provocative in cabinet. One dispute occurred in September 1995, after Mandela gave a Johannesburg speech criticising the National Party. Angered, de Klerk avoided Mandela until the latter requested they meet; when they ran into each other, they publicly argued in the street. Mandela later expressed regret for their disagreement but did not apologise for his original comments. De Klerk was also having problems from within his own party, some of whose members claimed that he was neglecting the party while in the government.  Many in the National Party--including many members of its executive committee--were unhappy with the other parties agreed upon a new constitution in May 1996. The party had wanted the constitution to guarantee that it would be represented in the government until 2004, although it did not do this. On 9 May, de Klerk announced that the National Party would withdraw from the coalition government. The decision shocked several of his six fellow Afrikaner cabinet colleagues; Pik Botha, for example, was left without a job as a result. Roelf Meyer reported feeling betrayed by de Klerk's act, while Leon Wessels thought that de Klerk had not tried hard enough to make the coalition work. De Klerk announced that he would lead the National Party in vigorous opposition to Mandela's government, stating that he wanted to ensure "a proper multi-party democracy, without which there may be a danger of South Africa lapsing into the African pattern of one-party states".

Question:
Michael Bloomberg was born at St. Elizabeth's Hospital, in the Brighton neighborhood of Boston, on February 14, 1942. Bloomberg's family is Jewish. Bloomberg's father, William Henry Bloomberg (1906-1963), was born in Chelsea, Massachusetts and worked as an accountant for a dairy company. He was the son of Alexander "Elick" Bloomberg, an immigrant from Russia.
During his second term as the mayor of New York City, Bloomberg unveiled PlaNYC: A Greener, Greater New York on April 22, 2007, to fight global warming, protect the environment and prepare for the projected 1 million additional people expected to be living in the city by the year 2030.  Under PlaNYC, in just 6 years New York City reduced citywide greenhouse gas emissions by 19% since 2005 and was on track to achieve a 30% reduction ahead of the PlaNYC 2030 goal. In October 2007 as part of PlaNYC, Bloomberg launched the Million Trees NYC initiative, which aimed to plant and care for one million trees throughout the city in the next decade. In November 2015, New York City planted its one millionth tree, two years ahead of the original 10-year schedule.  In 2008, Bloomberg convened the New York City Panel on Climate Change (NPCC), an effort to prepare the city for climate change. In 2012, Travel + Leisure readers voted New York City the "Dirtiest American City," for having the most extant litter. Bloomberg has been involved in motivating other cities to make changes and has spoken about reducing carbon dioxide emissions, using cleaner and more efficient fuels, using congestion pricing in New York City, and encouraging public transportation.  Bloomberg unveiled the Special Initiative for Rebuilding and Resiliency (SIRR) in June 2013, after the city was affected by Hurricane Sandy in October 2012. The $20-billion initiative laid out extensive plans to protect New York City against future the impacts of climate change. On September 26, 2013, Bloomberg announced that his administration's air pollution reduction efforts had resulted in the best air quality in New York City in more than 50 years. The majority of the air quality improvement was attributed to the phasing out of heavy polluting heating oils through New York's "Clean Heat" program. As a result of the improved air quality, the average life expectancy of New Yorkers had increased three years during Bloomberg's tenure, compared to 1.8 years in the rest of the country.
