Input: Question: Did Kai have any siblings when he auditioned at the SM Youth Best Contest? Passage 1:Kohl is strongly pro-choice and opposes the death penalty. He is highly in favor of affirmative action and supports setting aside funds for women and minorities. Although he voted in favor of the 1996 Defense of Marriage Act, Kohl rejected the recent proposal to amend the U.S. Constitution to define marriage as between one man and one woman and has supported measures that ban discrimination based on sexual orientation. Kohl has consistently voted against the flag desecration amendment and in recent years has voted against restrictions on travel to Cuba and funding for TV Martí. In 2005, he secured a victory for one of his main causes: requiring handguns to be sold with child safety locks. The amendment was attached to the Protection of Lawful Commerce in Arms Act, with every Democrat and many Republicans voting in favor of the amendment. Earlier in his career, he helped push the Gun-Free Schools Act which the U.S. Supreme Court overturned in 1995 and has submitted many amendments to that effect. He is a strong supporter of public education and has rejected school vouchers. Kohl has voted in favor of allowing for the establishment of educational savings accounts.
 Passage 2:Exo-K's leader, Suho, was the first member to join SM Entertainment, after a successful audition through the company's casting system in 2006. The following year, Kai, with encouragement from his father, auditioned at the SM Youth Best Contest; he won and received a contract. Chanyeol, who took second place in a Smart Model Contest, and Sehun, who went through four auditions in two years, were the next members to become trainees in 2008. In 2010, Exo-K's D.O. sang for his audition and was eventually offered a contract. The last member of Exo-K to become a trainee was Baekhyun, who joined in 2011 through SM Entertainment's casting system and trained for approximately one year before debut. In Exo-M, Kris auditioned in 2008 at a global SM Entertainment audition in Canada, before moving to South Korea for training. That same year, Lay auditioned in Changsha, China, and subsequently moved to South Korea, while Xiumin attended an audition with his friend and won second place. In 2010, Luhan was scouted by an SM Entertainment representative in Seoul and passed his audition, while Tao was scouted at a talent show. The last member to join Exo-M was Chen, who took part in the casting system in 2011. The band's first televised performance was at the annual SBS Gayo Daejeon event on December 29, 2011.
 Passage 3:The consumption of yerba mate became widespread in the Spanish colony of Paraguay in the late 16th century both among Spanish settlers and indigenous Guaraní people, who had to some extent consumed it before the Spanish arrival. Mate consumption spread in the 17th century to the Platine region and from there to Chile and Peru. This widespread consumption turned it into Paraguay’s main commodity above other wares like tobacco, and Indian labour was used to harvest wild stands. In the mid 17th century Jesuits managed to domesticate the plant and establish plantations in their Indian reductions in Misiones, sparking severe competition with the Paraguayan harvesters of wild stands. After the expulsion of the Jesuits in the 1770s their plantations fell into decay as did their domestication secrets. The industry continued to be of prime importance for the Paraguayan economy after independence, but development in benefit of the Paraguayan state halted after the Paraguayan War (1864–1870) which devastated the country both economically and demographically. Brazil then became the prime producer of yerba mate. In Brazilian and Argentine projects in late 19th and early 20th century the plant was domesticated once again opening the way for modern plantation systems. When Brazilian entrepreneurs turned their attention to coffee in the 1930s Argentina, which had long been the prime consumer, took over as the largest producer, resurrecting Misiones Province where the Jesuits had once had most of their plantations. However, the coffee production regions in Brazil are distinct from the mate plantations. According to FAO in 2012, Brazil is the biggest producer of mate in the world with 513,256 MT (58%), followed by Argentina with 290,000 MT (32%) and Paraguay with 85,490 MT (10%).
