Question: How many seats are required for a majority in the parliament that the first informal Parliamentary group for HIV/AIDS was formed in? Passage 1:An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.
 Passage 2:The 2008 Olympics U.S. Men's Basketball Team represented the United States of America at the 2008 Summer Olympics in Beijing, China. They qualified for the Olympics by winning the FIBA American Championships 2007 held in Las Vegas, Nevada. The team was nicknamed the "Redeem Team", a play on an alternative name for the legendary 1992 squad that was called the "Dream Team", and a reference to the fact that the United States came away with disappointing Bronze Medals during the 2004 Summer Olympics and the 2006 FIBA World Championship. Kobe Bryant was named the team captain and Mike Krzyzewski was named the head coach of the 2008 team. LeBron James, called the "voice of the U.S. team" by Time, stated: "It's the gold, or it's failure." An ESPN program, Road to Redemption, followed the team's preparations.
 Passage 3:The project „Acceptance and Participation of People Living with HIV in Serbian Society” contributed to increasing the role of PLHIV, reinforcing their position in the society, organizing self-help groups and coordination of their activities, their integration in National association of PLHIV and promoting the fight against discrimination, all that for contributing to making sustainable mechanisms that would successfully protect human rights and allow them full access to public services and necessary therapy. PLHIV participation and lobbying for the overall improvement of their rights, establishment of National AIDS experts group which focuses on legislation concerning the matter and the establishment of the first informal Parliamentary group for HIV/AIDS in Serbian Parliament, helped PLHIV to speak freely and openly about their status, making their overall status and approach to prevention and therapy better. Further activities that have been planned include support to PLHIV Union and helping them to connect to relevant European networks, lobbying for permanent parliamentary group and continuing work of the Experts Group on urgent questions such are: the shortage of continuous control and therapy for PLHIV in prisons, the lack of CD4 and PCR tests or the change of legislation that criminalizes HIV transmission. This project was financed by the European Commission and implemented in cooperation with Hivos (Stichting Humanistisch Instituut voor Ontwikkelingssamenwerking – Humanist Institute for Co-operation with Developing Countries) from Netherlands during the period from 2008 until April 2011.
