Question: How long had ŠK Slovan Bratislava been a team when Laskov won his third championship with them? Passage 1:Keity Souza Santos is an immunologist working at the allergy and immunology department of the University of São Paulo's school of medicine. Santos stated that she was the first person in her family to express interest in science as a career. She was inspired to become a biologist by the story of Dolly the sheep, the first mammal clone. She received her Bachelor's Degree in Biological Sciences from the University of São Paulo in 2003, and her doctorate in Allergy and Immunopathology in 2008 from the same institution. During her doctorate, she worked to find an anti-venom for the sting of Apis mellifera, which is also called the "Africanized honeybee." She did post-doctoral work in Salzburg, in Austria, and at Cornell University in Ithaca, in the USA. Her later work has been on identifying venom proteins in various insect stings, and in some cases, identifying the damage that they cause to tissues in the human body.
 Passage 2:Critical reaction to "The Gift That Keeps Giving" was generally positive with the New Musical Express rating it as one of the best on parent album Hey Venus!; "[it doesn't so much raise] the bar, as balances it on top of Mount Snowdon" going on to state: "From a foundation of ELO guitar cloud-swells, Gruff's Elvis Costello-in-a-bubblegum-bath voice wraps around tender trombone parps to create the band's most beautiful moment since "Demons". BBC Wales commented on the track's Christmas links, describing "The Gift That Keeps Giving" as a "mellow, mellifluous, slow ode to the joys of the festive season ... lyrically incredibly simple ... brain-bendingly catchy". The Guardian meanwhile, stated that the song "might sound more California than Christmas" but still possesses the "obligatory sleighbells ... shaken throughout". Much was made of the 'retro' nature of the track with Yahoo Music UK claiming that the song is "a pure blue-eyed soul tune, of the sort that Dan Penn and Spooner Oldham used to churn out four decades ago" and The Guardian describing it as a "gorgeous, Bacharach-tinged haze". In contrast the UCSD Guardian described "The Gift That Keeps Giving" as "jazzy" and "lo-fi" and saw it as "a throw-back to 2000's experimental Mwng".
 Passage 3:On 15 February 1946, Laskov immigrated to Brno, Czechoslovakia, where he studied medicine at the Masaryk University and played for SK Židenice, the modern 1. FC Brno. In 1947, he moved to Bratislava, where he married a Slovak beautician and was granted Czechoslovak citizenship. In Bratislava, he played for ŠK Slovan Bratislava between 1947 and 1952, winning the Czechoslovak First League in 1949, 1950 and 1951. In Czechoslovakia, he has also played for FK Inter Bratislava (then Cervena Hviezda) and TTS Trenčín players, until 1960. In the Czechoslovak Championship, he played a total of 169 games, of which 98 (with 48 league goals) for Slovan; he also featured in 3 games for the Czechoslovakia national football team. He was awarded several fair play prizes in Czechoslovakia. Later on, he worked as a manager, managing FK Inter Bratislava, FC Spartak Trnava and Trenčín. He also served as a professional physician specialized in otolaryngology and was an active member of the Bulgarian association in Slovakia.
