Question: Martina Hingis (born 30 September 1980) is a Swiss former professional tennis player who spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five Grand Slam singles titles, thirteen Grand Slam women's doubles titles, winning a calendar-year doubles Grand Slam in 1998, and seven Grand Slam mixed doubles titles; for a combined total of twenty-five major titles. In addition, she won the season-ending WTA Finals two times in singles and three times in doubles, and an Olympic silver medal.

In 2001, Switzerland, with Hingis and Roger Federer on its team, won the Hopman Cup. Hingis didn't drop a set in any of her singles matches during the event, defeating Tamarine Tanasugarn, Nicole Pratt, Amanda Coetzer, and Monica Seles. Federer was later quoted as saying: "I learned a lot from her, especially the two years I was here - once as a hitting partner and once as a partner with Martina. Definitely she helped me to become the player I am today." Hingis reached her fifth consecutive Australian Open final in 2001, defeating both of the Williams sisters en route, before losing to Jennifer Capriati. She briefly ended her coaching relationship with her mother Melanie early in the year but had a change of heart two months later just before the French Open. 2001 was her least successful year in several seasons, with only three tournament victories in total. She lost her No. 1 ranking for the last time (to Jennifer Capriati) on 14 October 2001. In that same month, Hingis underwent surgery on her right ankle. Coming back from injury, Hingis won the Australian Open doubles final at the start of 2002 (again teaming with Anna Kournikova) and reached a sixth straight Australian Open final in singles, again facing Capriati. Hingis led by a set and 4-0 and had four match points but lost in three sets. In May 2002, she needed another ankle ligament operation, this time on her left ankle. After that, she continued to struggle with injuries and was not able to recapture her best form. In February 2003, at the age of 22, Hingis announced her retirement from tennis, due to her injuries and being in pain. "I want to play tennis only for fun and concentrate more on horse riding and finish my studies." In several interviews, she has indicated she wishes to return to her home country and coach full-time. During this segment of her tennis career, Hingis won 40 singles titles and 36 doubles events. She held the World No. 1 singles ranking for a total of 209 weeks (fifth most following Steffi Graf, Martina Navratilova (after whom she was named), Chris Evert, and Serena Williams). In 2005, Tennis magazine put her in 22nd place in its list of 40 Greatest Players of the TENNIS era.

Question: Skinny Puppy is a Canadian industrial music group formed in Vancouver, British Columbia in 1982. The group is widely considered to be one of the founders of the electro-industrial genre. Initially envisioned as an experimental side project by cEvin Key (Kevin Crompton) while he was in the new wave band Images in Vogue, Skinny Puppy evolved into a full-time project with the addition of vocalist Nivek Ogre (Kevin Ogilvie). Over the course of a dozen studio albums and many live tours, Key and Ogre have been the only constant members.

Inspired by the music of Suicide, Cabaret Voltaire, Chrome, Throbbing Gristle, Nocturnal Emissions, Portion Control, and The Legendary Pink Dots, music which had been accessible to the band primarily via tape exchange, Skinny Puppy experimented with analog and digital recording techniques, composing multi-layered music with synthesizers, drum machines, acoustic percussion, tape-splices, found sounds, distortion, samplers, and conventional rock music instruments. They also incorporated samples from films and radio broadcasts into their songs, and applied liberal amounts of distortion and other effects to Ogre's vocals, which are often delivered in a stream of consciousness style. Lyrics commonly reference social and political topics including animal rights, environmental degradation, drug addiction, suicide, war, and the right to privacy. They have also highlighted events such as the Tiananmen Square protests of 1989 and the AIDS epidemic. These themes were often lyrically and conceptually intertwined. Skinny Puppy's often informal, improvisational approach to musical composition is indicated by use of the term brap, coined by them and defined as a verb meaning "to get together, hook up electronic instruments, get high, and record". Skinny Puppy's musical style has encompassed a wide selection of different genres, ranging from ambient music and synthpop, to noise rock and industrial metal.; the group is generally considered to be a pioneer of the electro-industrial genre. The Village Voice described Skinny Puppy's early work as "dark electro-pop", while Bill Coleman of Billboard magazine described Skinny Puppy as a "moody techno-outfit", going on to report their delivery as "aggravating". People magazine called Ogre's lyrical delivery as "incomprehensible", and likened the group's use of sampling to noises heard on "a TV set in an adjoining hotel room". AllMusic referred to Skinny Puppy's music as "primal" and " Kraftwerk gone netherworld", going on to state that unlike the bands that followed in their wake, "Ogre and Key knew how to craft tunes and marry them to the most ingenious of sound patterns". Some of Skinny Puppy's more recent offerings have been placed in genres such as glitch and intelligent dance music. Ogre said in an interview with the Auxiliary Magazine in June 2013, "there is a very military side to Industrial music, and we are far more in the psychedelic side."
