question:
Question: Which country that Austria has a border barrier with has the highest population? Passage:Austrian border barriers are border barriers and migration management facilities constructed by Austria between November 2015 and January 2016 on its border with Slovenia and in 2016 on its border with Italy, as a response to European migrant crisis. They are located on internal European Union borders, since Austria, Italy, and Slovenia are members of the EU and the free travel Schengen Area with a common visa policy. The barrier on the Slovenian border is several kilometres long, located near the busiest border crossing, Spielfeld-Šentilj, and includes police facilities for screening and processing migrants. Another migration management facility with barriers located on Austria's Italian border near Brenner, South Tyrol was constructed in 2016.

question:
Question: Of the musical acts Vixen toured with, which one has been active the longest? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

question:
Question: On February 26, 2011, did Humphreys replace a player that was born in Ireland? Passage:At the end of the 2007–08 season, Humphreys was voted Player of the Year, Player of the 2000s and Hartlepool United's Player of the Century. He continued to be a key player in 2008–09, making a total of 54 appearances. He was a key figure once again in the 2009–10 season, missing just nine matches as a central midfielder. On 26 February 2011, Humphreys replaced Joe Gamble after 82 minutes to make his 473rd appearance for "Pools". This broke the record previously held by Watty Moore for over half a century. Over the course of the 2010–11 season he played 29 matches. On 2 August 2011, Humphreys was given a testimonial match against Premier League Sunderland to mark his ten years at Hartlepool United. Sunderland won 3–1, though the 5,757 fans present at the Victoria Park were reported to be very vocal in their appreciation of the veteran player. On 7 January 2012, Humphreys replaced Luke James 90 minutes into a 2–0 win over Rochdale to make his 500th appearance for "Pools". He signed an "undisclosed extension to his contract" in May 2012. He made 33 appearances in the 2012–13 campaign, as Hartlepool were relegated into League Two, though Humphreys was named on the League One team of the week after scoring in a 3–2 win at Sheffield United on 29 December.
