Question: What was the age of Nusa Derenda the year that Slovenia achieved seventh place for only the second time in the Eurovision Song Contest? Passage:Prior to the 2020 Contest, Slovenia had participated in the Eurovision Song Contest twenty-five times since its first entry in . Slovenia's highest placing in the contest, to this point, has been seventh place, which the nation achieved on two occasions: in 1995 with the song "Prisluhni mi" performed by Darja Svajger and in 2001 with the song "Energy" performed by Nusa Derenda. The country's only other top ten result was achieved in 1997 when Tanja Ribic performing "Zbudi se" placed tenth. Since the introduction of semi-finals to the format of the contest in 2004, Slovenia had thus far only managed to qualify to the final on six occasions. In 2018, Slovenia was represented by Lea Sirk and the song "Hvala, ne!", which qualified to the final and placed twenty-second. One year later, in 2019, Slovenia qualified for the final again with Zala Kralj & Gasper Santl, finishing in fifteenth place with the song "Sebi".
