In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[Q]: Passage: Opeth was formed as a death metal band in 1989 in Stockholm, Sweden, by lead vocalist David Isberg. Isberg asked former Eruption band member Mikael Åkerfeldt, who was just 16 years old at the time, to join Opeth as a bassist. When Åkerfeldt showed up to practice on the day after Isberg invited him, it became clear that Isberg had not told the band members, including the band's current bassist, that Åkerfeldt would be joining the band. An ensuing argument led to all members but Isberg and Åkerfeldt leaving to form a new project. The band name was derived from the word "Opet", taken from the Wilbur Smith novel The Sunbird. In this novel, Opet is the name of a fictional Phoenician city in South Africa translated as "City of the Moon".
Isberg and Åkerfeldt recruited drummer Anders Nordin, bassist Nick Döring, and guitarist Andreas Dimeo. Unsatisfied with Opeth's slow progress, Döring and Dimeo left the band after their first performance, and were replaced by guitarist Kim Pettersson and bassist Johan De Farfalla. After the next show, De Farfalla left Opeth to spend time with his girlfriend in Germany, and was initially replaced by Mattias Ander, before Åkerfeldt's friend Peter Lindgren took on the role of bassist. Rhythm guitarist Kim Pettersson left following the band's next performance, and Lindgren switched to guitar, with the role of bassist falling to Stefan Guteklint. The following year, David Isberg left the band citing "creative differences".Following Isberg's departure, Åkerfeldt took over vocal duties and he, Lindgren, and Nordin spent the next year writing and rehearsing new material. The group began to rely less on the blast beats and aggression typical of death metal, and incorporated acoustic guitars and guitar harmonies into their music; developing the core sound of Opeth. Bassist Guteklint was dismissed by the band after they signed their first record deal with Candlelight Records in 1994. Opeth initially employed former member De Farfalla as a session bassist for their demo recordings, and he went on to join on a full-time basis following the release of Opeth's debut album, "Orchid", in 1995.
[A]: What is the last name of the bassist who replaced the band member that was dismissed in 1994?
