Detailed Instructions: 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: Nordic folk music encompasses traditions from Denmark, Norway, Sweden, Finland, Iceland and the dependent countries Åland Islands, Faroe Islands, and Greenland, and nearby regions. Specific instruments vary between countries and regions, but some common instruments include the lur, säckpipa, Hardanger fiddle, keyed fiddle, willow flute, harp, mouth harp, and animal horns. Common genres in Nordic folk include ballads, herding music, and dance music, genres which trace back to the medieval era. Often, Nordic melodies will contain the phrase C2-B-G.In Swedish folk music, songs are monophonic, unemotional, and solemn in character, though working and festive songs might be more lively and rhythmic. Danish songs melodies tend to lean toward the major. In Icelandic folk music, the rímur, a form of epic poem dating back to the medieval era and Viking Age, is prominent. Faroese music contains dances directly descended from medieval ballad and epic poems, particularly from literature in the Icelandic tradition, and often follows unusual time signatures. Many Norwegian folk ballads follow a four-stanza structure known as stev. Stev alternate a trochaic tetrameter with a trimeter, and lines typically rhyme following an ABCB scheme, though stev are not standardized. Finnish folk music tends to be based on Karelian traditions and the meter and thematic material found in the Kalevala. These themes include magic, mysticism, shamanism, Viking sea voyages, Christian legends, and ballads and dance songs. The older runo song tradition follows meters such as 54, 58, or 24. Under Swedish and German influence, a newer, round-dance tradition based on the runo emerged – the rekilaulu – and these usually follow a 24 or 44 time. Sami music traditions (music from the Sami people throughout Fennoscandia) historically were rather insular, exerting little influence on the music surrounding cultures. Sami music is known for joiking, improvised singing particular to the performer. These songs are often sung accompanied by a drum.
