question: musical note:sheet music:five-line staff
choices.label: A B C D
choices.text: stroke:characters:Chinese characters trees:forest:nature ear of rice:rice:fragrant rice satellite:nebula:universe
explanation: "sheet music" is a part of "musical note", and "musical note" includes "five-line staff", "characters" consist of "strokes", and "characters" include "chinese characters" "forest" consist of "trees", and "forest" is a part of "nature". the component of "ear of rice" includes "rice", but the word order is inconsistent with the query. natural celestial bodies that orbit a planet and periodically operate in a closed orbit are "satellites", including man-made satellites. "Nebulae" are interstellar clouds of dust, hydrogen, helium and other ionized gases. There is no obvious logical relationship between the two.
