정답 해설

[PASSAGE] "Now, a common misconception is that Bebop simply evolved from Swing, a natural next step. But that's a... well, it's an oversimplification. In many ways, Bebop was a conscious *rejection* of Swing." The professor uses this explicit comparison to show how Bebop differed from and deliberately pushed against Swing. [WHY CORRECT] Option 3 is correct because the professor organizes the lecture by first describing Swing and then directly contrasting its characteristics (mass entertainment, dancing, rigid arrangements) and motivations (commercial) with those of Bebop (art form, complex, individual expression, reclamation of identity). He uses phrases like "conscious rejection of Swing" and repeatedly compares and contrasts the two genres. [TRAPS] Option 1 is wrong because the professor does not present a chronological timeline of clubs; he focuses on the musical styles themselves. Option 2 is wrong because while Charlie Parker and Dizzy Gillespie are mentioned, the lecture does not compare their *musical theories*; it highlights them as examples of Bebop musicians. Option 4 is wrong because there's no mention of commercially successful songs. [TIP] To identify the main idea or organization, listen for explicit comparative language (e.g., "in contrast," "on the other hand," "unlike," "similar to") or clear shifts in focus from one topic to its counterpart.

오답이 틀린 이유

• Option A (“He presents a chronological timeline of famous jazz clubs in Harlem.”) confuses two separate points from the text.
• Option B (“He compares the musical theories of Charlie Parker and Dizzy Gillespie.”) swaps the cause and effect described in the passage.
• Option D (“He lists the most commercially successful jazz songs of the 1940s.”) attaches the right fact to the wrong subject.
