Question

question 31
one reason why live radio performances were so popular is
○ the invention of the microphone allowed singers to be heard over the band live.
○ because swing jazz music was so popular.
○ radio stations needed a way to fill in programming.
○ performances sounded better than recordings.
○ that was the only way music could be broadcast.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: The invention of the microphone allowed singers to be heard over the band live. This is a valid technological reason that made live radio performances feasible and appealing, as microphones solved the problem of singers being drowned out by bands during live broadcasts.
• Option 2: Swing jazz popularity is a genre trend, not a core reason for live radio performance popularity (other genres were also broadcast live).
• Option 3: Radio stations filling programming is about station needs, not why live performances were popular with audiences.
• Option 4: Saying live performances "sounded better" is subjective and not a widely accepted historical reason.
• Option 5: "Only way" is incorrect, as recordings could be (and were) broadcast too.

Answer:

the invention of the microphone allowed singers to be heard over the band live.
