To find the song number that was sung on the 73rd turn, you need to determine the pattern of how the songs are assigned to the singers.

In this Sing Thing scenario, the first 4 singers sang Song 1, the next 4 singers sang Song 2, and so on. This pattern suggests that each song is repeated every 4 turns.

To find the song number for the 73rd turn, divide 73 by 4 and find the remainder. This will give you the position of the singer within the current cycle.

Dividing 73 by 4 gives you a quotient of 18 and a remainder of 1. This means that the 73rd turn is the first turn in the 19th cycle. Since each song is repeated every 4 turns, the song number for the 73rd turn must also be the song number for the 1st turn in the 19th cycle, which is Song 1.

Therefore, the correct answer is B. 19
