Final answer:
In duple-compound time, there are two beats per measure, and each beat is divided into three equal parts.
Step-by-step explanation:
The statement given in the question is true.
In duple-compound time, there are two beats per measure, and each beat is divided into three equal parts. This means that each measure consists of six equal parts, with each part having the same duration as the other two parts.
For example, if we assign each part a counting number, the beats in duple-compound time would be counted as 1-2-3-4-5-6, where each number represents an equal duration of time within the measure.
