To determine which example has four beats in each measure, we need to understand the specific rhythmic notation and the beats assigned to each segment. Let's break down each option to see if it satisfies the condition of having four beats per measure.
A. iddd Id dd d
Assuming 'i', 'd', and 'I' represent specific rhythmic values:
- 'i' might represent one beat.
- 'ddd' could represent three beats if each 'd' counts as one beat.
However, without a clear convention for the beats, it is hard to definitively assert that this option conforms to four beats per measure.
B. 9dd 凸ld 历d।
Similarly, the beats associated with '9', 'd', '凸', 'l', 'd', '历', 'd', and '。' need to be clearly defined.
With the notation given in each example, we cannot definitively establish how many beats per measure are represented without a clear understanding of the rhythmic value assigned to each character.
D. None of the above.
Given the ambiguity and lack of clarifying information on the rhythmic values in options A and B, the most reasonable conclusion is that none of the provided examples can be confidently asserted to have four beats in each measure.
Answer: D. None of the above.
