question 10 of 25
a vinyl record has grooves carved into it that match the original sound waves. a cd uses digital versions of the original sound waves.
why might a cd be a more reliable way to copy and distribute a sound recording than a vinyl record?
a. a cd fails to accurately replicate the original sound waves.
b. a cd can easily lose information because of noise.
c. a cd uses a greater number of possible values to encode data.
d. a cd is easier to copy exactly over and over again.

Explanation:

Vinyl records have physical grooves which can degrade over time and be difficult to copy precisely. CDs use digital data which can be easily and accurately replicated multiple times without significant loss of quality. Options A and B are incorrect as CDs are designed to accurately replicate sound and are less prone to noise - related information loss compared to vinyl. Option C is not the main reason for CD's superiority in copying and distribution; the key is ease of exact copying.

Answer:

D. A CD is easier to copy exactly over and over again.
