Section A: Quick Questions
Q1
A — Yes
Q2
B — No
Q3
A — No

Section B: Match the Pairs
Q1
Sampling → Measuring a sound wave many times per second
Q2
Bit depth → How much detail each sample captures
Q3
The original, real-world type of sound → Analogue sound
Q4
The result of sampling a sound wave → Digital audio
Q5
Analogue sound is already stored as binary → Wrong - analogue sound is a wave, not binary numbers
Q6
Sampling only happens once per song → Wrong - sampling happens thousands of times per second
Section C: Definitions

Q1
A — Sound is sampled to be stored as binary numbers.
Q2
B — Sampling happens thousands of times per second, not once.
Q3
C — Analogue sound is a wave, not binary numbers.
Q4
D — More samples usually give better quality, not less.
Q5
A — Bit depth does affect sound quality - more detail is captured.
