AExcellent
BGood
CQuestionable
DPoor
Answer & Solution
Correct answer: B. Good
1. The table places pulse velocity of 4575 m/s and above as Excellent.
2. A pulse velocity between 3660 and 4575 m/s is rated Good.
3. 3050 to 3660 m/s falls under Questionable.
4. 2135 to 3050 m/s is Poor, and below 2135 m/s is Very Poor.
5. A reading of 3800 m/s sits within the Good band.
