In the kidney transplant example, what is the limit for Level 2?

• A. 20
• B. 10
• C. 9999
• D. 1

Answer: (A)

This question hinges on how the levels are defined by a numeric cutoff in the kidney transplant example. Level 2 is set by an upper limit of twenty, meaning values at or below twenty fall into Level 2, while anything above would move to a higher level. That boundary makes twenty the appropriate limit for Level 2. The other numbers don’t fit the described cutoff: ten or one are outside or below the Level 2 ceiling according to the rule, and 9999 far exceeds it, proceeding to a different level. So the limit for Level 2 is twenty.
