Answer:
Unclear exam questions could be construed as an example of violations of
Actuarial Standard of Practice #9 which requires that actuaries (FCAS
question writers) take preventative measures to prevent misuse (ambiguous
interpretation by exam candidates) of information and/or Actuarial Work
Products (the 1997 & 1998 CAS Exam 7) by ensuring clarity in actuarial
aspects. Furthermore, ASP #9 states that waiver of fees (by volunteer exam
question writers) does not eliminate the need to observe the professional
standards.
