Question 1 refers to Question 2, which refers to Question 4, so start with Question 4 and assume an answer (I started with A).
  • If 4A then 2C then 1B then 3B which violates 4A, so A is not the correct answer for Question 4.
  • If 4C then 2B then 1A then 3A, also
    if 4C then 8C then 5B then 7B then 6A which violates 8C.
  • If 4D then 2A then 1D then 3C. 6 requires at least one of the last four answers to be A, so 4D violated.
By elimination, the answer to 4 must be B.
If 4B then 2D then 1C then 3D.
  • At this point, the answer to Question 7 cannot be B (0) or D (3).
  • If 7A then both 5D and 6D, which violates 8.
The answer to Question 7 must be C.
  • If 5A then 6D then 8A which violates 8A!
  • If 5B then 6 is violated.
  • 5C already violated.
The answer to Question 5 must be D. If 5D then 6A then 8B.

The answer key to the multiple choice test must be:

1. C
2. D
3. D
4. B
5. D
6. A
7. C
8. B
