 Submitted by Bryan Rating: 4.4091 (22 votes) Solution: (Hide) 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, alsoif 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. C2. D3. D4. B5. D6. A7. C8. B
