The correct answer choice is (D)
This question tests the limited scenarios that result when Z is added first. When Z is added first, M cannot be second, third, or last. Hence, we can create two hypotheticals based on the position of M:
Because the position of M is restricted, we should first apply the last rule (and the third rule because it affects K and T) :
Finally, by applying the second rule, we can fill in each hypothetical:
When applying the second rule, in Hypothetical #1 we can infer that O must be added fifth by taking the following steps:
- 1. There are only three open spaces.
2. Since K/T M, we know that K/T must be added second or third.
3. Since L O, L must then be second or third.
4. The only remaining space for O is the fifth.
Both hypotheticals must be considered when answering the question. Answer choice (D) is correct because in Hypothetical #1 we know M is fourth, and in Hypothetical #2 we know L cannot be fourth because L O. Thus, L cannot be added fourth when Z is added first.
Question #5 is probably the most difficult question, and the only effective way to attack the question is to use hypotheticals. Hopefully, by quickly answering questions #1 through #4 you will build enough time to comfortably work through question #5.
