The correct answer choice is (A)
The condition in this question stem creates an RM block. Initially, it may seem as though this block has a wide number of placement options, but take a moment to consider the five variable groups created by this rule:
The interaction of the RM block, the TS block, and the second rule limits the placement options of each variable (creating a classic Separation Principle scenario, a concept that will be discussed in more detail in the next chapter). For example, because the Fs cannot be consecutive, they must be separated by the two blocks. Consider this for a moment—if you have to separate the three Fs with just two blocks, where must the Fs be placed? One of the blocks has to separate the first two Fs, and the other block has to separate the last two Fs, like so:
If the two blocks are not placed as they are above, at least two of the Fs will be consecutive, violating the second rule. Consequently, the Fs are forced into the first, fourth, and seventh meetings. The two blocks are interchangeable, and either TS or RM could be in either position 2-3 or 5-6.
Answer choice (A): This is the correct answer choice. If you are still uncertain about this answer choice, try placing a variable other than F into the fourth meeting. You will quickly see that any variable other than F in the fourth meeting will not allow for a workable solution.
Answer choices (B), (C), (D), and (E): Each of these answer choices is incorrect because they would not yield a viable solution for the question.
