I believe the statment 1 Q2 and statement 3 Q3 are really challenging and definitely 705+/755+ level, and they are just beautifully articulated. These two parts of the questions test all the 3 tabs data simultaneously. I completely missed them because I didn't pay much attention to Tab 2. That one tab totally shifts the narrative completely for Sarah. Because Sarah was already on the stimulants (as per Tab 2), her results were already compromised (Tab 3 last sentence). Statement 1 in Q2 states that noise disturbance has caused her results to mislead. However, she was already compromised. Nothing additional factor would make her results magically change. They would still make it to be misleading, if not they'd do it more because of the added noise distrubance. It acts like a strengthener that her results are still compromised and won't alter the initial results.
Hence, it's No.
For Statment 3 Q3, because she had already taken the stimulants, her results were already misleading. Typically, if the Tab 2's data is omitted and this constraint was not considered, then the MSLT results from Tab 3 and the statements in Tab 1 completely destroys what the Statement 3 states about her. And the answer would have been False. Her average MSLT/mean MSLT is greater than 2. Tab 1 states that if it's less then 2 then the patient is not exaggerating and they are definitely suffering from fatigue rather than sleepiness, meaning the patient is actually suffering form fatigue rather than sleepiness. Because her means MSLT is not less than or equal to 2, we can say that she is definitely not suffering from fatigue rather than sleepiness. We can 100% with certainity say that she didn't suffer from fatigue rather than sleepliness.
Once we combine the constraint from Tab 2, the entire narrative shifts. As it states that because she is under stimulants and stimulants actually mislead the MSLT results, now there is a possiblilty that our initial result where we were certain that she is not suffering from fatigue rather than sleepliness is in doubt. There is definitely a possibility that she is suffering from fatigue rather than sleepiness.
Hence, True. The entire architecture of these two questions is just beautiful. There are several hidden constraints that could be easily missed out.
