Could you share rationale for 401538 @Brian_BH ?
Have some of my rationales not been showing up on your end? I swear I type them all in.
In any case, I got you 
:
QID 401538:
This rationale would be the same as the above: the question presumes knowledge of, in this case, the digestive system effect of increased parasympathetic nervous system activation. Knowledge that this would increase digestive system activity is a necessary discriminator to be able to answer the question appropriately.
Thanks @Brian_BH !
