I need help with ruling out "D". I chose "D" and I don't think I read Choice E; otherwise I ,ay have been tempted into "E".
For "D" my support for "informal observations of non trial uses" comes from Lines 46 when the author brings up an analogy to politicians where the strategy seems to work. The "CONTROLLED studies" refers to the court simulations; it is controlled meaning that it is a lab experiment and hence it is referring to a court simulation.
For "E", "research not directly related" referred to the psychology experiments (e.g. if you prime people ahead of time you have a "bad" past it could enhance your credibility/ethos) whereas the latter part of "E" directly and correctly points to the simulated trial situations. I accept that "E" is "correct" and understand how to get here but I am unsure with what I am missing with "D" to rule out "D".
