There are really two questions here, that I can see. OneOne is "what were the specific requirements of the original Turing test, as stated by Turing himself.?" TheThe other is "what"What should the specific requirements of a modern Turing test be?" ThingsThings have advanced a lot since Turing's day, and I think it's reasonable for us to consider extending / modifyingmodifying his test to reflect our current understanding.
The answer to the first question is easy enough to look up, so I think the interesting one is the second one. WhatWhat should a test to determine intelligence look like? With that in mind, I think the answer to all four questions posed by the OP is "it depends". II don't think there's universal consensus on how to structure a perfect Turing test, so a given experimenter is really free to set things up however he/she wants.
This is all, of course, based on the assumption that the Turing test, or a Turing-test Test-like test is actually of value. That'sThat's not necessarily a given. Consider that, to some extent, what we're talking about is designing an AI with an exceptional ability for deceit! ThatThat is, assuming the questioner is allowed to simply ask "are you human", then we have to assume that the AI is supposed to lie if it wants to pass the test. SoSo one might rightly ask, is designing a system to be really good at telling lies, a valuable approach to AI?
