blinky got #5 correct.
ICOT got #’s 2 – 4 correct.
feivel got #1 correct.
squeak seems to have coincidentally gotten #1 correct with incorrect reasoning. Perhaps feivel can explain the logic.
That leaves #6 unresolved. ICOT, really there is no hints or Q&A allowed on these interview questions. But there isn’t only a single correct answer for that. Your “a)”‘s might be plausible, but isn’t the best response that was given for that question. (You’re playing with your life.) And there was no liquid mentioned, so assume none.
