Five racing drivers, Alan, Bob, Chris, Don, and Eugene, enter into a contest that consists of 6 races. The results of all six races are listed below:Bob always finishes ahead of Chris.Alan finishes either first or last.Eugene finishes either first or last.There are no ties in any raceEvery driver finishes each race.,In each race, two points are awarded for a fifth place finish, four points for fourth, six points for third, eight points for second, and ten points for first.If Eugene finishes two places ahead of Chris in the first race, all of the following will be true EXCEPTa) Bob finishes ahead of Don.b) Chris finishes two places ahead of Alan.c) Don finishes fourth.d) Bob finishes immediately behind Eugene.e) Chris finishes ahead of Bob."

Answer 1

e) Chris finishes ahead of Bob

The finishing order was:

Eugene

Bob

Chris

Don

Alan

The reasoning:

Eugene has to finish last or first, so to be ahead of Chris he has to be first. Chris is two places behind and therefore third. Bob has to finish ahead of Chris, and therefore must be second. Alan has to finish last or first, and first is already occupied, so he's last. That leaves fourth place for Don.
