Four men and four women were nominated for two positions on the school board. One man and one woman were selected to the positions. Suppose the four men are named A,B,C, and D and the women are named E, F, G, and H. Further, suppose that the following statements are true: If either A or F won a position, then G won a position; If neither D nor G won a position, then B won a position; If either B won a position or H did not win a position, then C won a position; D cannot win a position unless E also won a position. Who were the two II ​ people selected to the school board and why?

Final answer:

By using logical deduction based on the given constraints, it is determined that person E and person C were selected for the school board positions.

Step-by-step explanation:

To solve this logic puzzle, we must analyze the given statements and use the process of elimination:

  1. If either A or F won a position, then G won a position.
  2. If neither D nor G won a position, then B won a position.
  3. If either B won a position or H did not win a position, then C won a position.
  4. D cannot win a position unless E also won a position.

Given that the school board must be composed of one man and one woman, let us consider that D cannot win unless E wins. Since only one woman can win, if E does not win, then D also does not win. Assuming D does not win, and following statement 2, B must win. If B wins, following statement 3, C also wins.

However, the board must consist of one man and one woman, and since B and C cannot both win as they are both men, our initial assumption that E does not win must be wrong. Therefore, E must win. If E wins, D is eligible to win but not certain to win.

Now let's consider the women. If E has won, A cannot win, or else G would also have to win, which isn't possible as only one woman can win. Hence, by statement 1, A and F cannot win. Since B also cannot win because E is already the winning woman, then by elimination, the winning man can only be C.

Thus, the two people selected to the school board are E and C.
