答案：D

知识点：逻辑推理

难度评级：1060

解答：

Bret 在 $3$ 号座位。因为“Bret 挨着 Carl”是假的，Carl 不在 $2$ 号或 $4$ 号座位，所以 Carl 必须在 $1$ 号座位。

Bret（ $3$ 号）和 Carl（ $1$ 号）之间的座位是 $2$ 号。因为“Abby 在 Bret 和 Carl 之间”是假的，Abby 不在 $2$ 号，所以 Abby 必须在 $4$ 号。

因此 Dana 坐在 $2$ 号座位。

所以正确答案是 D。

Bret is in seat $3.$ Since "Bret is next to Carl" is false, Carl is not in seat $2$ or seat $4,$ so Carl must be in seat $1.$

The seat between Bret (seat $3$ ) and Carl (seat $1$ ) is seat $2.$ Since "Abby is between Bret and Carl" is false, Abby is not in seat $2,$ so Abby must be in seat $4.$

That leaves Dana in seat $2.$

Thus, the correct answer is D .
