【题目】咸蛋超人住在(20°W,23.5°S),有一天他想拜访住在地球另一端的面包超人,并决定“遁地”前去,于是他从家中钻入地底,始终保持直线前进并穿过地心到面包超人家。请你判断面包超人家的具体位置(  )
A.(20°W,23.5°S )
B.( 160°W,23.5°S )
C.(160°E,66.5°N )
D.( 160°E,23.5°N )

【答案】D
【解析】对趾点的特点:①关于地心对称;②两者位于不同的东西半球和南北半球上,时差为12小时;③两点纬度相同,但一个是北纬,一个是南纬;经度东西经相对且互补。因此咸蛋超人住在(23.5°S,20°W),在地球上通过地心另一侧的对趾点,面包超人的位置是(23.5°N,160°E)。
故选:D。
