问题 How is the table salt we use obtained?
Which of the following is true?
选项 A、The ocean salinity is lower in tropical regions.
B、The ocean salinity is higher in coastal regions where rivers flow into the sea.
C、The ocean salinity is higher in dry regions.
D、The ocean salinity is lower in regions with little precipitation.
答案C
解析 排除题。根据课文内容，热带地区蒸发量大，所以含盐量也大，这排除了选项A。在有河流流入的海岸地区，海水被稀释，所以含盐量小，这排除了选项B。降雨少的地区，含盐量也大，这排除了选项D。选项C是正确答案。
