Air rushes toward the equator from the north and south ______ .
选项 A、because of the dry air
B、because of the cool air

答案C
解析 根据题干信息词air rushes和the equator定位到第二个小标题下的第七段首句Because of the lower air pressure，air rushes toward the equator from the north and south。根据文章表述，由于气压较低，空气从南北部通向赤道，在变暖的过程中上升，把干燥的空气推向南部和北部，故本题选C。
