With a diameter of approximately 114,000 kilometers at the equator, Saturn’s rotational speed spins it completely around in a little more than ten hours. Either Saturn is composed entirely of gas, or it has a small dense center surrounded by a layer of liquid and a deep atmosphere. Saturn’s atmosphere is much like that of Jupiter, except that the temperature at the top of its cloud layer is at least 38 degrees C. lower. [br] The word that in the passage refers to
选项 A、gas
B、center
C、atmosphere
D、temperature
答案 C
解析 The subject of the sentence is atmosphere. Logic tells you that that refers to atmosphere.
