B、The duration of an ice-age cycle.
C、Whether the ice-age cycle is related to the changes in Earth’s orbit.
D、How fast the seas rose when the ice-age cycle was about to start.
答案
A
解析
第4段提到的“puzzle”是针对第3段讨论的话题的,第3段讨论的主题是“冰河时代周期循环的原因”,而该段最后一句提到至今为止,没有人能找到其确切的原因,所以在第4段称之为“puzzle”,由此可见,puzzle指的是“冰河时代周期循环的原因”。因此,本题应选A。
