2. Twenty-four solar terms originated in the Yellow River Basin, and also reflected the typical northern climate characteristics?
You can do this problem by elimination.
Leave option a first, which does not involve the given material.
Option b, the length of noon shadow measured by Tugui can only determine 4 solar terms, but not 24 solar terms. Can be ruled out.
C option, the shadow under the soil can not be determined, only the length of the shadow at noon can determine the solar terms. Can be ruled out.
Option D, only recorded in Shangshu, but completely recorded in Huainanzi. Can be ruled out.
So there is only a left in the end, so choose a.
