Which of the following most logically completes the argument?

Sviatovin is a medieval Moringian text whose author and exact date of composition are unknown. However the events in the life of Prince Sviatov that the text describes occurred in 1165, and in the diagram of Sviatov's family that accompanies the text his father,who died in 1167, is identified as still living. Thus Sviatovin must have been written between 1165 and 1167, assuming that            

(A)the life of Prince Sviatov is not the subject of any other medieval Moringian texts

(B)the author of Sviatovin intended it to provide as accurate a report about Prince Sviatov's exploits as possible

(C)the diagram accurately represents the composition of Sviatov's family at the time Sviatovin was written

(D)Sviatovrn is the earliest Moringian text whose composition can be dated to within a few years 

(E)Sviatovin was not written by Sviatov's father Himself

题目分析：原文探讨的主题很简单，就是这个作品的写作时间是否可以通过某些证据来证明。A说other test就不是这个作品了，跑题，干掉。B说信息的准确程度，还是跑题，杀。C说这些证据和写作时间的关系，就是原文探讨的主题，留着。D说这个作品是能确定写作日期的最早的作品，跑题，杀。E说这个作品不是S父亲本人写的，我谈的是写作日期，不是谁写的这个作品，杀。
