Reading the passage
The first paragraph explains the old approach: radiocarbon dating of material in shifted sediments. The rest introduces lichenometry and compares it with that approach. So the first method gives us the basis for the later comparison.
Working the answers
- A
We don't spend the rest of the account walking through radiocarbon dating step by step. We move to a different method.
- BCorrect
Radiocarbon dating is the established procedure; lichenometry is the new one. The final paragraph explicitly compares their accuracy and discusses conditions on using the new method.
- C
The author doesn't declare radiocarbon dating outdated and then rescue some usefulness for it. Introducing an alternative isn't the same as saying the established approach is obsolete.
- D
The second method is introduced as new, not as another traditional procedure.
- E
Limited accuracy doesn't mean the method has produced the particular erroneous conclusions this answer describes. No such history of mistaken conclusions is supplied.
