The last two lines suggest that wind and shade, which impact growth rates, must be factored in, which suggests that rather than eliminating conditions that impact growth rates, scientists must simply calculate their impact.

Why is D correct?

Happy to help. You asked why (D) is correct. Did you mean to ask why
(D) is incorrect? The correct answer is (B). I'll assume this is what
you meant; if it's not, feel free to reply with what you meant.

The question asks, "Which one of the following statements is most
strongly supported by the passage?"

(D) says, "Radiocarbon dating is more accurate than lichenometry in
dating earthquakes that occurred approximately 400 years ago."

The problem with this answer choice is that the last paragraph of the
passage tells us that the opposite is actually true and that
lichenometry has a functional limit of 500 years. The last paragraph
tells us that lichenometry has some distinct advantages over
radiocarbon dating. For one, radiocarbon dating is only accurate to
within plus or minus 40 years, whereas lichenometry is accurate to
within 10 years. Secondly, we're told that lichenometry is best used
for earthquakes within the last 500 years. This gives us enough
information to rule out (D).

(B) says, "Radiocarbon dating is unlikely to be helpful in dating past
earthquakes that have no identifiable fault lines associated with

(B) is supposed by line 3 of the text. In line 3, we're told that
radiocarbon dating involves using visible fault lines, so this answer
has direct support from the text. We can select (B).

Does this make sense? Let us know if you have any more questions!
