Question #50. 341-02 (23608-!-item-!-188;#058&000341-02)

The passage suggests which of the following about the ring patterns of two trees that grew in the same area and that were of different, but overlapping, ages?

(A) The rings corresponding to the overlapping years would often exhibit similar patterns.
(B) The rings corresponding to the years in which only one of the trees was alive would not reliably indicate the climate conditions of those years.
(C) The rings corresponding to the overlapping years would exhibit similar patterns only if the trees were of the same species.
(D) The rings corresponding to the overlapping years could not be complacent rings.
(E) The rings corresponding to the overlapping years would provide a more reliable index of dry climate conditions than of wet conditions.

(D)這個答案要如何排除呀?
因為第一段末說 ring patterns of dead trees of different, but overlapping, ages 可以用來提供氣候狀況
第二段一開始又說 complacent rings 無法用來得知氣候的變遷
是不是就可以推得(D)的答案?
