CDetermination of relative ages means that archaeologists can successfully compare rings of one log with rings of another log. The rings are characterized by thickness depended on the amount of rainfalls. Therefore, an answer have to explain how archaeologists could find rings of two distinct logs that corresponding to the same year.(A) The Pazyryk tombs were all robbed during ancient times, but breakage of the tombs seals allowed the seepage of water, which soon froze permanently, thereby preserving the tombs’ remaining artifacts. -

out(B) The Pazyryk Valley, surrounded by extremely high mountains, has a distinctive yearly pattern of rainfall, and so trees growing in the Pazyryk Valley have annual rings that are quite distinct from trees growing in nearby valleys. -

irrelevant comparison.(C) Each log in the Pazyryk tombs has among its rings a distinctive sequence of twelve annual rings representing six drought years followed by three rainy years and three more drought years. -

the best(D) The archaeologists determined that the youngest tree used in any of the tombs was 90 years old and that the oldest tree was 450 years old. -

it gives nothing.(E) All of the Pazyryk tombs contained cultural artifacts that can be dated to roughly 2300 years ago. -

archaeologists could determine relative ages, not absolute ages.
