A recent study has provided clues to
predator-prey dynamics in the late Pleistocene
era. Researchers compared the number of tooth
fractures in present-day carnivores with tooth
fractures in carnivores that lived 36,000 to 10,000
years ago and that were preserved in the Rancho
La Brea tar pits in Los Angeles. The breakage
frequencies in the extinct species were strikingly
higher than those in the present-day species.
In considering possible explanations for this
finding, the researchers dismissed demographic bias
because older individuals were not overrepresented
in the fossil samples. They rejected preservational
bias because a total absence of breakage in two
extinct species demonstrated that the fractures
were not the result of abrasion within the pits.
They ruled out local bias because breakage data
obtained from other Pleistocene sites were similar
to the La Brea data. The explanation they consider
most plausible is behavioral differences between
extinct and present-day carnivores—in particular,
more contact between the teeth of predators and
the bones of prey due to more thorough
consumption of carcasses by the extinct species.
Such thorough carcass consumption implies to
the researchers either that prey availability was
low, at least seasonally, or that there was intense
competition over kills and a high rate of carcass
theft due to relatively high predator densities.

4The primary purpose of the passage is to
(A) present several explanations for a well-known
fact

debate
(C) argue in favor of a controversial theory
(D) question the methodology used in a study
(E) discuss the implications of a research finding
答案E
想問C選項的意思是什麼 ? 看不懂

求问B为什么不对？E为什么会对，implication到底什么意思？

难道implication=explanation????

因为文章25行写了consumption implies to。。。

用排除法，就可以选E。

implication 也有 close concern的意思，可以理解为 含义

C：支持一个有争议的理论；文中显然没有这方面的意思。
B：对现有的争议问题给出新的解释；文中显然也没有提出大家对什么问题有不同的看法。
E：楼上的解释很明白。
