請教大位先生一題OG12之第六題

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.


6. According to the passage, the researchers believe that
the high frequency of tooth breakage in carnivores
found at La Brea was caused primarily by
(A) the aging process in individual carnivores
(B) contact between the fossils in the pits
(C) poor preservation of the fossils after they were
removed from the pits
(D) the impact of carnivores’ teeth against the
bones of their prey
(E) the impact of carnivores’ teeth against the
bones of other carnivores during fights over kills
不懂為什麼選D
我選的是E8. According to the passage, if the researchers had NOT
found that two extinct carnivore species were free of
tooth breakage, the researchers would have
concluded that
(A) the difference in breakage frequencies could
have been the result of damage to the fossil
remains in the La Brea pits
(B) the fossils in other Pleistocene sites could have
higher breakage frequencies than do the fossils
in the La Brea pits
(C) Pleistocene carnivore species probably behaved
very similarly to one another with respect to
consumption of carcasses
(D) all Pleistocene carnivore species differed
behaviorally from present-day carnivore species
(E) predator densities during the Pleistocene era
were extremely high

不知道在講哪段
遇到這種題目要怎麼回去定位??

請幫幫忙解惑
