In Guatemala, archaeologists discovered that some fossils of ancient Elaphurus davidianus, an ancient deer in America, have some severe impairment on forehead of the deer. Clearly, therefore, since in the period when the ancient deer lived only the Maya used the trap that first struck the forehead of the prey, the fossils archaeologists discovered must be those of Maya’s prey.
Which of the following, if true, most weakens the argument above?
A. Some of ancient Elaphurus davidianus do have innate impairment on forehead.
B. The acid rain in Guatemala did not make additional damage on the fossils of ancient Elaphurus davidianus.
C. A great many Maya hunters, who frequently used the trap, lived in Guatemala.
D. Even if the ancient deer was struck by the trap, there would have been no treatment for it available in the period it lived.
E. The trap Maya used could not impair the preys to the extent comparable to that of archaeologist’s discovery
