Archaeologists in Michigan have excavated a Native American camp near Dumaw Creek. Radiocarbon dating of animal bones found at the site indicates that the camp dates from some time between 1605 and 1755. However, the camp probably dates to no later than 1630, since no European trade goods were found at the site, and European traders were active in the region from the 1620's onward.
Which of the following, if true, most strengthens the argument?
(A) Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.
(B) At all camps in the region that have been reliably dated to the late 1620's, remains of European trade goods have been found.
(C) The first European trade goods to reach the area would have been considered especially valuable and preserved as much as possible from loss or destruction.
(D) The first European traders in the area followed soon after the first European explorers.
(E) The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.
正解是B，我选的是C，因为我觉得B有盲目类比的嫌疑
B of course.
This is an argument evaluation problem.
Situation:Since no European trade goods were found at the site,the camp probably dates to no later than 1630.
Reasoning:What strengthen the argument?If all that camps later than 1630 were found with European trade goods,so the camp will be no later than 1630.
Choice B is right.C gives another phenomena but cannot strengthen the author's argument.
