Woven baskets characterized by a particular distinctive pattern have previously been found only in the immediate vicinity of the prehistoric village of Palea and therefore were believed to have been made only by the Palean people. Recently, however, archaeologists discovered such a "Palean" basket in Lithos, an ancient village across the Brim River from Palea. The Brim River is very deep and broad, and so the ancient Paleans could have crossed it only by boat, and no Palean boats have been found. Thus it follows that the so-called Palean baskets were not uniquely Palean.Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.
The woven baskets with specific patterns have been found only on the neighborhood of an ancient village of Palea, consequently it was believed that these baskets had been made only in this area. However, recently archaeologists discovered such a basket in Lithos, which was separated from Palea with the Brim River. The author of the argument is sure that Palean people had not passed the river, because it is broad and deep river and it could be passed only with boats, however no Palean boats were found in Lithos. Thus, based on this information the argument concludes that so-called Palean baskets were not intrinsic to Palean. Nevertheless, information provided in the argument is not sufficient to draw such a conclusion. Several evidences are needed, which absence considerably weakens the argument.
One reason why the author believes that Paleans had not passed the Brim River is that no Palean boats were found in Lithos area. Here we need evidence, whether there have been found Palean and Lithos boats in any place. This will help to reveal more about the issue. For example if there has not been found any Palen boat, maybe Paleans did not used to build boats at all. Moreover, if along with this there have been found Lithos boats, than it could happen that Lithos people had traveled to Palean and got baskets there. On the other hand, if no Lithos boats were found, instead Palean boats were found, than the claim of argument will get a bit stronger. Why not much stronger, because even in this case there is probability that Paleans had not leaft their boats in Lithos, that is why archaeologists have not found their remnants. On the other side, from the argument we see that baskets in Lithos have been found recently, so if now there is no boat found there, it does not mean it will not be after some time.
Why argument mentions boats is that the author believes that the only way to cross the Brim River could be boats because of its broadness and depth. However it is known fact that during long periods the relief and climate of the earth can change. For example there is no evidence that in prehistoric times the Brim River existed. It could have been formed later, because of changes in the earth surface. Moreover it could also happen than in those times the river was nor deep neither broad and people could pass it easily without boats or any other equipment. During centuries due to the change of climate this river could have become broader and deeper. Thus here the information about the geographic and climatic conditions of the area in ancient times is needed.
The argument draws conclusion based on poor and insufficient information. There are several evidences, which can have important impact in its validity. The presence of these evidences mentioned above can remarkably strengthen the argument, while their lack weakens it.
