Question ID:PT8 S1 Q18 Passage:Jones: Prehistoric wooden tools found in South America have been dated to 13,000 years ago. Although scientists attribute these tools to peoples whose ancestors first crossed into the Americas from Siberia to Alaska, this cannot be correct. In order to have reached a site so far south, these peoples must have been migrating southward well before 13,000 years ago. However, no such tools dating to before 13,000 years ago have been found anywhere between Alaska and South America. Smith: Your evidence is inconclusive. Those tools were found in peat bogs, which are rare in the Americas. Wooden tools in soils other than peat bogs usually decompose within only a few years. Stem:Smith responds to Jones by Correct Answer Choice:EChoice A:citing several studies that invalidate Jones’s conclusion Choice B:accusing Jones of distorting the scientists’ position Choice C:disputing the accuracy of the supporting evidence cited by Jones Choice D:showing that Jones’s evidence actually supports the denial of Jones’s conclusion Choice E:challenging an implicit assumption in Jones’s argument
