### HideShow timer Statistics

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.

The point at issue between Jones and Smith is

(A) whether all prehistoric tools that are 13,000 years or older were made of wood
(B) whether the scientistsâ€™ attribution of tools could be correct in light of Jonesâ€™s evidence
(C) whether the dating of the wooden tools by the scientists could be correct
(D) how long ago the peoples who crossed into the American from Siberia to Alaska first did so
(E) whether Smithâ€™s evidence entails that the wooden tools have been dated correctly

Here's my opinion on this:

A) whether all prehistoric tools that are 13,000 years or older were made of wood - nop. All tools is too strong.
(B) whether the scientistsâ€™ attribution of tools could be correct in light of Jonesâ€™s evidence - it's only one side of the debate. Nop.
(C) whether the dating of the wooden tools by the scientists could be correct - My pick of the 5. Jones is saying the scientists are wrong. Smith argues that the scientists could be right.
(D) how long ago the peoples who crossed into the American from Siberia to Alaska first did so - not relevant.
(E) whether Smithâ€™s evidence entails that the wooden tools have been dated correctly - same as B, only one side of the story.

The argument is about tools

So left with B and C

Smith is actually talking evidence provided by Jones

B it is
