reasoning error [#permalink] New post 07 Jul 2005, 05:53
Dobson: Some historians claim that the people who built a ring of stones thousands of years ago in Britain were knowledgeable about celestial events. The ground for this claim is that two of the stones determine a line pointing directly to the position of the sun at sunrise at the spring equinox. There are many stones in the ring, however, so the chance that one pair will point in a celestially significant direction is large. Therefore, the people who built the ring were not knowledgeable about celestial events.

Which one of the following is an error of reasoning in Dobson’s argument?

(A) The failure of cited evidence to establish a statement is taken as evidence that that statement is false.

(B) Dobson’s conclusion logically contradicts some of the evidence presented in support of it.

(C) Statements that absolutely establish Dobson’s conclusion are treated as if they merely give some support to that conclusion.

(D) Something that is merely a matter of opinion is treated as if it were subject to verification as a matter of fact.

(E) Dobson’s drawing the conclusion relies on interpreting a key term in two different ways.

A)...if cited evidence is right (stones...) then they were knowledgeable <> if cited evidence is NOT right then they are NOT knowledgeable. the cited evidence can be wrong but the ppl can still be knowledgeable.

Picked A.

Pretty much clear, just because there is a probability of two stones in line without being thought of , it doesn't prove that they were not knowledgeable.
