Please elaborate how you arrive at the solution------

In Swartkans territory archaeologists discovered charred bone fragments dating back 1 million years. Analysis of fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfiresmade from branches of white stinkwood, the most common tree around swartkans.

Which of the foll, if true, would, together with the info above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?

a. The white stinkwood tree is used for building material by present-day inhabitants of swartkans
b. Forest fires can heat wood to a range of temeratures that occur in campfires
c. The bone fragments were fitted together by the archaeologists to form the complete skeleton of diff, animals
d. Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500,000 years ago
e. The bone fragments were found in several distict layers of limestone that contained primitive cutting tools known to have been used by early hominids

Reasons:

A : Irrelavant to the topic i.e. use of fire by homonids
B : This will actually waken the argument 'coz this could be a potential reason for finding of the bones
C : Though it speaks about the various animals that were formed from bones, it doesn't say if the homonids really burnt these animals for consuming or what so ever
D : Though this states that the early homonids used fire, it doesnot in any way support that the charred bones are evidnece of use of fire by early homonids. Also, there is a dispute of time. While this statement refers to a period about 500,000 years ago, the question talks about a period 1 million years ago
E : Answer : The bone fragments are found in the same strata as that of the tools used by the homonids, meaning, there is all possibility of them being used by the homonids. Since the question does not talk about the homonids, we need to find that answer which relates the homonids to the charred bones.

I guess the answer is going to be d as the most relevant (most logical).

E seems logical connecting tools found and the bones to hominids

gototknow3......Aren't we trying to make a connection between fire use and bone fragments?

Anyone can elucidate more on this type of a CR?

------------------------------------------------------------------------------------

Option D indicates the use of fire 500,000 years ago, but there is no connection between the charred bone fragments and the hominds.

Option E indicates cutting tools used by hominds for the bones and the question says bones found 1 million years ago.
Form which can be inferred that hominds used fire.

A) can be eliminated

B) this answer choice, if true, would weaken the claim that the charred bone fragments are an evidence of the use of fire by the early hominids. Because, it is giving an alternative explanation (charred bone fragments could have been the result of a forest fire rather than of the use of fire by early hominids).

C) we already know from the text that these charred bone fragments come from a variety of animals. can be eliminated.

D) this choice does not answer the question whether early hominids used fire 1 million years ago or not.

E) the only possible solution.
We already know from the text that these charred bones came from animals. we also know that they were heated to high temperatures and most probably branches of trees in question had been used.
We only have to find the agents of the action. And only E gives the best choice.

This is very interesting question, its asking to find a premise in the answer which together with the information in the question concludes that the charred bone fragments are evidence of the use of fire by early hominids?

A, B, C and D are outright not useful. Only E provides that premise. Although this look so easy, if you miss what question is asking you will end up spending to much time on it, like did. Please be in look out for these types of question that kill you time. Definitely a higher level question.

e. The bone fragments were found in several distict layers of limestone that contained primitive cutting tools known to have been used by early hominids

The question is an evaluate/strenghten question type: what specific info do we need to say that the bones are a sign of the presence of early hominids.

A- WRONG - The building habbits of present day inhabitants doesn't provide info about hominids 1 million years ago.
B- WRONG - This fact provide evidence against the proposition as it says that some natural disaster as forest fire could have provided the condition cited in the premise. This statement weakens the conclusion.
C- WRONG - This fact doesn't provide any useful information, a forest fire or early hominids killing or cooking entire animals would both leads to complete skeleton findings.
D- WRONG - Whether hominids used fire as many as 500 000 years ago is not relevant as we are interested about hominids 1 million years ago. Fire could have been discovered 750 000 years ago.
E- Correct Answer - This statement give further hints about the presence of early hominids as the cause of the bone findings, which is just enough to end up with the conclusion.

Hope it helps,
if yes Kudos are welcome.
