You cannot assume information that isn't stated in the question. With the given information, she/he/whoever draws the conclusion that the method was innaccurate.

There are many things that could have happened but only the things mentioned in the text are valid for the argument :)

The argument says that he got soil from Kodlunarn island examined. The Queen sent two expeditions there. The argument does not have anything to do with the other islands. It does not assume that he did not get soil of any other island examined. Perhaps he did and found no gold there or perhaps he did find gold there. We do not know and do not care as far as this argument goes. Here we are only concerned with Kodlunarn.

Frobisher, a sixteenth-century English explorer, had soil samples from Canada’s Kodlunarn Island examined for gold content. Because high gold content was reported, Elizabeth I funded two mining expeditions. Neither expedition found any gold there. Modern analysis of the island’s soil indicates a very low gold content. Thus the methods used to determine the gold content of Frobisher’s samples must have been inaccurate.

Which of the following is an assumption on which the argument depends?

(A) The gold content of the soil on Kodlunarn Island is much lower today than it was in the sixteenth century.
(B) The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.
(C) The methods used to assess gold content of the soil samples provided by
Frobisher were different from those generally used in the sixteenth century.
(D) Frobisher did not have soil samples from any other Canadian island examined for gold content.
(E) Gold was not added to the soil samples collected by Frobisher before the samples were examined.



Clearly E.

i am agree with C.
E doesn't make sense to me.
can any one tell me, where can i find the correct solution of this question apart from this discussion.?


321kumarsushant:
Option C says that when Frobisher examined the soil sample for gold he used a different method than anyone else was using back in the 1500s . Even if this is true, this statement does not affect the conclusion at all.
If choice C said "The methods used to assess gold content of the soil samples provided by Frobisher were different from those generally used in the twenty first century.", then it would be a contender for the correct answer.
Hope that helps.


E clearly. It's the only one that strays from the original line of the passage.

Susie,

That amendment to option C was a good addition.

Here the conclusion of the agument is that the methods used were wrong
A. since no timelines of Elizabeth's expeditions are given, and in fact it is implied that these were done after Frobisher's exploration - since they were done because of his report only- and since these also didnt find any gold, despite being done in 16th century, Statement A is wrong
B.Weak option - anyway which part of island does modern analysis base itself on - same or not? Since we dont know this, we cant say this is assumption on which the author's argument is based.
C. If methods were different, it doesnt mean they were wrong/ not wrong. incorrect
D. Othe islands are not being talked of here. Incorrect option
E. If frobisher added this gold himself, then both conditions are satisfied- the methods are correct and the soill doesnt have actually any gold. this argument is therefore based on this assumption.

IMO ans should be E

For C, we donot have sufficient information to assume whether the method used was different or not, but the use of "modern analysis" indicates that the present day test would be more accurate

Yes E its very simple.

We need to SUPPORT the assumption that METHOD USED TO TEST GOLD CONTENT was inaccurate.
E ) clearly states that Sample was not wrong and no gold was added to the sample .. so he had sample which had no gold yet his study showed gold was present
