This happened many times in the past, it's not rediculous at all. Just think, if your sponsor pays a ton of money for your expedition, you'd better have something to show for it. Else no more money for next time/beheading, depending on what era you live in.


:lol: LMFAO, thanks for the laugh. Excellent way of thinking!

I will go with E as well. It is the only one that makes perfect sense...negate E and the whole argument falls apart. If the gold was added intentionally, then it was not the methods that were inaccurate.

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.
This is no way related to what assumption we need.
B. The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.
If they did not mine the same area, we can say that method used by Frobisher was correct. This goes opposite to our conclusion.
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.
Out of context, other 16th century scientist are not related here.
D. Frobisher did not have soil samples from any other Canadian island examined for gold content.
Argument already says samples were from a particular island we can not question that.
E. Gold was not added to the soil samples collected by Frobisher before the samples were examined.
perfect, if someone didn't add extra gold in sample and there was no actual gold on island....then Frobisher method was incorrect.

Can anyone help in explaining the answer with some good logic?


We have to give proof that method used by Frobisher was incorrect. In any assumption question that is the basic thing required "we never question assumption, we find information to make fool-proof our assumption". Now what can be underlined assumption to say method was incorrect.
Prethinking:
Samples analyzed by today's scientist and frobisher were exactly the same.

E is the correct answer

Conclusion - Thus the methods used to determine the gold content of Frobisher’s samples must have been inaccurate.
Premise - Neither expedition found any gold there. Modern analysis of the island’s soil indicates a very low gold content

The argument states that, because, no / inadequate gold sample was found during analysis, method used by frobisher was inaccurate.

Now, there could be multiple assumptions here. Like,

1) Modern analysis were flawed
2) Frobisher tested gold presence in a very very minute portion of land (say 0.01% of total area), whereas, modern analyst took the average of gold presence and said the presence to be inadequate based on overall area
3) Gold was intentionally added from outside in the oil sample by Frobisher in his sample

3) sound a good match with E

Undoubtfully E, as long as when negated it completely shutters the argument:
If we assume that sampled portion of soil was added gold then, Frobisher's method was accurate which contradicts with author's conclusion.

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.


This sentence has Causal pattern, and to strengthen the causal pattern we eliminate any alternate cause.In the given argument it is clearly provided tht the technique used by frobisher to find gold was flawed becuase the samples had gold but there was no actual gold on the island.With this we can say that ther was no other reason to find gold other than that the technique was flawed..

man, I missed the word "soil samples" from the island.
D cannot be the right answer because it does not give any extra information to evaluate the assumption.

Why is B incorrect?
I understood the following events - he gave soil samples which had high amounts of gold. Got funding, but they failed as the Island had no gold. But what if they mined a different part? I was stuck between E and B. E is possible, but so is B.
Please explain!

option E is the correct answer.

i found it silly initially, but after spending some more time, i realized that this is the correct answer.

all the other 4 options deviate from the main issue.

A) The gold content of the soil on Kodlunarn Island is much lower today than it was in the sixteenth century. ( if this is the reason, then we can't blame the method. negating this option does not affect the conclusion)

(B) The two mining expeditions funded by Elizabeth I did not mine the same part of Kodlunarn Island.( out of scope, we can't compare the two methods then if this is the case)

(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.( i found it little tempting, but it does not destroy the conclusion on negation)

(D) Frobisher did not have soil samples from any other Canadian island examined for gold content.( out of scope, we are talking about methods)

(E) Gold was not added to the soil samples collected by Frobisher before the samples were examined.(yes, correct option. if gold were added to the sample, then the result would have been positive n we can't say method was faulty. so it destroys the conclusion)
