The current pattern of human consumption of resources, in [#permalink]  01 Nov 2005, 15:57
The current pattern of human consumption of resources, in which we rely on nonrenewable resources, for example metal ore, must eventually change. Since there is only so much metal ore available, ultimately we must either do without or turn to renewable resources to take its place.

Which one of the following is an assumption required by the argument?

(A) There are renewable resource replacements for all of the nonrenewable resources currently being consumed.
(B) We cannot indefinitely replace exhausted nonrenewable resources with other nonrenewable resources.
(C) A renewable resource cannot be exhausted by human consumption.
(D) Consumption of nonrenewable resources will not continue to increase in the future.
(E) Ultimately we cannot do without nonrenewable resources.

(B) We cannot indefinitely replace exhausted nonrenewable resources with other nonrenewable resources.
(C) A renewable resource cannot be exhausted by human consumption.
(D) Consumption of nonrenewable resources will not continue to increase in the near future.
(E) Ultimately we cannot do without nonrenewable resources.

Conclusion : We must either do without (start living without using) or turn to renewable.

Premise: Our reliance on nonrenewable source must change

We must provide an answer that must solve or justify either X or Y mentioned in the conclusion
"Do without part is clearly justified " as the the resources are less
Why should we turn to renewable must be answered by the help of the answer. As assumption is unstated part of premise and do a negation test
THough none of the options are 100% correct
best among the worst is c

C says: A renewable resource cannot be exhausted by human consumption.. this is true but is not true for OUR conclusion

B yes

Premise 1 - The current pattern of human consumption of resources, in which we rely on nonrenewable resources, for example metal ore, must eventually change
Premise 2 - there is only so much metal ore available
Conclusion - ultimately we must either do without or turn to renewable resources to take its place

Option B when negated destroys the premise on which the conclusion is based

Which one of the following is an assumption required by the argument?

(A) There are renewable resource replacements for all of the nonrenewable resources currently being consumed.the use of 'all' makes choice A extreme
(B) We cannot indefinitely replace exhausted nonrenewable resources with other nonrenewable resources. This is it
(C) A renewable resource cannot be exhausted by human consumption.irrelevant. How a renewable resource can be exhausted
(D) Consumption of nonrenewable resources will not continue to increase in the near future. rate of consumption is not part of the argument --> OOS
(E) Ultimately we cannot do without nonrenewable resources. this is a conclusion

Use the negation test to find the answer. If B is negated the argument collapses

Hello Mun23,

Let me try helping you with this one.

The passage concludes that the current pattern of human consumption of resource, which are nonrenewable, must eventually change. This is due to the limited availability of metal ore(non renewable resources). Soon we must either turn to renewable resource or do without these resources. This argument does not seem to have any hole at first sight so let us analyze the options.

(A) There are renewable resource replacements for all of the nonrenewable resources currently being consumed.
If there are renewable resource replacement for all non renewable resource, then the author would not have suggested that we might have to do without these resources. So, there is a possibility that some resources might not have renewable counterparts or replacements.
(B) We cannot indefinitely replace exhausted nonrenewable resources with other nonrenewable resources.
This is the assumption. If we could indefinitely replace nonrenewable resources with other nonrenewable resources, then we would not have to search for alternatives at all and could continue to live as we do now. Hence, this is the answer.
(C) A renewable resource cannot be exhausted by human consumption.
The author does not suggest this anywhere in the passage. That is why the author might have mentioned that we might have to do without the resource. We cannot be sure of whether the renewable resources can or cannot be exhausted based on that one statement.
(D) Consumption of nonrenewable resources will not continue to increase in the near future.
We do not care whether the consumption will increase or not. Even at the current rate of consumption, we might eventually complete the available resources. Hence, this statement is insufficient.
(E) Ultimately we cannot do without nonrenewable resources.
This is definitely not an assumption. The author himself suggests that we might have to make do with renewable resource or give up using such resources which suggests that we can do without nonrenewable resources.

Hope this helps! Let me know if I can help you any further.
