Some geologists argue that if oil is as common in unsampled areas of the world as it is in those already sampled, our current estimate of reserves that exist underground must be multiplied by a factor of 10,000. From this we can conclude that we can meet the oil needs of the entire world for at least five centuries, even assuming that future consumption grows at an accelerating rate.

To reach the stated conclusion, the author must assume which of the following?

(A) It is possible to recover the oil contained in unexplored areas of the world
(B) The consumption rate for oil will not grow rapidly
(C) Oil will remain an important energy source for at least 500 years
(D) The world will achieve and maintain zero population growth
(E) New technology will make oil discovery and drilling more feasible than ever before

To reach the stated conclusion, the author must assume which of the following?

A) It is possible to recover the oil contained in unexplored areas of the world
[Hold it]
B) The consumption rate for oil will not grow rapidly
[This is already taken into account . NEGATING it does not fail the conclusion]
C) Oil will remain an important energy source for at least 500 years
[Not possible, since if oil is not an energy source, conclusion is still valid]
D) The world will achieve and maintain zero population growth
[Out of scope- also even if future consumption grows its ok]
E) New technology will make oil discovery and drilling more feasible than ever before
[Out of scope]

Clear A.

I got this question from other forum and everybody is debating on OA....I also feel OA is wrong...can we discuss this question here?
Appreciate your help (managerial talks :-D )


They key word here is "From this" we can conclude that we can meet the oil needs of the entire world for at least five centuries.

So the answer is A

(A) It is possible to recover the oil contained in unexplored areas of the world
= >
oil is as common in unsampled areas of the world as it is in those already sampled

=> Oil needs to be recovered from these areas, hence A is correct

(B) The consumption rate for oil will not grow rapidly
=> It is stated in the prompt that consumption will increase rapidly but the oil can sustain this growth in consumption

(C) Oil will remain an important energy source for at least 500 years
= > Irrelevant, though I almost selected this answer

(D) The world will achieve and maintain zero population growth
=> Irrelevant Information

(E) New technology will make oil discovery and drilling more feasible than ever before
= > Irrelevant Information

I hope this helps :)

I also had to eliminat the others to come to A:

(A) It is possible to recover the oil contained in unexplored areas of the world
(B) The consumption rate for oil will not grow rapidly this has been stated
(C) Oil will remain an important energy source for at least 500 years this need not be true, it says at least 5 centuries

(D) The world will achieve and maintain zero population growth this is not needed as acceleration is mentioned already

(E) New technology will make oil discovery and drilling more feasible than ever before
we were never told drilling needs to be more feasible for achieving this

Some geologists argue that if oil is as common in unsampled areas of the world as it is in those already sampled, our current estimate of reserves that exist underground must be multiplied by a factor of 10,000. From this we can conclude that we can meet the oil needs of the entire world for at least five centuries, even assuming that future consumption grows at an accelerating rate.

Type - assumption

(A) It is possible to recover the oil contained in unexplored areas of the world - Correct - If we negate this , then the argument falls apart .
(B) The consumption rate for oil will not grow rapidly - Incorrect - the argument already mentions this explicitly
(C) Oil will remain an important energy source for at least 500 years - Irrelevant
(D) The world will achieve and maintain zero population growth - Irrelevant
(E) New technology will make oil discovery and drilling more feasible than ever before - Out of scope - the argument does claim of about such new tech

Answer A
