Recent statistic make it seem unlikely that the total consumtion of electricity determines its cost to individual consumers. Recent increase in total consumtion especially during summer months have sometimes been accompanied by a decrease in the cost per unit and at other times by an increase.

Which of the following position is best supported by the information presented above?

A. It must be the case that the cost of electicity to comsumer is what determines the total consumption.

B. Even though a correlation exists between the total consumption of electricity and its cost to consumer, no casual relation exists.

C. Further investigation into the way these statistics were gathered is certainly called for.

D. The cost of electicity depends upon something other than the total consumption of electricity.

E. The cost per unit of electricity to consumer is dependant on the total electicity consumption.

I didnt get what the argument is conveying, someone please expalin

It should be "D. It is cause and effect reasoning. If "X" does not lead to "Y" and "Y " does not lead to "X", there has to be a cause "Z" which leads to "X" or "Y"

This is a "must be true" question. Always keep in mind "no new information accepted", the right answer must pass the "Fact test".

ANALYZE THE STIMULUS:

Fact: Recent statistic shows that total consumption of electricity could not determine its cost to individual consumers.
Fact: Recent increase in total consumption especially ==> accompanied by a decrease in the cost per unit and by an increase at other times

What must be true based on the information above.

A. It must be the case that the cost of electicity to comsumer is what determines the total consumption.

B.Even though a correlation exists between the total consumption of electricity and its cost to consumer, no casual relation exists.
Wrong. The stimulus says that total consumption of electricity is unlikely used to determine its cost to consumer. ==> cannot exist a correlation between A & B if A cannot be used to determine B.

C. Further investigation into the way these statistics were gathered is certainly called for.
Wrong. Out of scope. Nothing about "further investigation" ==> C does not pass the "Fact test"

D.The cost of electicity depends upon something other than the total consumption of electricity.
Correct. The stimulus says that total consumption of electricity is unlikely used to determine its cost to consumer. ==> there must be another factor used to determine the cost of electricity.

E.The cost per unit of electricity to consumer is dependant on the total electicity consumption.
Wrong. Nothing about "cost per unit". ==> E does not pass the "Fact test"

Hope it helps.

(A) It must be the cause - It is too strong for an answer

(B)Even though a correlation exists between the total consumption of electricity and its cost to consumer, no casual relation exists.

The question stem is just the opposite. BY saying that , the increase in consumptions is accompanied by both increase and decrease in cost the author is actually ceasing
any possibility of correlation. Hence it can be removed

(C) is out of scope

(D) This is the answer. When the author clearly destroys any ground of correlation between the cost and consumption , there can be only possibility left. May be some other factors such as, a government tax increase or crude oil price increase are responsible for the price fluctuation

(E) is out of scope

Why not C?
"Recent statistics make it seem unlikely" so we need more information on this.

D is close but "something other", it can be what author is saying as well..."seem unlikely that" is used, not 100% sure.

The question asks " position is best supported by the information presented above "...

Thus the answer must flow directly from the stimulus presented to us.

(C) casts further doubt into the stimulus presented , which is no way called for !!

A. It must be the case that the cost of electicity to comsumer is what determines the total consumption. ( Wrong answer : Because the consumption is increasing in both the scenarios when cost has decreased as well as when cost has increased)
B.Even though a correlation exists between the total consumption of electricity and its cost to consumer, no casual relation exists. (Wrong answer : correlation itself is absent)
C. Further investigation into the way these statistics were gathered is certainly called for. ( wrong answer : Further investigation is out of scope)
D.The cost of electicity depends upon something other than the total consumption of electricity. ( Right answer : given the fact that decrease/increase in the cost of electricity is not accompained by increase/decrease in total consumption respectively. There must be an alternative caused involved that is affecting the total consumption of electricity apart from its cost.)
E.The cost per unit of electricity to consumer is dependant on the total electicity consumption( Wrong answer : this is not reflected in the argument.)

Which of the following position is best supported by the information presented above?

A. It must be the case that the cost of electicity to comsumer is what determines the total consumption.
_ Strong word 'must be' and also X causes Y 'unlikely' means it is false.
B.Even though a correlation exists between the total consumption of electricity and its cost to consumer, no casual relation exists.
'unlikely' - hence no co-relation.
C. Further investigation into the way these statistics were gathered is certainly called for.
Out of scope.
D.The cost of electicity depends upon something other than the total consumption of electricity.
There has to be one factor which causes this. X -> Y. Z causes X-> Y .
E.The cost per unit of electricity to consumer is dependant on the total electicity consumption.
Again no co-relation and no mention of dependence.

D: Cost of electricity sometimes increases, sometimes decreases
Hence, cost depends on something else than consumption
