Ans:E
The restaurant business wastes more energy than any other industry in the United States. Nearly 80 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of inefficient equipment. At the same time, approximately 70 percent of restaurants in the United States are small businesses that are usually too cash poor to invest in energy-efficient technology.

Which of the following statements draws the most reliable conclusion from the information above

(A) The availability of energy-efficient equipment will reduce the energy costs of the restaurant industry by approximately 30 percent.
The question doesnt give any information on how much energy efficient equipment will reduce the energy costs by.

(B) No industry in the United States spends greater than $10 billion each year on energy.
Extreme answer/Out of scope

(C) By using energy-efficient technology, a small restaurant will reduce its expenses by a greater percentage than will a large restaurant.
The question does not compare expenses of a small and large restaurants.


(D) Approximately $2 billion of the amount spent on energy each year by the restaurant industry is not squandered.
Question says $8billion is squandered on energy costs. It does not specify if the remaining $2billion is a justified expense or is squandered on something else.

(E) The replacement of inefficient equipment represents the largest potential source of energy savings for the restaurant industry.
Correct answer.

E is the only one which must be true in all conditions.

D is incorrect, because what if 10 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of neon lights (just an example)? then the non-squandered amount reduces to $1b.

(D) Approximately $2 billion of the amount spent on energy each year by the restaurant industry is not squandered.----$ 2 B may be Squandered by something else.
(E) The replacement of inefficient equipment represents the largest potential source of energy savings for the restaurant industry. ---This seems to be a better conclusion. Less ambiguous than D

D and E were very confusing. But the necessity in D for the remaining amount not to be squandered away is extreme. It is not necessary to be so. E is decipherable from the premises and hence is the proper conclusion.

though E and D are close, but i think in the end it ill be E..as you cannot tell what constitutes rest of 20% so +1 for E

E

If you do POE
Then (A,B,C) goes off D also but had it said 2 billion on ‘electricity wastage’ then it would be right,
E is perfect as it state the obvious choice to save electricity wastage , concluding the statement.

E it is - if 80% of the energy spend of the restaurant industry is being squandered by inefficient equipment, it is clear that the replacement of inefficient equipment represents the largest potential resource of energy savings for the restaurant industry

"E" can be wrong.
It says that "The replacement of inefficient equipment represents the largest potential source of energy savings for the restaurant industry."

The arguement says that Nearly 80 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of inefficient equipment. Suppose this 80 % can be reduced to zero also by doing modifications in the inefficient equipments. In that case both Replacement and Modification represents the equally large potential source of energy savings for the restaurant industry. Replacement will not be the largest source then.

A- The availability of energy-efficient equipment will reduce the energy costs of the restaurant industry by approximately 30 percent. We cannot conclude that we will save 30% it can be more than 30% also

B- No industry in the United States spends greater than $10 billion each year on energy. --. the arguments talking abt restaurant industy and not abt all industry so this cannot be the conclusion.

C- By using energy-efficient technology, a small restaurant will reduce its expenses by a greater percentage than will a large restaurant. --> the argument is discussing energy wastage and not abt expenses.. So incorrect...

D- Approximately $2 billion of the amount spent on energy each year by the restaurant industry is not squandered. --> the argument states 80% is wasted by use of inefficient equipment and 20% can we wasted in other ways... so we cannot conclude that $2 billion is used efficiently...


E- The replacement of inefficient equipment represents the largest potential source of energy savings for the restaurant industry. --> from the argument we know 8 billion money spent is squandered by inefficient use of equipments. So by replcaing the equipments we can save enery.. therfore correct.

I think the answer is C. The answer E uses extreme language. D is not mentioned in the question stem.

its a good point raised by Jiten. But one should remember that he/she has to draw the most reliable conclusion of the above. All others apart from E are incorrect.

I like E for the conclusion question. But, what would be the answer if it had been an inference question? I still don't get how inference is different from conclusion. My understanding is that a conclusion would summarize what is being said in the stimulus and E does the job for a conclusion question. But, regarding inference, does one need to analyse the arguement? Help will be appreciated.

Dear Sharmila79,

Inference is anything that would logically follow given the argument and it is something that is not explicitly stated in the argument. A conclusion, on the other hand is something that logically follows from the premises. A conclusion is the whole point which the author of the argument wants to make.

Premise of the argument: "Nearly 80 percent of the $10 billion spent on energy by the restaurant industry each year is squandered by the use of inefficient equipment"

Conclusion of the argument is something which is drawn from the premises. Only Choice E can be concluded from the premise because any squandering of money that is more than 50% definitely represents the largest potential source of savings.

Choice D is wrong because , 80% of money that is squandered is based only on one factor i.e., use of inefficient equipment. There may be other factors which may also be squandering of money.

For (E) I doubt the phrase "largest potential source" . To me , "largest" is extreme .We have no idea whether there can be some other potential source, say a new innovation , which can do a better energy savings .

The source of this question is doubtful .
