The cafeteria of a certain elementary school provides a free lunch every day to the entire student body—a significant expense in the school's annual budget. A vice principal was exploring cost-reducing measures that would not compromise nourishment. A local Italian restaurant offered the school a large number of pizzas at a vastly reduced bulk rate. The pizzas were served one day, and afterward, the vice principal calculated that the cost of the pizza and delivery was slightly more than the average cost of typical cafeteria lunch day. Therefore, he concluded that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant.

Which of the following would be most useful for evaluating the conclusion drawn by the vice principal?

(A) How many pizzas were uneaten at the end of that day's lunch.

(B) Whether pizza provides the same level of nutrition as a typical cafeteria lunch.

(C) Whether another Italian restaurant in this town would provide a similar deal and offer free delivery.

(D) Whether other, more expensive dishes from that Italian restaurant, would provide a more balanced and varied set of nutrients.

(E) Whether the faculty preferred the pizza to the typical cafeteria lunch.

Hello anupamadw

The argument have a conclusion that pizzas were more expensife then lunch in cafeteria. But we have a gap in this story: How much pizzas were ordered? This was a first order so how do they know how much pizzas will be enough? Maybe they made a mistake and order too much pizzas? If this situation os true, then people just not eat a lot of pizzas and we potentially can save money by ordering much fewer pizzas.

The answer A asks about this moment.

Hi !
I am not convinced with the answer .. at first glance I did choose A .. but the conclusion of the Vice principal clearly states ..
Therefore, he concluded that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant....
Now I take option C ... it is posing a question that asks if there is any other restaurant that can offer a similar deal and free delivery ... If yes then conclusion validated ... if no then yes we cannot replace cafeteria lunch with pizzas...
and now i tilt to C....
Could you please correct me if I am wrong..
Also for A .. how many pizzas were left uneaten? many ... few... none ...?
many,none ... could be because of miscalculation of the requirement ...??
I feel we need to answer this...
could you help mikemcgarry...

this is an evaluate type of questions.
when answering the questions in the answer choices, we have to take 2 extremities. The correct answer choice, will be either a strengthener or a weakener of the argument, depending on the answer we give to it.

A. if there were no leftovers, then YES - pizza is not a good option. if there were a lot of uneaten pizzas, then the school ordered more than needed. thus, the costs CAN be reduced.
B - out of scope
C - irrelevant. delivery doesn't cost much (I don't think > 50$ at least..so no)
D - more expensive - not cost effective
E - preferences are out of scope.

This is my analysis.
Whenever there is an assumption question then try to accomplish one task. Try to weaken the argument.

The author concludes that no money can be saved by switching to pizza.
Lets consider the fact that we need to weaken this solution. Answer will tell us something that there is a way to decrease the cost.

A) How many pizzas were uneaten at the end of that day's lunch. hmmm we have an answer. if i know how many were not eaten and dumped in the bin then next time i will order less pizzas and will decrease my cost. I know decrease cost. I don't know. no decrease in cost
B) Whether pizza provides the same level of nutrition as a typical cafeteria lunch. This is not the topic of discussion. It is the expense.
C) Whether another Italian restaurant in this town would provide a similar deal and offer free delivery. We do not want to know this. The argument clearly says that it has to be "this " restaurant.
D) Whether other, more expensive dishes from that Italian restaurant, would provide a more balanced and varied set of nutrients. Again it is nutrients which is not what i want to know here. It is about expense from pizza
E) Whether the faculty preferred the pizza to the typical cafeteria lunch. Faculty preference i do not care. Only thing i care is expense from the pizza

The conclusion was about whether money was saved and not about whether food should be ordered from outside.

The best option to evaluate that will be to see how much they ordered.

Fell into B trap thinking it was related to nourishment. It is the cost that should be looked.

I don't agree with OA here.

A) How many pizzas were uneaten at the end of that day's lunch.
C) Whether another Italian restaurant in this town would provide a similar deal and offer free delivery.

First off, both these options are very open ended with their own assumption.
In real world, equal quantity is compared to consider which deal is good.

Lets say, there are 2 suppliers and provide A & B deal with same variant in tax, delivery terms etc. Now which deal is best, to know it, you have to consider same parameters.

he concluded that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant. => This is best on only 1 deal. so assumption here is

1 Local restaurant = All local restaurant price (Prethinking : 2)
Now assumption inbuilt here is "Delivery terms" makes a difference.

Assumption 2 is that quantity for both Lunches are same : Consider this you need a plate per student, while in Pizza lunch, 2 people can share a pizza. Has that been considered already by Principal.?

So IMO both A & C makes sense.

Here, the conclusion is "the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant."

Premise : The pizzas were served one day, and afterward, the vice principal calculated that the cost of the pizza and delivery was slightly more than the average cost of typical cafeteria lunch day.

Assumption: The quantity of pizza served and the quantity of free lunch on regular days is the same.

Notice the word in the conclusion "this restaurant.".

Principal said we cannot save money by buying pizza from this restaurant.. So, we need to maintain our scope till this restaurant only.

C is talking about other restaurant. It is irrelevant here as the claim is made for one restaurant only.

A is as per our pre thinking. If lets say none of the pizzas were left out, then the claim made by the principal is strengthened. BUT if pizzas were actually not eaten or were actually wasted and then the principal could ask the company to reduce the quantity before making such a claim. hence, a weaker.

Thus, A is the BEST answer.

Premise : lets reduce cost by offering pizza in place of a day's lunch. cost of pizza was a bit more.
Conclusion : the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant.
To achieve : answer following question in + and - and find if this exerciser will strengthening and weakening the argument.

A) How many pizzas were uneaten at the end of that day's lunch. --- let just say nothing left. this means that pizza was costly. while if 10 pizza left then next time order 10 less pizza and it might be able to save some bucks for us. correct answer.
B) Whether pizza provides the same level of nutrition as a typical cafeteria lunch. ---- We are trying to save some money.
C) Whether another Italian restaurant in this town would provide a similar deal and offer free delivery. ---- We are concerned with "this restaurant".
D) Whether other, more expensive dishes from that Italian restaurant, would provide a more balanced and varied set of nutrients. --- we need pizza only.
E) Whether the faculty preferred the pizza to the typical cafeteria lunch. --- who cares about the faculty.

The cafeteria of a certain elementary school provides a free lunch every day to the entire student body—a significant expense in the school's annual budget. A vice principal was exploring cost-reducing measures that would not compromise nourishment. A local Italian restaurant offered the school a large number of pizzas at a vastly reduced bulk rate. The pizzas were served one day, and afterward, the vice principal calculated that the cost of the pizza and delivery was slightly more than the average cost of typical cafeteria lunch day. Therefore, he concluded that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant.

Which of the following would be most useful for evaluating the conclusion drawn by the vice principal?

(A) How many pizzas were uneaten at the end of that day's lunch.

(B) Whether pizza provides the same level of nutrition as a typical cafeteria lunch.

(C) Whether another Italian restaurant in this town would provide a similar deal and offer free delivery.

(D) Whether other, more expensive dishes from that Italian restaurant, would provide a more balanced and varied set of nutrients.

(E) Whether the faculty preferred the pizza to the typical cafeteria lunch.

I chose the option B because it talks about the level of nutrition which is also a concern as mentioned in the second line. But remember we focus on the main conclusion of the argument which is “the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant.”

Nutrition is not in the scope of the argument. So, we can easily eliminate B and D.

It doesn’t matter what the faculty preferred as long as the cost was taken care of because that’s the main focus of the argument.

C is incorrect, as perfectly explained by abhimahna, because we are only talking about this restaurant. Any other restaurant will not be the focus of this argument.

A is our answer. If more pizzas were left that means the ordering of the pizzas was not done correctly and it might have caused the prices to go up and the school ended up spending more. It strengthens the conclusion that the school could not save money by replacing a day of cafeteria lunch with a day of pizza from this restaurant.
On the other hand if less pizzas or none of the pizzas were uneaten (all the pizzas were eaten) that means the school might have ordered the pizzas correctly which might have saved money. So this is a weakner.
