Rather than bringing cash to school to pay for food expenses, Kindergrade School children will now use
electronic cards that record students’ purchases so that parents can later be billed. The objective of
this new system is to provide children with cash alternatives that cannot profitably be stolen. To
ensure that the cards are worthless to thieves, each card will bear its owner’s picture, so staff at
cafeteria checkouts can easily identify stolen cards.

Which of the following, if true, would most seriously undermine the ability of the card system to achieve its goal?

A. As a result of the cards’ introduction, the number of students who purchase food from school
cafeterias is expected to increase.
B. The replacement of cash with the electronic cards will not allow any reductions in staffing for the
checkouts at the schools’ cafeterias.
C. Staff at the cafeteria checkouts know by name many of the students who regularly use the cafeteria,
and the cards will bear the owner’s name as well as his or her picture.
D. The cost to the school system of issuing the cards and installing the checkout machines to read them will
be covered by the savings arising from no longer needing to handle cash.
E. The companies operating vending machines in the schools are adapting their machines so that the electronic
cards can be used for purchases.

C says (i) staff know many of the students by name, and (ii) the cards bear names and pictures
of the owner. Isn't this factor enough to undermine the ability of the card to achieve its goal?
D: talks about costs Vs benefits to the school authority- the initiator of the project. Its is a very
important factor; otherwise, the school will run at a lose.
E: Of course, the vending machines ought be useful for card operation.

In all C, D, and E remain potential contenders. Can someone provide insight as to which is the best
of the 3?

E for me.
A - strengthening the conclusion and also sounds irrelevant to the issue at stake (which is less money stolen from kids).
B - irrelevant. We don't care how this change impacts staff (only kids).
C - irrelevant at the same time strengthening the conclusion with the assumption that the new cards will have names and staff can confirm that the picture corresponds to the name, as well.
D - Out of scope. We don't care about cost imposed on the school. Even if we did and it cost too much, it still does not weaken the conclusion directly that the plan will fail.
E - CORRECT. If vending machines are incompatible with the new cards, then purchases cannot be tracked. This means that cards are useless, which means that issue of using cash still exists. Hence, plan fails.

Yes, the objective does not focus on the benefits to the school authority.
So, D should be out.

What does the statement mean:
"to provide children with a cash substitute that CANNOT PROFITABLY be stolen"

Why do you think is wrong?
If staffs are unable to recognize students based on the pics + names match, won't that be a problem?

Meanwhile, OA is

Hii Gmatbull.
To answer your last question, the keyword is "many" in option C. Since the staff members know many of the students by their name, it will be very difficult for thieves to get away with purchases because there is a high chance that they will be caught.

Now the answer to your first question is, IMO, that the stolen card may not yield profit to the thieves. This is what I feel and certainly should be in IMO.

Hope that helps.
