A questionable assumption of the plan is that
A in the territory served by the banks the proportion of counterfeit checks that are made using electronic scanners has remained approximately constant over the past few years
B most counterfeiters who use electronic scanners counterfeit checks only for relatively large amounts of money
C the smallest dots on the proposed checks cannot be distinguished visually except under strong magnification
D most corporations served by these banks will not have to pay more for the new checks than for traditional checks
E the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future
Let's break down our passage.
1. printers/scanners make faking checks easier
2. to deter fakes, banks will issue small-dot checks
3. scanning/printing small-dot checks doesn't work
We're asked to identify an assumption of the plan, and as the logic given in the passage is extremely clear, we'll first try to infer it and only then look to the answers.
This is a Precise approach.
In particular, there are 2 main claims. The first is that the small-dot checks will deter fakes. This assumes that, currently, fakes are created by scanning and subsequently printing existing checks, which is nowhere mentioned in the passage and is therefore a likely answer. The other main claim is that today's printers are technically unable to scan and print the 'small-dot' checks. For this to be relevant, we need to assume that tomorrow's printers won't be significantly better than today's.
Looking over our answers, (E) is equivalent to the second assumption we identified and is our best answer.
Hi David,
I am not able to digest this. Could you please help me here?
The question asks for a questionable assumption.
Let's break the argument.
• The general availability of high quality ES and CP has made CF easier
• Several Banks plan to issue to their C Banks customer checks that contain dots too small
• These dots are too small to be accurately duplicated by
"any electronic scanner currently" available.
• When checks are scanned and printed,
• The dot seems to blend together in such a way that the word "Void" appears.
Now,
As per the plan, the Banks want that the counterfeiting should not happen.
i) In future no electronic device will come up to scan this
ii) The "VOID" can be seen even if the checks are duplicate
a. Meaning while passing checks, there is no requirement for check with precision.
Now if we negate the second pre-assumption, we come up with option C, which says that the naked eye can't detect the difference. Is it not questionable? Please help….
