Advances in photocopying technology allow criminals with no printing

Approach
(1) Breakdown the arguments from the passage:
1. criminals with no printing expertise can counterfeit paper currency due to Advances in photocopying technology.
2. standard anti counterfeiting technique, is microprinting  where paper currency is printed with tiny designs that cannot be photocopied distinctly.
3. Experts can detect counterfeits of micro printed currency but they often circulate widely before being detected.
4. A costly alternative will be printing with a special ink. What gives? change color depending on how ordinary light strikes it, whereas photocopied counterfeits of such currency would not. (main selling pt of the passage)

(2) What does the question ask? what most undermines the argument
(A) The longer the interval between the time a counterfeit bill passes into circulation and the time for counterfeit is detected, the more difficult it is for law law enforcement officials to apprehend the counterfeiter.
> you can add this to arg3, but it is undermining nothing.
(B) Sophisticated counterfeiters could produce currency printed with the special ink but cannot duplicate microprinted currency exactly.
>> boom! your costly ink ad goes to nothing. like the scammer guy could just buy the ink bro.
She def undermines, no cap G. i mean B✅.
(C) Further advances in photocopying technology will dramatically increases the level of details that photocopies can reproduce.
> Goes with arg1, but is not undermining the main ad that the passage is selling (buy the costly ink bro)
(D) The largest quantities of counterfeit currency now entering circulation are produced by ordinary criminals who engage in counterfeiting only briefly.
> 😱😱😱. ok. goes with arg 3 but not undermining still.
(E) It is very difficult to make accurate estimates of what costs to society would be if large amounts of counterfeit currency circulated widely.­
> This is trying to null + add (funny) to the passage's selling pt about costly ink alternative. one can add this right btw arg3 & 4; but effectively does not undermine the selling point of the passage.

TLDR: Check the conclusion drawn post reading the passage (go for costly ink lads). then check the statement that undermines this (man the guy can just buy this ink then. so yea the pr marketing didnt crack me bro).
