A computer equipped with signature-recognition software, which restricts access to a computer to those people whose signatures are on file, identifies a person's signature by analyzing not only the form of the signature but also such characteristics as pen pressure and signing speed. Even the most adept forgers cannot duplicate all of the characteristics the program analyzes.

thanks, this one was pretty straightforward once I realized it's just asking what MUST be true from the passage.
agreed, got it fast too. the word 'solely' in C is what makes it airtight
wait why is C right? I picked E because I thought maybe the software was too strict... can someone explain
E goes way beyond the passage. nothing says authorized users get denied, that's just a guess. C is the only one that follows directly from 'forgers can't copy everything'
sub-505? felt like a freebie. the whole thing is basically handing you C with the forgers sentence
the key is 'solely by virtue of skill at forging.' since even elite forgers can't beat all the traits, skill alone can't get you in. took me a sec on that word
What it tests
Whether you can identify the argument's main conclusion as opposed to a supporting premise.
Common trap
Selecting a restatement of a premise or a side point instead of the central conclusion.
