Sasha:
handwriting analysts think their analysis is more reliable than it is.
handwriting analysis should be banned in a courtroom
Greg:
they think it's more reliable than it is because they're irresponsible
professional standards will eliminate this
this would make handwriting analysis legit
irresponsible analysts claim their work is way too reliable
official standards will see these people out (and let in responsible ones who claim more honestly?!)
assuming responsible analysts make reasonable claims or believe in their work in general as reliable evidence
at first glance (d) came off as agreeing with greg's statements
but this also infers that responsible analysts don't believe in it as reliable evidence
that would be problematic on greg's suggestion
(c) was tempting but i couldn't deduce/infer anything from it solid enough to place a burden on greg's claim, which made me uneasy and led me to pick (d) but with a bit of uncertainty!
