i think that one thing that math class teaches you about "measurement" is
that there is error ... well maybe they do, now that i think of it, i am
not so sure how clear this notion is taught ... but, let's assume that it
is ...
math would also reinforce meaning of the use of the english ( ____ input
other language if appropriate) language ... the term "accurate" does have
some meaning ...
in this context ... and after all, every item is in some context ... it
says accurate for BOTH ... to the nearest foot
so, i think a perfectly legitimate interpretation of that is ... could be
off 1/2 foot down ... or up ...
i don't see anything mathematically wrong with deducing the answer to be C
given the context of the item ...
so, if you are saying that C is the best in this context ... good ... if
you are arguing for D ...
i disagree
my math is not great ... but, it ain't that bad either
