Why is A correct? Why is D incorrect?

I think the key here is to note "new" and "existing" in the stimulus. If there's a new, more productive way of working, then there will be in increase in efficiency (NMPWW -> IE). But since the computer system is is fitting the existing way of work (~NMPWW), then it would have to be the case that there is not an increase in efficiency (~IE, answer choice A).

I read "most logically completes the argument" as a statement that would make the contrapositive statement " ____ -> ~NMPWW" true. Since the contrapositive of the S&N in the first sentence would be "~IE -> ~NMPWW", I think that would justify why (A) is correct.

@Ryan-Mahabir and @Julie-V,

Here, the stimulus is actually telling us something else: if a new system doesn't force employees to adopt new/better ways of working, then it won't significantly increase efficiency. (if ~FEANWW, then ~SIE)

We know that the new system will fit the existing ways of working. In other words, it won't force employees to adopt new/better ways of working. We can see that A results from our conditional logic. Hope this helps!

Is "appreciable" the same as "significant"?
