Let's take a look at the list:

Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced
(a) sickness,
(b) sleeping on the job,
(c) fatigue among shift workers,
and
(d) have raised production efficiency

The first three are nouns, and make sense with have reduced (have reduced sickness, have reduced sleeping, have reduced fatigue), but after that, we run into a verb phrase (have raised...) instead of a noun, and we end up with have reduced have raised production efficiency as the final element in the list.

But I think have is used to make things parallel.

Need some more input.

Hi Harsh2111s,

That's one way of looking at it, but then we'd really need two lists, which would in turn mean that we'd expect to see two conjunctions in the sentence.

Equations have reduced (X, Y, and Z), and have raised (B).

To see why it'd be much better to include the second conjunction, check if you'd be comfortable with the following sentence:

Equations have reduced X, Y, and have raised B.

Will it be correct if the sentence structure in A is as below

'have reduced X,Y and Z and have raised'

Can someone please clarify?

Hi NimishaKrishna,

Doing that would certainly remove that particular error, but it is hard to say whether option A would then be "correct". Generally, we should avoid evaluating altered options, because we'd then be going by our own opinions, instead of those of the GMAT.
