OA is E. D swaps subject verb order. i.e. is the inventory instead of the inventory in E.

Also in option D, frequently and often have same meaning.

IMO E

I feel answer should be either (A) or (B).

Can anybody write why these are wrong.

What is OA?

'Turns over' or 'turned over' is correct .A & B use 'turnovers'.

Maintaining parallelism, "How" does not fit into the options A,B,C.
Option "D" seems to be asking a question to main subject of sentence "supermarket industry". Better option seems to E.

D option has a couple of issues:

The 'how frequently" clause is started by how, a relative pronoun, so the sequence is: subject + (auxiliary) + verb . If it is a independent question, started by a interrogative pronoun, the sequence is how + auxiliary + subject + verb.

Often is not redundant with "frequently", because they are referring to different things. But "often" really changed the meaning of original sentence.

I am confused whether we shud go for turnover / turns over ...
Turnover - an act or result of turning over; upset

If turnover is the right then it shud be option A.

moreover abt parallelism

It is well known in the supermarket industry that how items are placed on shelves and the frequency of
inventory turnovers can be crucial to profits.

that how is nt it parallel to both the sentences before and after 'AND' , so why do we shud repeat how again after 'AND'


Please let me know if I am wrong

what is OA?

OA answer is E I thought D is out for redundant are often. Can anyone give a detailed explanation ?

(A) the frequency of inventory turnovers can be
(B) the frequency of inventory turnovers is often
(C) the frequency with which the inventory turns over is often
(D) how frequently is the inventory turned over are often

Parallelism:

How X and how Y--is the parallelism tested in this sentence.
==> This rule helps us eliminate A, B, and C.

We are between D and E. In the option D, "How frequently is the inventory turned over" has a problem. We normally use auxiliary verb(s) before subject in case of interrogative sentence. The option D could be correct is it were "How frequently the inventory is turned over". Again two clauses have been connected, and a compound subject has been made. It is not correct. We are finally left with E, the best answer.

Thanks.

inventory turnovers can be crucial to profits.

(A) the frequency of inventory turnovers can be
(B) the frequency of inventory turnovers is often
(C) the frequency with which the inventory turns over is often
(D) how frequently is the inventory turned over are often
(E) how frequently the inventory turns over can be

First: Parallelism=> How x and how Y is the paralleism. We can eliminate the option A, B, and C.

We are left with D and E.

In the option D, "how frequently is the inventory turned over" is a problem. We know, auxiliary verb is usually used after subject. In case of interrogative sentence, we use auxiliary verb before subject. In the option D, the auxiliary verb "is" has been wrongly used before verb. We are left with E.
Answer is E.

excellent gmat_perfect .little correction i think :

In case of interrogative sentence, we use auxiliary verb before subject. In the option D, the auxiliary verb "is" has been wrongly used before verb. We are left with E.

bolded part should be "before subject" not "before verb" .

Hi Guys, really struggling to understand the face-off between "D" and "E" . Could anyone explain this differently.
Also isn't the second part of "E" wrong in the sense :

It is well known in the supermarket industry that how items are placed on shelves and the frequency of
inventory turnovers can be crucial to profits.

(D) how frequently is the inventory turned over are often
(E) how frequently the inventory turns over can be (doesn't it mean that the inventory turns over by itself)

Example:
(E) how items are placed (by someone) and how ... inventory turns over (by itself ?)
