"By applying optimization techniques commonly used to plan operations" needs to correctly modify who is applying these techniques; hence "a company's managers...

E I feel is wrong because the second clause has a "these", a pronoun that has no proper antecedent...

option "b" is incorrect because "its" has no clear referrent , hence e is right . here "its" wrongly refers to company's products instead of company

I will go for B as well. the antecedent of its is company's. Its is a possessive adj so it can refer back to another possessive adj.

I am going for A, simply because all other options have included "manager". What is the guarantee that managers are who are supposedly planning operations? Aren't we unnecessarily introducing a new term?

Just a BIG guess.

"By applying optimization techniques commonly used to plan operations" should modify "managers" who can apply the techniques, that eliminates A,C,D .

between B and E . E can be eliminated because of "these" which has no antecedent and lack of parallelism "both the short and long term".
So , B is the answer.

Hi There,

By applying optimization techniques commonly used to plan operations, it is possible to determine how much effort ought to be devoted to each of a company’s products in order to meet its goals in both the short and long terms.

Well, you are right that the correct answer choice (Choice B) includes an alien term “manager” which is not present in the original sentence. However, we must not just eliminate an answer choice just because it has a new word. We must evaluate the role of that word in the sentence. If the word enhances the meaning of the sentence, then we should accept it. If the new word introduces an error in the sentence then it is certainly a nuisance. Get rid of it.

In this sentence, introduction of “manager” is actually enhancing the sentence. The opening modifier now has a better entity to modify. It is clear that by applying... techniques, company’s managers can achieve something.

Choice A also has parallelism error also. Notice “both the short and long terms”. Here we have two markers, “both” and “and”. Both the markers must be followed by the same entity to maintain parallelism. “both” is followed by “the”. However, there is no “the” after “and”. To make it parallel, we need either “both the short and the long terms” or “both short and long terms”.

Hope this helps.
Thanks.

The essence of a dangling modifier is the absence of the modified noun and we are required to bring it into the sentence, although it may not be there in the original. For example:

After frying in the pan, the entire lot of fish was eaten.

Who ate the fish? This is tricky and GOK; so this is a defective sentence. Now let’s make it more sensible by introducing a new factor namely the doer of the action or the modified noun of the participial modifier after frying in the pan.

After frying in the pan, the cook ate the entire lot of fish.

Now this sentence is better. Thus in dangling modifier cases, the introduction of the doer turns the sentence meaningful and straight. This is how the term manager has crept in royally and grammatically in the correct choice in the given text

b. a company’s managers can determine how much effort should be dedicated to
each of the company’s products in order to meet its short and long term goals
--> In this answer choice what is the antecedent for pronoun "its"?

e. managers at a company can determine how much effort ought to be dedicated to each of
these products in order to meet the company’s goals in both the short and long term
--> "these products" is refering to managers and not company, so dont think that right....

It's between B and E.

But what does 'its' refer to - company's managers or company's products - both are plural. I dont see "company" out there in option B.

E has "these".

I was also between stuck in the end between B and E but then E was knocked because of the parallelism error in both the x and the y, however, I want to understand isnt it referring back to Company and then I remember reading about possessive poison.

Hi there,

This is the sentence with Choice E:

By applying optimization techniques commonly used to plan operations, managers at a company can determine how much effort ought to be dedicated to each of these products in order to meet the company’s goals in both the short and long term.

In this sentence, along with the parallelism issue that you have mentioned, “each of these products” has no reference. What are these “each of these products”? Does the sentence contain a list of products to which this phrase can be referred? No. This reference error makes choice E incorrect.

Now let’s analyze the sentence with choice B:

By applying optimization techniques commonly used to plan operations, a company’s managers can determine how much effort should be dedicated to each of the company’s products in order to meet its short and long term goals.

Pronoun “its” is a possessive noun. This means it must refer to a possessive noun. There is only one possessive noun in the sentence – “company’s”. So without any ambiguity, possessive “its” is referring to “company’s”. If we replace “its” with “company’s” we get the logical intended meaning of the sentence:

By applying optimization techniques commonly used to plan operations, a company’s managers can determine how much effort should be dedicated to each of the company’s products in order to meet company’s short and long term goals.
Hence, this choice is error free.

Hope this helps.
Thanks.

Thanks for detailed explanation. However, in Choice B:
"By applying optimization techniques commonly used to plan operations, a company’s managers can determine how much effort should be dedicated to each of the company’s products in order to meet its short and long term goals."

--> I think the "company's" in this sentence plays the role of possessive adjective, hence, can't be consider as antecedent of "its".

Quote from GMAT Manhattan:

" The board is investigating several executives' compensation packages in order to determine how much may have been improperly awarded to them"[color=#ed1c24][/color]
--> This is considered WRONG because "them" cannot refer to "executives' ".

can you help to explain and differentiate these 2 cases?
