But then, technically speaking, in B, as it seems to me, its does not have antecedent either - both time we have company's (managers and products), not company...

good point!
I did some research with my MGMAT Book
I got it right
"each of a company’s products" is SINGULAR

'its' is a possessive pronoun that refers back to each of a company’s products (a possessive noun)

Singular--Singular

True, you are right, thanks! Its all about possessive pronouns refering back to possessive nouns, which is ok.

Yes Brother
but even then singular-singular
plural-plural rule still will be applicable

Antecedent and Pronoun Must agree in Number

"each of a company’s products" is SINGULAR

'its' is a possessive pronoun that refers back to each of a company’s products (a possessive noun)

Singular--Singular

I actually think that this answer is wrong since that would mean that "each of the company's product" has a short and long term goal? - this doesn't make sense as opposed to a company that has long and short terms!

IMO the best answer is E even though it has These, B changes the meaning

q10nik, the possessive pronoun "its" here actually stands in for "company's":

Jane's father is going to the store. Her mother is also going to the store. CORRECT (possessive "Her"=possessive "Jane's")

Jane's father is going to the store. She is also going to the mechanic. INCORRECT (The possessive word "Jane's" CANNOT be the antecedent for the subject pronoun "she")

---

The pronoun "these" without an antecedent is a nice way to knock off D and E quickly. Another pronoun issue that no one's mentioned yet is the "it/its" issue. If you use the general "it" ("it is hard to run while balancing a bucket of water on your head") you cannot use "it" again to refer to a different antecedent in the sentence.

a) it (general!) is possible to determine how much effort ought to be devoted to each of a company’s products in order to meet its (specific-- the company's) goals in both the short and long terms

c) it (general!) can be determined by company managers how much effort ought to be devoted to each of the company’s products in order to meet its (specific-- the company's) goals, both short and long term

Therefore A and C are also out.

Based on pronoun issues alone you can lose A, C, D, and E!

"Its" can have either a possessive or a non-possessive noun as its antecedent, but the antecedent has to be singular.
Possibilities are:
company --> singular
managers --> plural
products --> plural
Thus, the only antecedent that "its" can have is "company".

Thanks!

OA is B

I went with B..
by applying x, -> we need a subject here. managers applied smth to get smth else.
A - modifier error as above explained.
B - looks ok
C - boh short and long term - what it refers to? + modifier error as in A. THESE - doesn't have an antecedent
D - introduces a POSSIBILITY - so no. these - again error
E - managers at a company - way wordier. these - again pronoun error.

B looks better. B it is.
