Hi Noboru,

in D choice...'their' can have 2 antecedents.
their --> farmers
their --> cows

So hw D can be ans
plz correct me if I m wrong.


there is no ambiguity: "cows" is part of the possesive cows' milk, so "their" clearly refer to the subject, which is farmers.
Please let me know if that helped.

why?


The reason why it has to be farmer and not engineer is that by installing, farmer is achieving something. It's not engineer who is achieving.

Engineering would have been correct if the sentence was like this:

By installing electric pump at farm for the first time, engineer learned to install a pump without supervision.

It's Modifier and meaning problem

Either of farmer and engineer can be subject here. But keeping 'Engineer' as subject will change the meaning of the orginal sentence.

Is it necessary that the starting phrase in thuis case "by installing ... pumps " has to modify the subject of the sentence ?


just ask yourself a logical question "who will benefit by installing the pumps?". clearly, the farmers and not the engineers.

Modifier problem. Present participle (installing) in the first clause needs its subject in the beginning of the successive clause. In this case it is "farmers". D wins.

Straight 'D' in 8 secs :-)

Modifier issue and only 'D' fixes the issue. Whenever there is a inverb such as 'installing', i.e. ending with -ing, look for modifier issues (Thank you GMATPill for this tip :-) ).

By installing special electric pumps is clearly modifying the subject FARMERS , thus D is the correct choice.

(D) farmers, according to one agricultural engineer, could use the warmth from cows’ milk to heat their houses

Here Cows' are possessive noun and hence theirs should be used for cows'.Therefore Their has a clear antecedent,which is farmers.

the answer should be D no doubt in it .
Their can only refer to the farmer .Its cows'(possessive) and not cow .

it is between C and E. yes it is modifier problem ... electric pumps ...who installs? an engineer ..

so I go with C for clarity and active voice.


i think you mistook, actually engineer is reporting, only farmer installs ..



Who installs whatever.....
Who knows.....? Farmers are beneficial.....???? Who cares, the subject has to be beneficial

What if the engineer has to report after installing and verifying, I seriously don't know the practicality behind these actions...

However, I hope such ambiguous(even partially) q's don't come.

I don't say D is wrong either...

Thanks
