a. and sinking 
b. and sinking them

Senthil1981 · Answer

i'm going with C

marine engineers are not going to sink - Eliminate
 
them is plural, and marine engineers want to sink the aritifical reef, which is singular.- Eliminate
 
Correct singular pronoun usage.
 
it doesnt sink, someone is sinking it - Eliminate
 
simply awkward.

No, The meaning of the sentence is towing old barges and sinking old barges to the sandy bottom. hence, answer should be B. Here, them clearly refers to old barges.

Shiv2016 · Answer

When should we repeat words in parallelism? 
As in this case, will this be correct: by towing........and by sinking..........

daagh · Answer

Just as there is an object, old barges, for towing, the sinking also should be followed by an appropriate object, 'barges', or 'them'. Otherwise, it would mean that the marine engineers are towing and sinking themselves

mba757 · Answer

a. and sinking
 (1) what is sinking? Is it the “old barges” or is it the “engineers” themselves?

b. and sinking them
 best option

c. and sinking it
 (1) it = SV disagreement; we’re referring to the “old barges”

d. where it sinks
 (1) it = SV disagreement; we’re referring to the “old barges”; (2) meaning error = the act of (intentionally) sinking is removed within this option, changing the meaning the original sentence

e. having sunk them
 (1) sounds like the sinking comes from the towing, illogically

DexterZabula · Answer

daagh   mikemcgarry

How do we determine whether the engineers are sinking the barges or reef?
Moreover, do we really think that sinking barges (boat) will restore fishing ground?
It's the reef that will attract fishes, raising fishing probabilities.
How will the sinking of a boat help in this case?

BLTN · Answer

Dear experts,
could you enlighten, does 2 actions happened at the same time; how is it possible to fulfill two action simultaneously?
"...by Towing old barges to an offshore location AND Sinking them"

Would it be clear to add then after conjunction "and" ?

Thanks beforehand.

EducationAisle · Answer

Yeah...but I think we have to leave some of it to imagination and common sense

. For example: Every morning, Peter wakes up and goes for a walk . Obviously, waking up and going for a walk, don't happen simultaneously.

ExpertsGlobal5 · Answer

Hello  BLTN ,

We hope this finds you well.

To answer your query, this sentence does not indicate that these two actions happen simultaneously; the sentence merely conveys that marine engineers can create an artificial reef by taking two actions - towing old barges to an offshore location and sinking the barges to the sandy bottom.

We hope this helps.
All the best!
