A new test for AIDS has proved helpful in eliminating blood, contaminated with the virus, from the nation's blood supply.

o in eliminating blood, contaminated with the virus, from the nation's blood supply
Correct
o in eliminating blood from the nation's blood supply that is contaminated with the virus
Makes it seem that nation's bloody supply is contaminated with the virus
o in eliminating from the nation's blood supply blood that is contaminated with the virus
Was confused about this one, but I think A does a better job is not repeating the word blood. Cant see anything wrong otherwise
o to eliminate blood that is contaminated with the virus from the nation's blood supply
The virus is not from the nation's blood supply!
o to eliminate blood from the nation's blood supply that is contaminated with the virus
Makes it seem that nation's bloody supply is contaminated with the virus

Thus I shall go for A

I guess it's C.

o in eliminating blood, contaminated with the virus, from the nation's blood supply
three clauses that are totally independent.
o in eliminating blood from the nation's blood supply that is contaminated with the virus
Makes it seem that nation's bloody supply is contaminated with the virus
o in eliminating from the nation's blood supply blood that is contaminated with the virus
the use of 'that' clearly says that the blood is contaminated with the virus and not the blood supply - correct
o to eliminate blood that is contaminated with the virus from the nation's blood supply
to eliminate is wrong usage
o to eliminate blood from the nation's blood supply that is contaminated with the virus
to eliminate is wrong usage

i think this explanation is pretty great!

It was tough between A and C, but i think pbanavara explained pretty nicely

In A.. "contaminated with the virus" --> not essential..phrase. if you remove this and read the sentence..
It doesn't make sense.

C --> that clearly introduces essential clause..

C is the best

in eliminating gets precedence over to eliminate and blood supply that is meaningless.
So fight is between A and C.

in eliminating X from Y is good construction. C sounds really bad. There is no problem in A . that is unnecessary here. I will go with A.

Can somebody explain me what is wrong in A.

"in eliminating" is better than "to eliminate"

C is clear & better than other options.

misplaced modifier I think. "That" should be close to blood.

(B) in eliminating blood from the nation's blood supply that is contaminated with the virus ------> don't know what is contaminated. Whether the blood or the supply.

(C) in eliminating from the nation's blood supply blood that is contaminated with the virus ----> blood is contaminated. Of course "eliminating" cannot be contaminated.

i think

A is better because commas are used at the proper place.

C would have been better had there been a comma .
'in eliminating from the nation's blood supply( ,)blood that is contaminated with the virus.'

C) is correct.

Idiomatic usage is "helpful in "
Eg "your help in walking the dog was appreciated."

A contains three clauses all together and this makes them look like independent clauses. A "that" is needed to identify an essential clause.

(C) in eliminating from the nation's blood supply (missing comma) blood that is contaminated with the virus

Resumptive or Summative modifier would need a comma but C does not supply it. Is there a typo in the post?

Excellent! You mean option C, I guess. Yes I agree.

A and B both have modifier issue and C is as close as it gets to OA. Commas are easier to miss.

Another clue that he left is - although I won't trust this 100%. The distance of that

C

Option A has got non-essential modifier whereas blood need essential modifier to point out that which blood need to be removed. In option B that point out to the blood supply. Only in option C both of these issues are rectified.

i want to know what are the 3 independent clauses in A, and how are they independent clauses as has been quoted a few posts above.
1)A new test for AIDS has proved helpful in eliminating blood.
2)contaminated with the virus
3)from the nation's blood supply

1 is an independent clause alright

but how are 2 and 3 independent clauses ?
