The new filling machine, which was installed and commissioned last week, fills twice as much vials in a minute as the old machine, which was decommissioned last year, has.

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.

D. as many as twice the vials that the old machine, which was decommissioned last year, has.

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.

Let's spot the errors in the original sentence, shall we?

Firstly, using 'much' for a countable noun is blasphemous. Secondly, the usage of 'has' is incorrect. It should be 'did' or 'filled'. For these reasons, option A is incorrect.

Option B uses 'double - than' which is kinda unidiomatic? At least, as far as I know, 'more-than' and similar usage is idiomatic. At least, this is the reason why I threw B in the trash

Option C: this option seems error free. Let's hold on to this option for now

Option D: Again, 'has' is incorrect

Option E: 'than' is bothering me here as well. Moreover, two times than?

Option C is where I'll place my bets. That's the right answer.

1.Usage of twice/Double----> Twice adverb , double adjective

2.Vials are countable noun ---------> many
3. Usage of has is wrong.
A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.-- Due to 2 & 3- Incorrect

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.-- That can't replace the words fills ..vials in a minute . Wrong parallelism. Incorrect

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled. Grammatically correct but E is better worded.

D. as many as twice the vials that the old machine, which was decommissioned last year, has. - Again due to error pointed in 2&3

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled. Correct

IMO C


A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.-- vials are countable so 'much' is not right

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.- double the vial ... than that the old machine is incorrect

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.- Correct error from A has been corrected

D. as many as twice the vials that the old machine, which was decommissioned last year, has.- has in the end is inappropriate

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled. - twice as many is better over two times

Looking at the answer choices we see beginning splits "twice", "double" and "two times", and ending splits "has", "did" and "filled". Since old machine "was decommissioned last year", clearly the verb "has" incorrect, it should be in past tense. So A and D are out. "double .... than" and "two times ... than" forms are incorrect. So C is the winner

the correct answer is C
choice A is wrong because vial is countable we use many
choice B is wrong because comparison between two machines and not between vials
choice C no mistakes
Choice D is wrong because "as many as twice " is wrong
Choice E is wrong because we fill vials and not time.

Thank you sayantanc2k for the question!!!


A. twice as much vials in a minute as the old machine, which was decommissioned last year, has. WRONG.

- The vials are a countable noun - we cannot use much.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did. WRONG.

- double introduces quantity - changes the intended meaning
- double THAN that is wrong - double that of or double of what is better.

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.

CORRECT. FILLS twice as many vials as the old machine FILLED.

D. as many as twice the vials that the old machine, which was decommissioned last year, has. WRONG.

-twice the vials that the old machine HAS. HAS introduces possession. The old machine does not HAVE the vials, rather it fills.

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled. WRONG.

- two times THAN is wrong. two times MORE THAN would be better, besides it would stray from the intended meaning.

I go with B
A. twice as much vials in a minute as the old machine, which was decommissioned last year, has. Old machine filled in the past

B. double the vials in a minute than that the old machine, which was decommissioned last year, did. Correct

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled. did is better than filled

D. as many as twice the vials that the old machine, which was decommissioned last year, has. same mistake in A

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled. awkward

1. twice vs double vs two times
Twice is preferred over the other two options
2. as much vs as many
Since vials can be counted, "as many" should be used
3. has vs did vs filled
Has is the worst of the three options because the old machine was decommissioned last year.

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.
--as much and has

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.
twice as many > double
filled > did

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.
--Correct

D. as many as twice the vials that the old machine, which was decommissioned last year, has.
--has

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.
--twice as many > two times

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.

Firstly, it should be 'many' (countable noun) not 'much' (non-countable noun). Secondly it should be filled, since the old machine has already been decommissioned in the past, and the decommissioning is not continuing in the present.

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.

Vials is a countable noun, hence use of much is incorrect.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.

Should be double the number of vials.
use of did is incorrect


C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.

This seems correct.

D. as many as twice the vials that the old machine, which was decommissioned last year, has.

Should twice as many as

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.

Use of two times and than is incorrect.

IMO C

Thank you sayantanc2k for the question!!!

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.

As much as for countable noun is incorrect. Use oh Has (present perfect) for some action of machine that has already decommissioned.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.

Use of double with than is incorrect. Ex- we say Machine fills double the bottles old machine did.

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled. Correct

D. as many as twice the vials that the old machine, which was decommissioned last year, has.

Use of Has error as in A

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.

Same error as in B. use of than with two times

[quote="Bunuel"]The new filling machine, which was installed and commissioned last week, fills twice as much vials in a minute as the old machine, which was decommissioned last year, has.

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.
-use of as much vials is incorrect. Vial is a countable noun.Thus many should be used instead of much.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.
-use of double is incorrect. double is incorrectly modifying vials
C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.
-This is the correct option. twice as many vials represents the number of vials correctly
D. as many as twice the vials that the old machine, which was decommissioned last year, has.
-Use of has is incorrect. The old machine is not working. So we should use past tense
E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.
-two times the vials is incorrect. modifier usage is incorrect

The new filling machine, which was installed and commissioned last week, fills twice as much vials in a minute as the old machine, which was decommissioned last year, has.

A. twice as much vials in a minute as the old machine, which was decommissioned last year, has.

B. double the vials in a minute than that the old machine, which was decommissioned last year, did.

C. twice as many vials in a minute as the old machine, which was decommissioned last year, filled.

D. as many as twice the vials that the old machine, which was decommissioned last year, has.

E. two times the vials in a minute than the old machine, which was decommissioned last year, filled.

(A) as much for countable is wrong usage
(B) double 'the' vials -- here 'the' vials atecedent reference is not clear
(C) correct usage of 'as many as' is the correct idiomatic structure
(D) as many as twice --awkward structure; also tense error with 'has' usage in the end
(E) 'two times__than the old machine' is an incorrect idiomatic strucure

Hence, (C) is correct option
