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. Vials are countable - therefore using “much” is wrong; “”many” should be used instead. Use of the verb “has” is wrong. Here “has” is a part of the compound verb “has filled”, but the word “filled” is wrongly committed. Omission of a word is allowed when the word already occurs in the sentence - here the word “filled” does not exist in the sentence.
B. The word “than” is wrongly used. The word “than” must always be used with a comparative adjective, but in this sentence there is none.
Use of the verb “did” is wrong. Here “did” is a part of the compound verb “did fill”, but the word “fill” is wrongly committed. Omission of a word is allowed when the word already occurs in the sentence - here the word “fill” does not exist in the sentence.
C. CORRECT. “Many” is used to depict a countable noun. The verb “filled” is used in past tense correctly. Parallelism is maintained between the two elements compared.
D. Use of the verb “has” is wrong. Here “has” is a part of the compound verb “has filled”, but the word “filled” is wrongly committed. Omission of a word is allowed when the word already occurs in the sentence - here the word “filled” does not exist in the sentence.
E. “Two times” is wordy. The word “than” is wrongly used. The word “than” must always be used with a comparative adjective, but in this sentence there is none.
