    TOEFL question

    This is a "Choose the wrong answer" question from a sample TOEFL test. "Production of chlorine A. without the attendant sodium hydroxide is attained by the electrolysis B. of fused chlorides such as lithium or magnesium and C. several different chemical processes such as D. the reaction of sodium chloride and nitric acid." According to the answer key, "C" is the wrong one. But I can't see anything wrong with all the underlined phrases. I need help from a teacher. Thanks in advance.

    Re: TOEFL question

    The only thing I can see is that C refers to several different chemical processes but D mentions only one.

    I can't see a mistake there.

    Re: TOEFL question

    Nor can I. The only potential amendment I could make would be to add the word "by" at the beginning of section B. It is perfectly acceptable without "by" though. Unless there is an error in the chemical side of this (which would be entirely unfair in an English test), then I can't see an error.

    Just to make sure, I have removed the letters A, B, C and D and the formatting. This is the sentence it leaves:

    Production of chlorine without the attendant sodium hydroxide is attained by the electrolysis of fused chlorides such as lithium or magnesium and several different chemical processes such as the reaction of sodium chloride and nitric acid.
    Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.

    Re: TOEFL question

    Is it an official test? Official tests are tested repeatedly for errors, so mistakes are very rare indeed, but where people write tests similar to the official ones, mistakes can occur.

    As I said in post #5, the only suggestion I could make would be to add the word "by" at the beginning of section B, but it's not obligatory.

    Re: TOEFL question

    Did you mean C? There is already a "by" before B in the body of A.

    Re: TOEFL question

    Sorry, yes, I meant at the beginning of C. Both times!
