Question
Read the sentence to find out whether there is any
grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The letter of that part is the answer. If there is āNo errorā, the answer is (5). (Ignore errors of punctuation, if any). The most common contaminant (A)/ identified in groundwater (B)/Ā is dissolve nitrogen in the form (C)/of nitrate in sub-surface waters (D) no error (E)Solution
The error is in part (C). The phrase "is dissolve nitrogen" is incorrect. The correct form should be "is dissolved nitrogen", because "dissolved" is the past participle form used to describe the state of nitrogen in the water. The corrected sentence should be: "The most common contaminant identified in groundwater is dissolved nitrogen in the form of nitrate in sub-surface waters."
