5/29 Identifying Sentence Errors

The following sentence contains either a single error or no error at all. If the sentence contains an error, select the one underlined part that must be changed to make the sentence correct. If the sentence contains no error, select choice E. 

For Identifying Sentence Errors questions, always read the sentence and focus on anything that sounds strange or wrong. Determine whether that part of the sentence is actually incorrect, then identify the part of the sentence that, if changed, would correct the error. Double-check that the other sections of the sentence are correct as they are, and finally mark the correct answer on your answer sheet.


Besides conserving forest resources, recycling produces fewer pollutants than does the conventional pulping and bleaching processes that are normally used to create paper. No error


First, read the sentence carefully and try to see if anything sounds wrong to you. If you have a good ear you may notice that B sounds a little strange. In order to confirm the error look at the verb does and see what the subject is. In this case it is the "conventional pulping and bleaching processes" that the verb refers to. Since our subject is plural, the singular form of the word does does not fit in the sentence. 

Answer choice A is a participle (a verb that acts like an adjective) inside of a prepositional phrase ("Besides... resources"). It is used correctly. 

Answer choice C uses the word that and that is correct since the part of the sentence that follows is essential to the meaning of the sentence (if it could be omitted, the sentence would have used the word "which" preceded by a comma:  "…processes, which").

Answer choice D is an infinitive verb correctly used immediately after a normal conjugated verb. 

The correct answer is choice B.
