Several consumer protection agencies have filed suit, seeking to bar distributors from advertising treatments for baldness that brings no discernible improvement and may even result in potential harm.


(A) that brings no discernible improvement and may even result in potential harm


(B) that bring no discernible improvement and may even prove harmful


(C) bringing no discernible improvement and even being harmful


(D) that brings no discernible improvement and may even potentially result in harm being done


(E) that bring no discernible improvement, maybe even resulting in harm



This question is based on Subject-Verb agreement and Modifiers.


The underlined portion is a modifier that provides information about the subject 

‘treatments’. The relative pronoun ‘that’ refers to ‘treatments’ and not to ‘baldness’ even though it is placed immediately after the word. It is the treatments that bring no discernible improvement. So, the verb ‘bring’ also agrees with ‘treatments’ and should be in the plural form. 


Options A and D contain the singular form of the verb – brings. They are also wordy options. So, Options A and D can be eliminated.


In Option C, the modifier is in the form of a participle phrase that is parallel to the other modifier “seeking”. However, this changes the meaning of the sentence because “seeking” modifies the subject “several consumer protection agencies”. The meaning thus conveyed is that the consumer protection agencies are bringing no discernible improvement and even being harmful. Since this is illogical, Option C can be eliminated.


In Option E, the participle modifier “maybe even resulting in harm” seems to modify the subject “several consumer protection agencies”. However, it is the treatments that may even result in harm as the phrase placed just before the modifier indicates. So, Option E can be eliminated. 


In Option B, the verb ‘bring’ agrees with the subject ‘treatments’ and the modifier modifies the same subject. Therefore, B is the most appropriate option.
