In each of the following questions, two columns are given containing three sentence fragments each. In the first column, the fragments are labelled A, B, and
C. In the second column, the fragments are labelled D, E, and F. You are required to match the fragments from Column I with the fragments from Column II to form grammatically correct and contextually meaningful sentences. Choose the option that provides the correct combination(s).

• B-D: Forms a complete, coherent sentence. The singular subject "dismantling" correctly agrees with the singular verb "has marginalized," creating a logical statement about the social impact of removing public transit. • Why A-F fails: Grammatical error. The conjunction "While" sets up a contrast that needs a proper independent clause. However, the phrase "it ultimately failing" uses a present participle instead of a finite past tense verb. It should be "it ultimately failed to generate..." • Why C-E fails: Subject-verb agreement error. The subject of the sentence is the gerund phrase "Harnessing the power..." which is singular. Therefore, the verb in Column II must be singular ("requires"), not the plural "require."
