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).

• A-E: Logically and grammatically sound. The singular subject ("collapse") aligns perfectly with the past tense verb ("sent"), accurately describing the financial aftermath of an exchange failing. • B-F: Grammatically correct. The introductory prepositional phrase expressing purpose ("In an effort to curb...") is perfectly followed by the main clause detailing the action taken by the "central monetary authority." • C-D: Contextually and grammatically flawless. The singular subject phrase ("The relentless expansion") correctly takes the singular verb phrase ("has led"), forming a meaningful sentence about ecological consequences. All three pairs are correct.
