This question has moderate difficulty. Sentence 3 undoubtedly serves as the best start for the paragraph. Following 3, sentences 1 or 2 are both plausible as they both discuss the creative element. However, examining sentence 4 provides a clearer idea of the correct sequence. Sentence 4 states, 'it is for this reason that today’s trade issues are increasingly involving intellectual property rights.' Why would companies seek intellectual property? The answer is to gain a competitive advantage over their rivals. Thus, sentences 1 and 4 form a pair. The correct sequence should be 3214, where 2 should come after 3 to maintain the 31 pair, and not be placed at the end. Its best position is after 3.
