Question

According to Duverger&rsquo;s law, countries with single-ballot majoritarian elections for single-member districts tend to polarize into two-party systems, wherein dueling political parties consistently dominate the political system. ______ blank countries with proportional-representation electoral systems tend to support multi-partyism, under which power gets distributed among many political parties. Which choice completes the text with the most logical transition?

Accepted Answer

Choice B is the best answer. "Conversely" logically signals that the information in this sentence-that countries with proportional-representation electoral systems tend toward multi-partyism-contrasts with the previous information about countries with single-ballot majoritarian elections, which tend to have two-party systems. Choice A is incorrect because "subsequently" illogically signals that the information in this sentence about countries with proportional-representation electoral systems occurs later in a chronological sequence of events than the information in the previous sentence. Instead, it contrasts with the previous information. Choice C is incorrect because "for instance" illogically signals that the information in this sentence about countries with proportional-representation electoral systems is an example supporting the previous statement about countries with single-ballot majoritarian elections. Instead, it contrasts with the previous statement. Choice D is incorrect because "in other words" illogically signals that the information in this sentence about countries with proportional-representation electoral systems is a paraphrase or restatement of the previous information about countries with single-ballot majoritarian elections. Instead, it contrasts with the previous information.
