43. 【答案】G  There is a better way to win arguments.

【解析】 根据已经给定位置的F项，F句末出现了“None of these tricks will help you understand them, their positions or the issues that divide you, but they can help you win — in one way.”中有“help you win-in one way”，而G段首句“There is a better way to win arguments.”的“a better way to win”是对“help you win-in one way”的递进。因此G段在F段后面。
