What was the most important success of GATT?
A、It promoted trade between its member countries.
B、It greatly promoted the productions of its member countries.
C、It reduced the trade disputes between its member countries.
D、Throughout the GATT era it helped ensure that trade growth out-paced production growth.
【正确答案】：D
【名师解析】:正确答案是D。GATT（General Agreement on Tariffs and Trade，关税及贸易总协定）的主要成功在于它在存在期间确保了贸易增长超过了生产增长。GATT通过降低关税壁垒和减少非关税贸易限制，促进了国际贸易的自由化和扩大。这种贸易的增长不仅增加了各国的经济效益，而且也有助于全球经济的稳定和增长。选项A、B和C虽然也是GATT的一些成果，但它们并没有像D选项那样全面地概括了GATT对全球贸易的长期影响。
