【正确答案】 A

【答案解析】判断题。本题需要根据上下文推断出 be brought forward 这一词组的意思。在“A break-through in the pro- vision of energy from the sun for the European Economic Community could be brought forward by up to two decades...”一句中，be brought forward 的动作的对象是 a breakthrough (突破)，同时 be brought forward 的程度是by up to two decades，由此可判断be brought forward 应具有“使一种突破提前多至20年实现”的意义，四个选项中只有选项A be advanced与此意义相近，故选项A为正确答案。“A breakthrough could be expected/be introduced/ competed by up to two decades”在意义上不通，故选项B、C和选项D也不正确。
