Po一道在ECONOMIST GMAT NOTE上看到的题目,还真没完全搞明白 In 1812, Dietrich Nikolaus Winkel inventedthe metronome, which is a device that produces a regulated audiblepulse usually used to establish a steady tempo for the performance of musicalcompositions. (A) which is a device that produces aregulated
(B) which is a device that produces a regular
(C) a device that produce a regulated
(D) which is a device that produce a regulated
(E) a device that produces a regulated
OA:E, 解释说A中的which是redundant.我把它当作metronome的非限制性定语从句。E我能理解是松散型独立主格结构,A,E只是作用不同,不理解为什么A就是啰嗦了。 补充:是不是说A中redundant的是用了which又用that?假如直接是which produces...就不会有这个问题了? 求NN解答,谢谢
