Galileo did not invent the telescope, but on hearing, in1609, that such an optical instrument had been made, he quicklybuilt his own device from an organ pipe and spectacle lenses.

A.   Galileo did not invent thetelescope, but on hearing, in 1609, that such an optical instrument had beenmade, he

B.    Galileo had not invented the telescope, but whenhe heard, in 1609, of such an optical instrument having been made,

C.   Galileo, even though he had not invented thetelescope, on hearing, in1609, that such an optical instrument had been made,he

D.   Even though Galileo did not invent thetelescope, on hearing, in 1609, that such an optical instrument had been made,

E.    Even though Galileo did not invent thetelescope, but when he heard, 1609, of such an optical instrument being made,he

我知道B中有其他错误，但是想知道为什么B中had not时态是错的，明明就又有一个过去式heard, A中 did not我觉得应had not.

A木有问题，had done一定要有明确过去时间比较的时候才能用，就好像had been made是在Galileo built his own device的对比下才出现的一样。表示在G做这个动作前已经完成。如果A的did not变成had not，没法解释啊，伽利略过去不能完成发明望远镜。。
