23 In a previous design, the weight of the discus used in track competition is concentrated in a metal center-but now it is lined with lead around the perimeter, thereby improving stability in flight and resulting in longer throws.
(A)   In a previous design, the weight of the discus used in track competition is concentrated in a metal center, but now it is
(B)   According to a previous design, the weight of the discus used in track competition was concentrated in a metal center, but now it is
(C)   Once designed with its weight concentrated in a metal center, the discus used in track competition is now
(D)   The discus used in track competition, once designed with its weight concentrated in a metal
center, but now
(E)   The discus used in track competition was once designed having its weight concentrated in a
metal center and now
关于B答案，OG官方解释是it在语法上指代weight.
it难道不是就近指代么？这样的话it在语法上也应该指代的是metal center。关于it指代这一块一直都很困惑，求大牛详细解释。

从句代词优先指代主句主语。
这里的主语是the weight所以it 优先指代the weight。

看看这个帖子，以前的NN们讨论的

同意楼上
it 优先指代前面的it(如果有的话) 然后就是指主语
which that 就近指代

谢谢楼上2位的指点哈，关于it指代明白了一些。

求此题正确句子的翻译啊~~！虽然可以根据时态和指代判断出正确答案，选完选项以后这个句子还是不很懂啊······ 主要是is concentrated in a metal center , 和 is lined with lead around the perimeter 是什么意思啊！！纠结

以前铁饼比赛里的铁饼是这么设计的：重量都集中在中心的金属部分上。而现在的铁饼把重量放在了铁饼周围的一圈包铅上

有主语的时候，首先指代主语

我也觉得应该是"重量"放在了铁饼周围, 而不是铁饼本身. 但是OG上的解释说it应该指代discus而非weight. 那就很奇怪了, 铁饼 is lead around the perimeter....??? 总觉得逻辑主语不对呀, 请NN解答!!
