Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.

哪位NN可以告知，为什么不用having brought....呢？既然句中有since时间短语。

前面一个句子对后面造成的影响 现在分词或新名词出现是唯二可能的正选答案

strout

E) and brought

Subject is eagles. it doesn't make sense.

有同样的concern，这里有since时间短语，是否需要用完成时态呢？如何用？
