birds overcome by pollution routinely fell
是 "birds that overcame by...."嗎?

vivid \$m[1]:D.birds overcome by pollutioin routinely fell from the sky above LA freeways,prompting officials in California to devise a plan to reduce

請問這裡的routinely fell from the sky 會不會錯誤修飾到pollution
In the mid-1970's, since birds were overcome by pollution, and routinely falling from the sky above Los Angeles freeways, this prompted officials in California to devise a plan that reduced automobile emissions.
C. birds had been overcome by pollution and routinely fell from the sky above Los Angeles freeways, prompting officials in California to devise a plan that reduced
個人覺得(C)可能的問題應該是在had been overcome 上面
過去完成是表一個在過去先發生的動作
但是在原文上看不出有什麼先後關係
但是不是錯在 had been overcome[過完].....and fell[過簡]
還是錯在had been overcome and (had) fell 後面缺少過去簡單式
我就不知道了![]()
還請NN指教
