5. some kind of bird, 它经常nest的地方被economic development破坏，所以一开始数量下降，但过了1~2年后又增了。Why?

A.      after the damage to local ecosystems, the ecosystem can soon restore significantly
C.      this bird can nest on road signs and xxx that have been built these years…
E  the development damages the living place of another animal, forcing them out in the open. And this animal is the food of the bird.  

Which is the correct answer? A or E? Both make some sense, but which is better?
