黃金29風力發電 - 英檢

請問黃金29"Electricity from Wind"

最後一題為什麼地3個答案對
(Responding to environmentalists concerned about birds killed by wind
turbines, analysts point to other human developments that are even more
dangerous to birds.)

而第四個錯呢?
(The wind energy produced by just a small number of states could supply all of
the power needs of the United States.)

我覺得第比較符合題目所給的->In the future, wind power is likely to become a major source of the world’s
energy supply.

請高手能指點~~
