風力発電の説明文です。1箇所発音が聞き取れません。

Wind power generation is becoming very popular, because it is one of the best ways to get energy. The first wind power generator was built in Denmark in 1891. Wind power generation has been popular there for many years. In japan there are now about 580 wind power generators. Many of them are in windy places near the sea,such as Hokkaido, Aomori , Akita and Okinawa . In Akita for example there are 67 wind power generators. These generators were made in Europe. We are getting more energy by wind power generatinon. Then (アバ) before we can say wind power generations is very useful wasy to get energy. Of course there are awesome problems we need a lot of money to make just one generator. And important parts only were for about 17 years. We have to think about the answers to these problems.
（　　）書のアバと聞こえる部分があります。前後の内容から想定して当てはまる単語を教えていただけませんか。

これ区切りと聞き取りの一部(then→than)が違うんじゃないでしょうか

は
And important parts only <wear> for about 17 years.
のような気がします

wear = 使用に耐える、使える、長持ちする = to stay in good condition after being used for a long time, もしくはto endure use : last under use or the passage of time

<intransitive verb>の1番

この回答へのお礼

回答ありがとうございます。thanがthenに聞こえていました。before
から推測することができますね。
それから、wear = 使用に耐える、使える、長持ちする も再度聞いてみるとwereと違ってますね。
丁寧なご指導ありがとうございました。
