大家好，
文章背景(寫在其他段)是說聯準會蒐集資料來闡述利率和銀行準備金及銀行借貸多寡的
關係。
段落如下：
Banks in our sample held about 60 percent of total reserves as of
December 2018. On average, the ratio of bank reserves to total assets is
4 percent. Also, total loans make up near two-thirds of our sample banks'
total assets, and loans held by our sample banks constitute a material
fraction of total loans extended by commercial banks.

= significant

非常感謝，一開始我查cambridge dictionary沒有相關的意思，看了回覆後再去查merriam webster就有類似的了！
