Question

The fire spread through the hotel very quickly but everyone ____ get out .

A . had to      B . would       C . could       D . was able to

Answer 1

D

解析:

could 與 was able to 的區別，was able to 除了與 could 一樣表示“能……”外，還有如下意義：managed to do sth 或 succeeded in doing sth , 意即成功地做了某事、設法做成了某事。根據語境，顯然選D。
