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 与 was able to 的区别，was able to 除了与 could 一样表示“能……”外，还有如下意义：managed to do sth 或 succeeded in doing sth , 意即成功地做了某事、设法做成了某事。根据语境，显然选D。
