to be responsible for something that happens

Soldiers who obey orders to commit atrocities should be answerable for their crimes. 士兵奉命犯下暴行，也必须为其行为承担罪责。

If you are answerable to someone, you have to explain your actions to them because they have the main control and responsibility.

Any European central bank should be directly answerable to the European Parliament. 任何欧洲中央银行都必须直接向欧洲议会负责。
