由录音的第一句话可知， 默克尔总理在欧洲的许多大事上都做出了贡献。 随后指出“The magazine said Merkel ‘stepped in’ every time Europe faced a serious crisis”， 也就是说， 每当欧洲面临危机， 她总是能帮助解决。 由此可知， 答案为D项。

【录音原文】
Time magazine has named German Chancellor Angela Merkel its 2015 “Person of the Year,” noting her leadership during the Syrian refugee crisis, the Greek economic bailout, currency turmoil in the European Union, and Russia's intervention in Ukraine. The magazine said Merkel “stepped in” every time Europe faced a serious crisis. It said while much of the world is debating the balance between safety and freedom, Merkel is asking Germany and the rest of the world to believe that great civilization build bridges, not walls. She says wars are won both on and off the battlefield.
