Answer 1

C
句意：清洁的环境有助于该城市申办奥运会，而奥运会又转而促进该城市的经济发展。根据句意，可首先排除A项（本质上）、D项（事实上）。in turn--as a result of something in a series of events“相应地、转而”。如：I told Frank and he in turn told Helen.我告诉了弗兰克，而他又转而告诉了海伦。in return--in exchange or as payment作为……的交换、作为……的回报。如：Einstein did some homework for the little girl, and in return she gave him some cookies.综上所述，C项为正确答案。
