Top 3 -Engineering projects

I made a test in my class to know the opinion of student about my list of engineering project. In my list I put Burj Khalifa, Golden Gate Bridge, Qingdao Haiwan Bridge, Hoover Dam and Brooklyn Bridge. The top 3 result is Golden Gate Bridge in first position, Burj Khalifa in second position and the Brooklyn Bridge in third positon. Personally, my top 3 is the Burj khalifa (1), the Golden Gate bridge (2) and the Hoover Dam (3). I have chosen these project because I want to take and speak about different project. Example I don’t want to speak about two bridge. So why I choose this top 3?…
