I want to know the answer to the following question:
Three protester climbed what to hang two banners on April 7, 2008?
All the background I'm provided with is that "On April 7, 2008, two days prior to the actual torch relay, three activists carrying Tibetan flags scaled the suspension cables of the Golden Gate Bridge to unfurl two banners, one saying "One World, One Dream.". Is that enough to answer the question?
Answer: yes
