Now that you have some key facts about the London Millennium Footbridge, look at the graph on p. 77 in the coursebook. It shows the results of one of the tests carried out on the bridge. Study the graph carefully and try to answer these three questions:
1) What can you deduce about the test procedure?
2) What was the probable objective of the test?
3) What was the main result of the test?
After you do so, respond to the set of answers of at least one fellow student by evaluating his/her answer. If you disagree with any answer, you should explain why.
