Based on the information provided in the above table, answer the following two questions.
(1) Develop one graph to display the historical annual world air freight traffic and world GDP from 2001 to 2010, using 2001 as the baseline year.
(2) Based on the historical world air freight traffic and world GDP data during 2001 and 2010, do you find the support for the argument that the world air freight grows about twice as fast as world GDP in the time period concerned? Explain how you prove whether this argument holds true.
