Read the following summary of the Magic Music Downloads. The expressions in bold refer to time and amount. Underline the expression that you think is correct according to the graph.

The number of music downloads rose steadily from just under / well under 500,000 in 2000 to 1 million in 2004. By 2005 the number had doubled / trebled to exactly / approximately 2 million. 2006 showed a moderate fall in the number of downloads to nearly / over 1.5 million. Over the next year sales fluctuated before rocketing to 3 million this year. We still do not believe that the number of downloads has peaked and predict that the number will increase significantly / slightly over the next 3 to 4 years to well over 10 million.
