Step 1: Europe revenue from the chart (million USD):
2004: about 190, 2005: about 280, 2006: about 390, 2007: about 500.
Step 2: Growth rates:
2005 over 2004: \(\dfrac{280-190}{190}=47.4\%\).
2007 over 2006: \(\dfrac{500-390}{390}=28.2\%\).
Step 3: Percent change in growth rate:
\[\frac{28.2-47.4}{47.4}\times100\approx -40.5\%\]The growth rate has fallen by about 40%; the option closest in size to 40 is 35 (60 and 20 are further away).
Final Answer:
The correct option is (3): 35.
