Multiple Choice

Consider the following equation: $$\mathrm { GHG } = \frac { \mathrm { GHG } } { \text { Energy } } \times \frac { \text { Energy } } { \mathrm { GDP } } \times \mathrm { GDP } ,$$
Where GHG = world annual emissions of greenhouse gases Energy = world annual amount of energy consumed GDP = world's annual gross domestic product
Suppose GHG emissions decreased by 6 percent between 2010 and 2012, a period when GDP increased by 4 percent and Energy/GDP decreased by 2 percent. We can conclude that

• A) decreased by 6 percent.
• B) remain unchanged.
• C) decreased by 4 percent.
• D) decreased by 8 percent.
• E) increased by 4 percent.
