The two pie charts demonstrate changes in proportion of energy production from a country in 1985 and 2003.Both of charts contain six sources including oil,nuclear,natural gas and so on.
In the first pie chart, the proportion of oil was the most at 52%, which was 30% more than that from nuclear.The percentage of energy creation from coal accounted for 8%, two times of that from hydrogen.The ratios of natural gas and other renewable source were 13% and 1% respectively.
In 2003,the proportion of energy produced from oil decreased by 13%, meanwhile that from nuclear declined to 17%.However,the percentage of natural gas increased to about six times as much as that from hydrogen which was the same as that in 1985.The percentages of energy production from the coal and the other renewable sources increased slightly, occupying 13% and 4% of the total.
In conclusion, the percentage of energy production from oil and nuclear experienced a downtrend while those from coal and natural gas rose.

The twp pie charts demonstrate reasons for undergraduates and postgraduates to select Parker University respectively.Six reasons are depicted including reputation of university, location and so on.

In the second pie chart,the amount of postgraduates who choose the Parker University for reputation of university is the most,whose proportion is 42%, 10% more than that for cost.The percentages of postgraduates who choose for available of accommodation,location and personal recommendation are quite close at 8%, 6% and 6% separately.
In conclusion,the reputation of university is the most attractive reason for both undergraduates and postgraduates to choose Parker University to study.
