Model Answer:

The graph shows the increase in the ageing population in Japan, Sweden and the USA. It indicates that the  percentage of elderly people in all three countries is expected to increase to almost 25% of the respective populations by the year 2040.       

In 1940 the proportion of people aged 65 or more stood at only 5% in Japan, approximately 7% in Sweden and 9% in the US. However, while the figures for the Western countries grew to about 15% in around 1990, the figure for Japan dipped to only 2.5% for much of this period, before rising to almost 5% again at the present time.       

In spite of some fluctuation in the expected percentages, the proportion of older people will probably continue to increase in the next two decades in the three countries. A more dramatic rise is predicted between 2030 and 2040 in Japan, by which time it is thought that the proportion of elderly people will be similar in the three countries.

The graph illustrates changes in the amounts of beef, lamb , chicken and fish consumed in a particular European country between 1979 and 2004.

In 1979 beef was by far the most popular of these foods , with about 225 grams consumed per person per week. Lamb and chicken were eaten in similar quantities (around 150 grams), while much less fish was consumed (just over 50 grams).

However, during this 25-year period the consumption of beef and lamb fell dramatically to approximately 100 grams and 55 grams respectively. The consumption of fish also declined , but much less significantly to just below 50 grams , so although it remained the least popular food, consumption levels were the most stable.

The consumption of chicken , on the other hand , showed an upward trend, overtaking that of lamb in 1980 and that of beef in 1989. By 2004 it had soared to almost 250 grams per person per wee.

Overall, the graph shows how the consumption of chicken increased dramatically while the popularity of these other foods decreased over the period.

TEST 4:

The graph below gives information from a 2008 report about consumption of energy in the USA since 1980 with projections until 2030.

Summaries the information by selecting and reporting the main features, and make comparisons where relevant.

The graph shows energy consumption in the US from 1980 to 2012, and projected consumption to 2030.

Petrol and oil are the dominant fuel sources throughout this period, with 35 quadrillion(35q) units used in 1980, rising to 42q in 2012. despite some initial fluctuation, from 1995 there was a steady increase. This is expected to continue, reaching 47q in 2030.  

Consumption of energy derived from natural gas and coal is similar over the period. From 20q and 15q respectively in 1980, gas showed an initial fall and coal a gradual increase, with the two fuels equal between 1985 and 1990. consumption has fluctuated since 1990 but both now provide 24q. coal is predicted to increase steadily to 31q in 2030, whereas after 2014, gas will remain stable at 25q.  

In 1980, energy from nuclear, hodro-and solar/wind power was equal at only 4 q. nuclear has risen by 3q, and solar/wind by 2. after slight increases, hydropower has fallen back to the 1980 figure. It is expected to maintain this level until 2030, while the others should rise slightly after 2025.  

Overall, the US will continue rely on fossil fuels, with sustainable and nuclear energy sources remaining relatively insignificant.
