The diagram below shows how a home rainwater system works. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates how rainwater is collected, cleaned, stored and reused in a typical household system.

Overall, the process consists of four main stages, beginning with the collection of rain from the roof and ending with the water being pumped to the garden and toilets. There is also an overflow arrangement for when the storage tank is full.

In the first stage, rain falls onto the roof of the house and is collected, usually by gutters that channel it towards a downpipe. The water is then filtered to remove leaves and dirt, which prevents the system from becoming blocked and keeps the stored water relatively clean.

After filtering, the water is stored in a tank, where it remains until it is needed. In the final stage, a pump is used to send the water to the garden for watering and to the toilets for flushing. When the tank reaches its capacity, any additional rainwater is not wasted inside the system but flows out through an overflow pipe and returns to the stormwater drain.

In this way, the system allows households to reduce their use of mains water for purposes that do not require drinking-quality water.

Model answer: Academic Task 1 (20 minutes, at least 150 words)

The table below shows the average number of cups of coffee drunk and the average weekly spending on coffee by different age groups in Melbourne. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The table compares how many cups of coffee people in five age groups in Melbourne drink each week, and how much they spend on coffee.

Overall, coffee consumption and spending both peak among people aged 25 to 34 and then decline steadily with age. The two measures follow almost exactly the same pattern.

The 25–34 age group drinks the most coffee, at an average of 12 cups a week, and also spends the most, at $55. The 35–49 group is close behind, with 10 cups and $46 a week. The youngest adults, aged 18 to 24, drink slightly less, at 9 cups, and spend $41.

After the age of 50, consumption falls noticeably. People aged 50 to 64 drink 7 cups and spend $31 each week, while those aged 65 and over have the lowest figures, at just 5 cups and $20. In other words, the oldest group drinks less than half as much coffee as the 25–34 group and spends little more than a third as much.

The average cost per cup is fairly similar across all groups, at roughly $4 to $4.60.
