The question
The table gives information about the underground railway systems in six cities.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.
| City | Date opened | Length (km) | Passengers per year (millions) |
|---|---|---|---|
| City A | 1863 | 394 | 1180 |
| City B | 1900 | 214 | 1500 |
| City C | 1935 | 303 | 2500 |
| City D | 1969 | 199 | 1000 |
| City E | 1976 | 56 | 25 |
| City F | 1995 | 68 | 120 |
What to notice before you write
A table needs selection, not a list of every figure. Identify the extremes: City A is the oldest and longest, City C has the most passengers and City E the fewest. Notice that longer systems do not always carry more passengers: City B has fewer kilometres than City A but more passengers.
Band 7 sample report
The table provides data on the underground railway systems of six cities, including when they opened, how long they are and how many passengers they carry each year.
Overall, the oldest systems tend to be the longest, but the number of passengers does not depend only on length. City C carries by far the most passengers, while City E has the smallest system.
City A has the oldest network, which opened in 1863, and also the longest at 394 kilometres. However, it carries 1,180 million passengers a year, which is less than City B, whose 214-kilometre system carries 1,500 million, and much less than City C, with 2,500 million.
The newest systems are in City E and City F, which opened in 1976 and 1995 respectively. They are also the smallest, at 56 and 68 kilometres, and they handle only 25 million and 120 million passengers a year.
Finally, there is no simple link between age and passenger numbers, since City D, which opened in 1969, carries 1,000 million passengers a year, far more than the much newer systems in City E and City F.

What is an overview in Task 1?
The overview is a short paragraph, written without detailed numbers, that states the main trends or the most important features of the data. Reports without a clear overview are limited to a lower band.
Should I give my opinion in Task 1?
No. Describe and compare only what the data shows. Do not explain reasons or add information that is not in the chart.
