Model answer (about 40 seconds)
"The bar chart shows the number of bike-share trips taken each month in Riverton from January to June, in thousands. Use was lowest in January, at 12,000 trips, and rose only slightly in February. From March the number climbed steeply, reaching 38,000 in April and peaking at 52,000 in May, more than four times the January figure. In June it fell slightly, to 49,000. Overall, the chart shows that bike-share use grew strongly through the spring and stayed high at the start of summer."
Why it works
- It names the image type, the topic, the unit and the period in the first sentence.
- It gives exact figures and compares them (lowest, peak, "more than four times"), which is what the higher Content levels describe.
- It varies the language for change: rose slightly, climbed steeply, peaking, fell slightly.
- It ends with a conclusion drawn from the data, not an opinion.
