The question

The two bar charts show approximate global food and oil prices at four selected milestones between 2000 and 2011. Food prices are measured in index points and oil prices in US dollars per barrel. The figures are rounded estimates from the original continuous line graph, not annual averages.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Adapted practice visual: BandLadder has redesigned the original continuous line graph as two bar charts showing four selected milestones. All plotted values are rounded visual estimates, not annual averages or a complete time series. Food index points and US dollars per barrel are shown separately; their numerical levels are not directly comparable.

Model answer

Band 8 sample answer

Band 8182 words. Every figure in the answer comes from the chart above.

The two bar charts compare the global food price index and the price of oil at four selected milestones from 2000 to 2011. Food is measured in index points, while oil is priced in US dollars per barrel. All figures are approximate rather than annual averages.

Overall, both measures increased considerably between the first and last observations, despite a sharp fall following their 2008 highs. Their subsequent recoveries differed: food exceeded its earlier high by early 2011, whereas oil did not.

At the start of 2000, the food price index stood at about 90 points. It reached approximately 220 at the selected high in 2008, before falling to around 140 in early 2009. By early 2011, it had recovered to roughly 240 points, the highest of the four food values shown.

Oil followed a similar sequence but recorded a larger proportional rise and fall. Its price increased from about $25 per barrel initially to approximately $135 in 2008. It then dropped to around $40 in early 2009 before recovering to about $100 by early 2011, still some $35 below its 2008 high.

Frequently asked questions

What should the overview say?+

Both measures rose substantially between the selected starting and ending points, with high values in 2008 followed by a steep fall by early 2009. By early 2011, food prices had exceeded their 2008 high, whereas oil remained below its earlier peak.

How many words and how long for IELTS Writing Task 1?+

At least 150 words; 170 to 200 is the safe range. Spend about 20 minutes on it and leave 40 for Task 2, which carries twice the marks.

How is IELTS Writing Task 1 scored?+

On four criteria: task achievement, coherence and cohesion, vocabulary, and grammatical range and accuracy. A clear overview of the main features is what most separates Band 6 from Band 7 and above.

How do I describe bar charts?+

Compare the biggest and smallest bars before anything else. If the bars show years, describe change; if they show places, describe rank. Round sensibly and say 'just over' or 'nearly' rather than guessing decimals.
