The Task 1 paragraph that earns Band 7

The line graph illustrates changes in coffee and tea consumption across four regions between 2000 and 2020. Overall, coffee consumption rose substantially in every region while tea consumption declined or remained stable. The most striking change was in North America, where coffee consumption climbed from 4kg per person to over 7kg, an increase of roughly 75 percent. Tea consumption in the same region fluctuated marginally, finishing slightly below its 2000 figure.

Notice the structure — overview first (one sentence), then 2 grouped trends in detail. Five chart-description collocations stitched together. ~70 words; the full Task 1 needs roughly 170.
