1981年至2000年某欧洲国家的燃料产量

The response covers all three fuels, gives a clear overview and makes relevant end-point comparisons. However, it misdates the start as 1980, shortens the petroleum plateau and places coal’s recovery too early. It also repeatedly uses tonnes, although the supplied chart does not identify a measurement unit.

Information is logically sequenced chronologically, with clear paragraphing that divides the period around 1990. Referencing and linking expressions such as “meanwhile”, “This figure” and “after which” generally make the progression easy to follow.

Vocabulary is flexible and precise for describing trends, with phrases like 'plummeted', 'soared', 'on a downward trajectory', and 'virtually unchanged', though occasional awkward phrasing such as 'the data of petroleum' appears.

A wide range of structures is used with generally good control, including subordinate and participial clauses. Errors are occasional and do not impede understanding, notably the article choice in “a first few years” and the extra space before the full stop after “trajectory”.
