The diagrams illustrate the changes that took place in a town between 1980 and 2000. Overall, the area underwent considerable transformation during this period, as the natural and agricultural landscape was largely replaced by a large lake, a hydroelectric dam, and tourist facilities, while the surrounding mountains remained mostly unchanged.
In 1980, the region was mainly rural and undeveloped. A river ran from north to south through the area. On the western side of the river, there was a forest, ancient structures, and a zone containing rare plants and animals. To the east, most of the land was used as irrigated farmland, and a small village was located in the south-eastern part. Mountains surrounded the area on several sides.
By 2000, the landscape had changed dramatically following the construction of a hydroelectric dam across the river in the south. This led to the formation of a large lake, which flooded most of the former farmland, forest, and wildlife areas. The lake was used for fishing, and a hotel was built on its eastern shore, indicating the development of tourism. In addition, electricity pylons were installed to supply power, and the village was relocated further south. However, the mountains around the region remained largely the same.

Lexical Resource - 9
- The vocabulary is sophisticated and highly appropriate for a geographic description (e.g., 'underwent considerable transformation', 'irrigated farmland', 'electricity pylons'). - Lexical items are used with full flexibility and precision, particularly regarding the impact of the dam (e.g., 'flooded', 'relocated'). - Spelling and word formation are flawless throughout.
