    "corrected_essay": "The two maps compare changes in the layout of a specific university campus in 1975, 2002 and 2020.\n\nIn 1975, four main areas could be noticed in each corner of the university with several trees between them.\n\nIn the north-western corner, a sports center was situated, surrounded by a road which intersected another road leading to a lecture room in the south-eastern part. A library lay in the south-western end and on its opposite side, there was a drama room and a music room boarding a big car park.\n\nIn 2002, one striking change was that the sports center had been removed and an indoor one is planned for 2020. Also, the road running across the campus was demolished in order to make way for a science building in the center. But another new road will be built to connect the indoor sports center with the former library, which had been divided into two, so that half part served as an IT room. While the lecture room had become twice as large as it was in 1975, the original drama room was turned into a geology room, the place before which was built by the car park, so its capacity was enlarged.\n\nIn summary, great changes have occurred as this university had more constructions over these years."
