문제 4Dear residents, this notice explains how to use our apartment recycling area ①correctly. The recycling area, located behind the main entrance, is open every day from six to ten in the evening. First, sort your items into the ②labeled sections for paper, plastic, glass, and cans before dropping them off. Boxes should be flattened, and bottles should be emptied, because dirty items are ③hard to recycle. However, please do not leave ④small furniture or electronics in this area at any time. Instead, contact the management office to arrange a separate pickup for those bulky items. For example, broken chairs and old refrigerators require a special sticker before collection. In contrast to ordinary trash, recyclable materials must never be mixed together in one bag. Following these simple rules keeps our shared space ⑤tidy for every family.
