On 17 August 2018, there was a special event in my hometown. The mayor held a big competition of Pinang Climbing. This competition was held to celebrate the Independence Day. Early in the morning, many people had gathered in the town square. In the middle, there were exactly one hundred poles. Various prizes, such as t-shirts, radios, pans, and bicycles were hung on the top of each pole. At 10 o'clock, the competition started. Unlike the usual Pinang Climbing competition in which the competitors work individually, this time the competitors worked in teams. There were ten teams in this event. They would compete to get the prizes as many as they could. The crowd enjoyed watching the teams struggle to reach the top. They yelled and gave applauses every time a successful team grabbed the prizes and dropped them down. It was not an easy job to do because the pole was so slippery. Each pole had been covered with grease. However, all teams had good strategies. At about 12 a.m. nearly all the prizes had been taken away. It was an exciting experience. I myself cheered my favorite team so loudly that I nearly lost my voice. “It was not an easy job to do because the pole was so slippery.” What is the antonym of “slippery”?
