문제 3Last Saturday, the temperature outside reached almost thirty-eight degrees, so my family decided to stay indoors for the entire day. At first, I worried that staying inside would be ①boring, but we found several fun activities to enjoy together. In the morning, we visited a nearby indoor climbing gym, where I learned some basic climbing techniques from an ②instructor. After lunch, we went to a small museum that had a special exhibition, and my younger brother was especially ③excited to see the huge whale model hanging from the ceiling. In the afternoon, we played board games at a cafe. By the time we got home, I realized that indoor activities could be just as ④boring as outdoor ones, especially during a ⑤heatwave.
