Read the passage.That morning, our class had started the day with art. There was a knock at the door, and our teacher opened it to the concerned face of the school secretary. They bent their heads in hushed whispers. When our teacher returned to the front of the class, she announced that we were getting a "free” period to make art using any medium of our choosing. She directed us to pick out our materials and then retreated to her desk, a harrowed look on her face. She spent the rest of the period alternating between scrolling on her computer and staring out the window.
