Reading Passage: “The Great Group Project Battle”
Group 4 was on the warpath the minute they heard their poster was missing. “This is a call to arms!” shouted Sam. Maya, trying to stay calm, said, “Let’s not go nuclear just yet.”
But then things heated up. Jay and Evan locked horns over who lost the poster, while Bella fired back with her side of the story. It was like a classroom war of nerves. “We need to close ranks,” Maya said, trying to calm them. “Fighting each other won’t help.”
Finally, the teacher stepped in and gave them new materials. “You’re not under attack,” she said. “No need to raise the white flag. Just rebuild.” Sam laughed. “Okay, no more heavy artillery let’s work.”
