As the days went by, Steve and Alex made good progress on their project. They encountered some obstacles, but they worked together to overcome them. One day, while they were working on the final touches, Mrs. Johnson came over to check on their progress. 'How's it going, guys?' she asked. 'It's going great, Mrs. Johnson,' Steve replied. 'We've learned a lot about the Colosseum and we're happy with how our model turned out.' Mrs. Johnson smiled, looking impressed. 'I can see that you've put a lot of effort into this project. I'm proud of you both.' Steve and Alex beamed with pride, feeling happy and relieved that their hard work had paid off.
