After several hours, we observed a significant improvement in their condition, indicating that the drug was effective in treating the disease. However, we also encountered some challenges during the experiment, such as unexpected results and difficulties in controlling variables. Despite these challenges, we learned a lot from the experiment and are confident that we can apply what we have learned to future research projects.
