Three classmates must decide on a topic for their degree thesis. Alonso proposes blockchain, as he works in that field. Javier proposes artificial intelligence, as it is trendy. Dora proposes data science, as it relates to their business administration course. The author's intuition is that data science would be the best choice, as the students already have knowledge in that area and it is most likely to result in a good thesis. The conclusion is that the group should choose a topic that fits what they have studied, prioritizing data science, and work as a united, organized team to complete the project successfully.
