What is a limitation of a primary-source argument? 1. Irrelevant facts
2. Personal opinions
3. Verifiable information
4. Convincing conclusions

2. Personal opinions

Explanation:

Primary sources are documents written by people who have witnessed a historical event, for example, a soldier's diary in World War II is a primary source. Primary sources are essential for carrying out good research, as they are the first-hand account of a witness of the historic moment. However, these reports often lack a critical distance, that is, the authors of the sources are unable to separate personal thoughts and emotions from historical events, and can often present exaggerated and very emotional information.
