Apolitician running for office writes a book about her major accomplishments and charitable donations. what problem might a human have when trying to use the this book as a source for a historical argument ?

There's no actual history. The politician is only stating her side of things,which for most politicians is better than most. There is also the fact that she only talks about her good works and cheratable donations.There's no reliable historical facts or sources,about any given point in history.

Italy had political stability, wealth, and trade.
