Historical documents, statistical data, and art objects would be considered primary sources. Book reviews and magazines would be considered a primary source depending on how they are used.
Explanation:
A primary source are immediate first-hand accounts of something. Historical documents would be considered a primary source because they are first-hand accounts of the time period. Statistical data would also be considered a primary source because it is a first-hand account of a statistic (an example is on how many people die each year). Art objects would be considered a primary source because they usually are an account of something at the current time of the art's creation (see the Mona Lisa).
Book reviews and magazines could be considered primary sources, but they usually aren't as book reviews and usually not first hand accounts immediately, and magazines are often treated as non-first hand accounts, so magazines are not primary sources.
Helen is the wife of the Greek prince Menelaus. She was kidnapped by the Trojan prince, Paris, which then started the Trojan war because Paris refused to give her back.
