Perspective is basically who wrote it and for what purpose? Like e.g. Source A might be a propaganda piece such as a poster designed to indoctrinate the German population whereas Source B could be a lecture delivered by a historian on Hitler's use of mass media or smth.
Since it's 10 marks, I would structure it by starting with a general statement on both the sources collectively.
Using the above example, maybe something along the lines of - Both sources provide valuable insight into the Nazi regime’s extensive use of propaganda as a tool for indoctrination. However, the perspectives offered are diverse due to a range of factors, including the origins of the source which in turn, determine the intent of it. ....
Then write about each source individually and account for the perspective.
E.g. Source A, a primary source, offers a first-hand perspective of the types of propaganda employed to .... Make sure to talk about author, what the poster entails, its purpose, all that analysis.
Then move on to Source B. - Conversely, Source A is an extract from a lecture delivered by a historian. As a secondary source, it provides a longitudinal analysis of the instrument of propaganda .... Talk about motive, audience, etc. and link to perspective.
There are other ways to go about a question like this, but that's how I think I would approach it!
