Hi, thanks for that Mr JDC,
Still not sure if it is Standard Grade cos the questions are almost always "How far do sources A/B agree / disagree about ..." but here goes the plan anyway:
"Sources A/B agree / disagree partially / to some extent / fully / not at all etc" (first make your judgement).
"They agree about ..... Source A says "..." and Source B says "..."" (say what they agree about (if anything), then quote from A then

"However, they disagree about .... Source A says "..." and Source B says ... (or even, but Source B doesn't mention anything about it)"
"In conclusion, Sources A/B agree / disagree fully / partially /not at all etc." If you want to make your conclusion really good you can then develop this overall judgement e.g. "Source A is mainly for the Nazis whereas Source B is mainly against them"
If you just quote without making the first comment on what they agree / disagree ABOUT you have to give more points of comparison.
